Section 1
Overview
The Emerson PmPPC7448 module is a Processor PCI Mezzanine Card (PPMC). It is based on
the Freescale® Semiconductor PowerPC™ MPC7448 central processor unit and provides
additional processing power for the baseboard, which must be compatible with PPMC
architecture. The PmPPC7448 module supports various memory configurations, programmable user Flash memory, a PCI bridge/controller, three Ethernet interfaces, two serial
ports, as well as a real-time clock, and EEPROM.
COMPONENTS AND FEATURES
The following is a brief summary of the PmPPC7448 hardware components and features:
CPU: The Freescale MPC7448 RISC PowerPC microprocessor has an internal speed of up to 1.4
GHz and 166 MHz local bus speed. The MPC7448 includes 32 kilobytes separate level-one
(L1) data and instruction caches and 1 megabyte L2 cache. Standard power supply is 3.3
volts, with a configuration option for both 3.3 and 5 volts.
System Controller/PCI Bridge:
The Marvell® MV64460 (Discovery™III) is a single-chip solution that provides one PCI-X
bus, three integrated gigabit Ethernet Medium Access Control (MAC) controllers, twomegabit integrated Synchronous Random Access Memory (SRAM), four Independent
Direct Memory Access (IDMA) engines and two XOR Direct Memory Access (DMA) engines.
The 64-bit PCI interface can operate up to 66 MHz (60X) or 133 MHz (PCI-X).
SDRAM: The PmPPC7448 includes a 32M x 72-bit Double Data Rate (DDR) Synchronous Dynamic
Random Access Memory (SDRAM) Small-Outline Dual In-line Memory Module (SO-DIMM).
Options include 256 megabytes, 512 megabytes, 1 gigabyte, and 2 gigabytes. The interface implements eight additional bits to permit the use of error-correcting code (ECC). The
MV64460 bridge acts as the memory controller.
Flash: The PmPPC7448 includes Flash configuration options of 32 or 64 megabytes. The
PmPPC7448 is capable of booting from either an 8-bit, 32-pin PLCC ROM socket on the
Development Mezzanine Card (DMC) or from 32-bit soldered Flash (default).
Serial I/O: The PmPPC7448 includes up to two EIA-232 ports operating between 9600 and 115,200
baud. Serial port one is always routed to the Development Mezzanine Card (DMC) serial
connector; build options include connections to the front panel serial connector, or the P14
connector. When routed to P14, the port has the option of either EIA-232 or TTL signaling
levels. Serial port two is routed to P14 with the same signaling options.
Ethernet: The PmPPC7448 includes three Ethernet ports. Two Broadcom BCM5461S gigabit PHY
devices route Ethernet (ports 0 and 1) through connector P14. The Micrel KSZ8721CL
10/100 PHY device routes Ethernet (port 2) through a mini-USB connector on the front
panel. The Broadcom and Micrel devices are IEEE 802.3-compliant.

1-1
Overview:
Components and Features
Note: GbE ports (0 and 1) are routed through the PHYs directly to connector P14. Therefore, magnetics are
required on the Rear Transition Module (RTM) or baseboard.
CPLD: The PmPPC7448 uses a Complex Programmable Logic Device (CPLD) to implement various
memory-mapped registers and to control access to the Flash, ROM socket, and enumeration of Monarch/non-Monarch systems.
RTC: The real-time clock is an ST®Microelectronics M41T00 Serial Access Timekeeper®.
Development Mezzanine Card (DMC):
The DMC is a custom, optional plug-on card mounted on the back of the PmPPC7448. This
card facilitates hardware and software development. See Chapter 10.

Section 2
Setup
This chapter describes the physical layout of the boards, the setup process, and how to
check for proper operation once the boards have been installed. This chapter also includes
troubleshooting, service, and warranty information.
ELECTROSTATIC DISCHARGE
Before you begin the setup process, please remember that electrostatic discharge (ESD)
can easily damage the components on the PmPPC7448 hardware. Electronic devices, especially those with programmable parts, are susceptible to ESD, which can result in operational failure. Unless you ground yourself properly, static charges can accumulate in your
body and cause ESD damage when you touch the board.
Caution: Use proper static protection and handle PmPPC7448 boards only when absolutely
necessary. Always wear a wriststrap to ground your body before touching a board. Keep
!
your body grounded while handling the board. Hold the board by its edges–do not touch
any components or circuits. When the board is not in an enclosure, store it in a staticshielding bag.
To ground yourself, wear a grounding wriststrap. Simply placing the board on top of a
static-shielding bag does not provide any protection–place it on a grounded dissipative
mat. Do not place the board on metal or other conductive surfaces.
PMPPC7448 CIRCUIT BOARD
The PmPPC7448 is a fourteen-layer circuit board that conforms to the IEEE 1386 Common
Mezzanine Card (CMC) standard. It has the following physical dimensions:

Reset
The reset signals are routed to the CPLD, unless stated otherwise. See Chapter 7 for the
reset registers. The following sources can reset the PmPPC7448:
Power-on: This causes a hard reset to the entire board, including the PCI interfaces.
Front panel: This reset switch is accessible through a small hole in the front panel and causes a hard reset
to the entire board, including the PCI interfaces.
Caution: Use minimal force when pressing the front panel reset switch. Excessive force may damage
the switch.
!
PCI RESET: This causes a hard reset to the entire board, including the PCI interfaces.
COP HRESET: This reset is activated by the common on-chip processor (COP) debugger interface via a
header located on the Development Mezzanine Card (DMC). It causes a hard reset to the
entire board, including the PCI interfaces.
COP SRESET: This reset is activated by the COP debugger interface and causes a soft reset to the Freescale MPC7448 and a reset to Flash.
COP TRST: This is routed directly to the MPC7448 TRST.
PMC TRST: This is routed directly to the MV64460 TRST.
Software controlled: The software controlled resets are described in the Reset Command register, Register
Map 7-2.

Power Requirements
Be sure your power supply is sufficient for the PmPPC7448 circuit board. Standard power is
3.3 volts, however a dual power supply option is available. Table 2-2 lists the board’s specific
power requirements.
Table 2-2: Power Requirements
Voltage:
Range:
Current
(typical):
+3.3 V
+/- 5%
5.1 amps
Watt Requirements/Configuration:
1 GHz MPC7448 and 1 GB DDR SDRAM
configuration typically requires 17 watts
Specific PmPPC7448 configurations may draw over 20 watts of power. The configurations
with a faster core CPU frequency and increased DDR memory draw more power and generate more heat. When monitoring the ambient air temperature increase across the module
(from the inlet side of the PmPPC7448 to the outlet), the temperature can rise approximately 4-7° C at high airflow (300 lfm) to 5-12° C at low airflow (100 lfm). The system
designer should consider the cumulative effects of installing multiple PMC modules on a
single carrier and ensure adequate airflow.
Environmental Considerations
As with any printed circuit board, be sure that air flow to the board is adequate. Chassis
constraints and other factors greatly affect the air flow rate. The environmental requirements are as follows:
Table 2-3: Environmental Requirements
Environment:
Range:
Relative Humidity:

PROCESSOR RESET
Circuitry on the PmPPC7448 module resets the processor and the board. It activates the
RESET_OUT* signal on pin 60 of the P12 connector if the module voltages fall out of tolerance or if the optional on-board reset switch is activated. A COP SRESET causes a soft reset
to the processor, see the Reset Command register in Register Map 7-2.
PROCESSOR INITIALIZATION
Initially, the PmPPC7448 powers up with specific values stored in the CPU registers. The initial power-up state of the Hardware Implementation Dependent register (HID0) and the

EXCEPTION HANDLING
Each CPU exception type transfers control to a different address in the vector table. The
vector table normally occupies the first 0x2000 bytes of RAM (with a base address of
0000,000016) or ROM (with a base address of F800,000016). An unassigned vector position
may be used to point to an error routine or for code or data storage. Table 3-3 lists the processor exceptions starting with the highest priority per the following four exception classes.
Asynchronous: Nonmaskable exceptions have priority over all other exceptions. These exceptions cannot
be delayed and do not wait for completion of any precise exception handling.

EXCEPTION PROCESSING
When an exception occurs, the address saved in Machine Status Save/Restore register 0
(SRR0) helps determine where instruction processing should resume when the exception
handler returns control to the interrupted process. Machine Status Save/Restore register 1
(SRR1) is used to save machine status on exceptions and to restore those values when an rfi
instruction is executed.
When an exception is taken, the MPC7448 controller uses SRR0 and SRR1 to save the contents of the Machine State register (MSR) for the current context and to identify where

CACHE MEMORY
L1 Cache
The MPC7448 processor implements two separate 32-kilobyte, level-one (L1) instruction
and data caches that are eight-way, set-associative. The L1 supports a four-state modified/exclusive/shared/invalid (MESI) cache coherency protocol. The caches also employ
pseudo least-recently-used (PLRU) replacement algorithms within each way.

On-Card Memory Configuration
The PmPPC7448 includes the following memory devices:
• Up to 64 megabytes of Flash memory
• Synchronous DRAM (SDRAM) configurations up to 2 gigabytes
• Eight kilobytes of non-volatile memory
BOOT MEMORY CONFIGURATION
The PmPPC7448 boot default is the on-board Flash which occupies the physical address
space beginning at E800,000016. Selecting jumper JP2 on the optional Development Mezzanine Card (DMC) allows the 8-bit ROM socket as the boot device (see “DMC Jumpers
(JP1)” on page 10-9). Read bit 3 of Board Configuration register 1 at F820,A00016 (see Register Map 7-11) for the boot device selection.

The MV64460 controls the access time for ROM. The default power-up timing allows
boards of any speed to work with ROMs that have access times faster than 150 nanoseconds. We strongly suggest that you use the default timing because of the inherent risks of
optimizing timing for a specific configuration.
USER FLASH
This configuration supports one bank of Flash memory. The PmPPC7448 circuit board
accommodates two Intel StrataFlash™ devices (each 16 bits wide), allowing for as much as
64 megabytes of 32-bit wide user Flash at location E800,000016. One megabyte at the base
of Flash is reserved for the monitor. The following table shows the configuration options.

The Flash devices interface to the most significant data bits of the PowerPC data bus. For
example, if the data path is 64 bits wide, the PowerPC data bus is declared as D[0:63],
where D0 is the most significant bit and D63 is the least significant bit. For a 32-bit data
path, the Flash devices interface to D[0:31]. For a 16-bit path, the data bus is D[0:15].

On-Card Memory Configuration:
On-Card SDRAM
If booting from user Flash, the MV64460 controller initially maps one megabyte addressing
of Flash memory (beginning at FF80,000016) at the top of the address space. When an 8-bit
Flash device is installed in the PLCC socket, it always appears at F800,000016 (and is mirrored at FF80,000016 when the socket is the boot device).
Caution: When removing socketed PLCC devices, always use an extraction tool designed specifically
for that task. Otherwise, you risk damaging the PLCC device.
!
Since the 16-bit Flash device is soldered, an 8-bit ROM could be used to bootstrap the processor and execute a routine that programs the soldered Flash from a serial port, Ethernet,
or through the PCI interface.
ON-CARD SDRAM
The PmPPC7448 supports 256 megabyte, 512 megabyte, 1 gigabyte, and 2 gigabyte configurations of 72-bit wide SDRAM. This interface implements eight additional bits to permit
the use of error-correcting code (ECC).
A low profile, small-outline, dual inline memory module (SO-DIMM) is installed to reduce
board density and routing constraints. A serial EEPROM on the module provides the serial
presence detects (SPD). On-card SDRAM occupies physical addresses from 0000,000016 to
7FFF,FFFF16. The SDRAM is controlled by the MV64460 DRAM controller, which may be programmed for most memory sizes and speeds, various block sizes, and write protection.
In addition to the basic SDRAM control functions, the MV64460 chip provides several additional DRAM-related functions and contains the following performance enhancing features:
• Supports page mode—minimizing SDRAM cycles on multiple transactions to the same
SDRAM page and can be configured to support up to 16 simultaneously opened pages.
• Supports error-correcting code (ECC) and read-modify-write (RMW) in the case of
partial writes (smaller than 64-bit) to DRAM.
• ECC provides single bit correction and two bits detection.
NVRAM ALLOCATION
The PmPPC7448 uses an eight kilobyte SROM attached to the MV64460 bridge for storing
non-volatile information such as board, monitor, and operating system configurations, as
well as information specific to user application. All Emerson-specific data is stored in the
upper two kilobytes of the device. The remainder of the device is available for user application. Table 4-3 defines the organization of data within the SROM.

System Controller
The Marvell MV64460 is an integrated system controller with a PCI interface and communication ports for high performance embedded control applications. The MV64460 has a five
bus architecture:
• A 64-bit interface to the CPU bus
• A 64-bit interface to DDR SDRAM
• A 32-bit interface to devices
• Two 64-bit PCI/PCI-X interfaces, only PCI0 is used on the PmPPC7448
These interfaces are connected through a crossbar fabric, or central routing unit, which
enables simultaneous operation of the CPU bus, PCI device, and access to memory. The
crossbar fabric contains programmable arbitration mechanisms to optimize device performance.
The MV64460 communications unit includes the following:
• Three Ethernet ports
• Two multi-protocol serial controllers (MPSC)
• Ten serial DMAs (SDMA)
• Two baud rate generators (BRG)
• I2C interface
Note: Proprietary information on the Marvell MV64460 device is not available in this user’s manual. Please refer to

CPU INTERFACE
CPU interface features include:
• 32-bit address and 64-bit data buses
• Support for Symmetrical Multi-Processing (SMP) in both 60x and MPX bus modes
• Support for up to four slave devices on the same 60x bus
• 166 MHz CPU bus frequency
• CPU address remapping to the PCI
• Support for access, write, and caching protection to a configurable address range
• Support for up to 16 pipelined address transactions
CPU Interface Registers
The PmPPC7448 monitor configures the MV64460 controller so that it provides these 32bit registers to the PowerPC processor in the correct byte order (assuming the access width
is 32 bits). The CPU setting of the CPU Configuration register affects the MV64460 behavior
on subsequent CPU accesses. This register activates with transactions pipeline disabled. In
order to gain the maximum CPU interface performance, change this default by following
these steps:
1 Read the CPU Configuration register. This guarantees that all previous transactions in the
CPU interface pipe are flushed.
2 Program the register to its new value.
3 Read polling of the register until the new data is being read.
Caution: Setting the CPU Configuration register must be done only once. For example, if the CPU
interface is configured to support Out of Order (OOO) read completion, changing the
!
register to not support OOO read completion is fatal.
MEMORY INTERFACE
DDR SDRAM Controller
The DDR SDRAM controller supports up to four DRAM banks. It has a 16-bit address bus
(M_DA[13:0] and M_BA[1:0]) and a 72-bit data bus (M_DQ[63:0] and M_CB7[7:0]). The
DRAM controller supports two DDR DRAM DIMMs—registered and unbuffered. Other features include:
• 64-bit wide (+ 8-bit ECC) SDRAM interface

• Up to 166 MHz clock frequency
• Support for 256 megabytes to 2 gigabytes
• Up to two gigabytes address space per DRAM bank
• Supports both physical bank (M_CS[3:0]) and virtual bank (M_BA[1:0]) interleaving
The MV64460 has a number of SDRAM registers. Refer to the Marvell web site for available
documentation.
Internal SRAM
The MV64460 integrated SRAM occupies two megabits of space for general purpose memory. The SRAM is cleared on reset by the monitor to initialize ECC. ECC implementation is
based on 8-bit ECC code per 64-bit of data. ECC support includes:
• Single bit error correction, two bits error detection
• Read-modify-write in case of partial write
• Single bit errors cleanup
• Single and double bit error counters
• Force bad ECC
DEVICE CONTROLLER INTERFACE
The device controller supports up to five banks of devices. Each bank’s supported memory
space can be programmed separately in one megabyte quantities, up to 512 megabytes of
address space, with a total device space of 2.5 gigabytes. Other features include:
• Dedicated 32-bit multiplexed address/data bus (separate from the SDRAM bus)
• Up to 133 MHz bus frequency
• Five chip selects, each with programmable timing
• Use as a high bandwidth interface to user specific logic
• Supports many types of standard memory devices

System Controller:
Internal (IDMA) Controller
Device Control Registers
Each bank has its own parameters register and can be programmed to 8, 16, or 32-bits
wide. The device interface consists of 128 bytes of write buffer and 128 bytes of read
buffer.
INTERNAL (IDMA) CONTROLLER
Each of the four DMA engines can move data between any source and any destination, such
as the SDRAM, device, PCI_0, or CPU bus. These engines optimize system performance by
moving large amounts of data without significant CPU intervention. Read and write are
handled independently and concurrently.
Timer/Counter
Each of the four 32-bit wide timer/counters can be selected to operate as a timer or a
counter. Each timer/counter increments with every TCLK rising edge. In counter mode, the
counter counts down to terminal count, stops, and issues an interrupt. In timer mode, the
timer counts down, issues an interrupt on terminal count, reloads itself to the programmed
value, and continues to count. Reads from the counter or timer are completed directly from
the counter, and writes are to the timer/counter register.
PCI INTERFACE
The Emerson PmPPC7448 module complies with the PCI mezzanine card (PMC) form factor
for peripheral component interconnect (PCI) modules and the specification for Processor
PCI Mezzanine Cards (PPMC). The MV64460 supports two 64-bit PCI interfaces, compliant
to the PCI Local Bus Specification revision 2.3. Only PCI0 is functional on the PmPPC7448.
Other features include:
• Support for PCI-to-PCI memory, I/O, and configuration transactions between the two
PCI interfaces
• Support for PCI-to-PCI-X bridging between the two PCI interfaces
• PCI bus speed up to 66 MHz in conventional PCI mode or up to 133 MHz in PCI-X mode
• When both PCI interfaces are functional, they operate in asynchronous clocks to each
other and to the MV64460 core clock
• 32/64-bit PCI master and target operations

PCI Configuration Space
The PCI slave supports Type 00 configuration space header as defined in the PCI specification. The MV64460 is a multi-function device and the header is implemented in all five
functions. The PCI interface implements the configuration header and this space is accessible from the CPU or PCI bus.
PCI Subsystem Device and Vendor ID Assignment
The PmPPC7448 has been assigned the following PCI identification number.
Figure 5-2: PCI Device and Vendor ID
Vendor ID:
Device ID:
Description:
0x1223
0x003F
Reported by the PCI bridge
The PmPPC7448 sets the PCI revision ID to the hardware version number located in the
CPLD’s Hardware Version register (Register Map 7-8).
PCI Read/Write
The MV64460 becomes a PCI bus master when the CPU, IDMA, gigabit Ethernet controller,
or MPSC SDMAs initiate a bus cycle to a PCI device. Conventional PCI mode allows unlimited
DMA bursts between PCI and memory. PCI-X mode supports up to four split transactions
and write combining. It supports all PCI commands including 64-bit addressing using dual
access cycles (DAC).
The MV64460 acts as a target when a PCI device initiates a memory access (or an I/O access
in the case of internal registers, or a P2P transaction). It responds to all memory read and
write accesses, including DAC, and to all configuration and I/O cycles in the case of internal
registers. Its internal buffers allow unlimited burst reads and writes, and can support up to
four pending delayed reads in conventional PCI mode and up to four split read transactions
in PCI-X mode.
The PCI0 address map is illustrated in Monarch mode in Fig. 5-3, and in non-Monarch mode
in Fig. 5-4.
Note: Fig. 5-3 is a typical example depending on the PCI system and only if another PmPPC7448 in the system rack
is the Monarch. Depending on the host, the PCI memory space may shift.

PCI Interface Registers
PCI0 and PCI1 contain the same set of internal registers, but are located at different offsets.
A CPU access to the MV64460 PCIx Configuration register is performed via the PCIx Configuration Address and Data registers. Only PCI0 is functional on the PmPPC7448.
All PCI configuration registers are located at their standard offset in the configuration
header, as defined in the PCI specification, when accessed from their corresponding PCI
bus. For example, if a master on PCI0 performs a PCI configuration cycle on PCI’s Status and
Command register, the register is located at 0x004.
The PmPPC7448 module may generate interrupts to other PCI devices by accessing doorbell-type interrupt-generating registers or address ranges within their PCI bridges. The
module will respond to interrupts caused by another PCI device when it accesses a programmable range of local memory, as provided by the MV64460 memory controller. In
addition, it may monitor the state of the PCI bus INTA*—INTD* signals routed directly to the
memory controller’s multipurpose pins (MPP). The MV64460 contains registers that control the masking, unmasking, and priority of the PMC interrupts as inputs to the processor.
PCI BUS CONTROL SIGNALS
The following signals for the PCI interface are available on connectors P11, P12, and P13.
Refer to the PCI specification for details on using these signals. All signals are bi-directional
unless stated otherwise. A sustained tri-state line is driven high for one clock cycle before
float.
Note: The PmPPC7448 host board must adhere to the PCI Local Bus Specification (Revision 2.3) for terminating
JTAG signals.
ACK64*: ACKNOWLEDGE 64-bit TRANSFER This sustained three-state signal indicates the target is
willing to transfer data using 64 bits.
AD[31:00]: ADDRESS and DATA bus (bits 0-31) These three-state signals are used for both address
and data handling. A bus transaction consists of an address phase followed by one or more
data phases.
AD[63:32]: ADDRESS and DATA bus (bits 32-63) These provide 32 additional bits. During an address
phase the upper 32-bits of a 64-bit address are transferred; otherwise these bits are
reserved. During a data phase, an additional 32-bits of data are transferred when a 64-bit
transaction has been negotiated by the assertion of REQ64* and ACK64*.
C/BE[3:0]*: BUS COMMAND and BYTE ENABLES These three-state signals have different functions
depending on the phase of a transaction. During the address phase of a transaction these
lines define the bus command. During a data phase the lines are used as byte enables.

PCI Bus Control Signals
C/BE[7:4]*: BUS COMMAND and BYTE ENABLES During the address phase, the actual bus command is
transferred, otherwise these bits are reserved. During a data phase the lines are used as
byte enables.
CLK: CLOCK This input signal to PPMC modules provides timing for PCI transactions.
DEVSEL*: DEVICE SELECT This sustained three-state signal indicates when a device on the bus has
been selected as the target of the current access.
EREADY: READY This signal is an input for Monarch modules and an output for non-Monarch modules. It indicates that all modules are initialized and the PCI bus is ready to be enumerated.
FRAME*: CYCLE FRAME This sustained three-state signal is driven by the current master to indicate
the beginning of an access, and continues to be asserted until the transaction reaches its
final data phase.
GNT*: GRANT This three-state signal indicates that access to the bus has been granted to a particular master. Each master has its own GNT*.
IDSEL: INITIALIZATION DEVICE SELECT This input signal acts as a chip select during configuration
read and write transactions.
INTA*, INTB*, INTC*, INTD*:
PMC INTERRUPTS A, B, C, D These open drain lines are used by the PPMC module to interrupt the baseboard, or vice versa.
IRDY*: INITIATOR READY This sustained three-state signal indicates that the bus master is ready
to complete the data phase of the transaction.
M66EN: ENABLE 66 MHZ This signal indicates to a device whether the bus segment is operating at
66 or 33 MHz in conventional PCI.
MONARCH*: MONARCH When this signal is grounded, it indicates that the PPMC module is a Monarch
and must provide PCI bus enumeration and interrupt handling.
PAR: PARITY This is even parity across AD[31:00] and C/BE[3:0]*. Parity generation is required
by all PCI agents. This three-state signal is stable and valid one clock after the address
phase, and one clock after the bus master indicates that it is ready to complete the data
phase (either IRDY* or TRDY* is asserted). Once PAR is asserted, it remains valid until one
clock after the completion of the current data phase.
PAR64: PARITY UPPER DWORD This three-state signal is the even parity bit that protects
AD[63:32] and C/BE[7:4]*.
PERR*: PARITY ERROR This sustained three-state line is used to report data parity errors during all
PCI transactions except a Special Cycle.

PRESENT*: PRESENT When grounded, this input signal indicates to a carrier that a PPMC module is
installed.
RESET_OUT*: RESET OUTPUT This output signal may be used to support a reset button or other reset
source on the PPMC module. It is an open drain output from the PPMC module that
becomes an input to the reset logic on the carrier card. To avoid reset loops, do not use
RST* to generate RESET_OUT*.
REQ64*: REQUEST 64-bit TRANSFER When asserted by the current bus master, this sustained
three-state line indicates the ability to transfer data using 64 bits.
REQ*: REQUEST This three-state signal indicates to the arbiter that a particular master wants to
use the bus.
RST*: RESET The assertion of this input signal brings PCI registers, sequencers, and signals to a
consistent state. The carrier card generates this system reset signal (pull-up resistor
required) as an input to all PPMC modules.
SERR*: SYSTEMS ERROR This open-drain output signal is used to report any system error with
catastrophic results.
STOP*: STOP A sustained three-state signal used by the current target to request that the bus
master stop the current transaction.

System Controller:
Doorbell Registers
DOORBELL REGISTERS
The MV64460 uses the doorbell registers in the messaging unit (MU) to request interrupts
on both the PCI and CPU buses. There are two types of doorbell registers:
Outbound: These are set by the MV64460’s local CPU to request an interrupt service on the PCI bus.
Inbound: These are set by an external PCI agent to request interrupt service from the local CPU.
Outbound Doorbells
The local CPU generates an interrupt request to the PCI bus by setting bits in the Outbound
Doorbell register (ODR). The interrupt may be masked in the Outbound Interrupt Mask register (OIMR), but that does not prevent the bit from being set in the ODR. The ODR is
located at PCI_0 offset 0x1C2C.
Note: The CPU or the PCI interface can set the ODR bits. This allows for passing interrupt requests between CPU and
PCI interfaces.
Inbound Doorbells
The PCI bus generates an interrupt request to the local CPU by setting bits in the Inbound
Doorbell register (IDR). The interrupt may be masked in the Inbound Interrupt Mask register (IIMR), but masking the interrupt does not prevent the bit from being set in the IDR. The
IDR is located at PCI_0 offset 0x1C20.
Note: The interrupt request triggered from the PCI bus can be targeted to the CPU or to the PCI interface, depending
on the software setting of the interrupt mask registers.
MONARCH FUNCTIONALITY
The PmPPC7448 can be configured to function as either a Monarch or non-Monarch module, as described in the VITA 32 PPMC specification. A Monarch is the main PPMC device on
the local PCI bus. It performs enumeration on that bus after power-up and is often the interrupt handler. A non-Monarch module does not perform enumeration on the local bus after
power-up. Bit 2 of Board Configuration Register 3 (see Register Map 7-10) at location
F820,C00016 indicates how the module is configured (0=non-Monarch, 1=Monarch), as
determined by the signal on pin 64 of connector P12. The software can read the Monarch
line status to configure the board, and the hardware is unaffected.
The EReady register (see Register Map 7-7) at location F820,500016 has an additional bit to
support Monarch functionality. EREADY bit 0 monitors the EREADY line. For a non-Monarch, it is presumed that this signal is initially asserted, then removed when the bus is ready
for enumeration. When all the other PCI devices have stopped driving this signal low, the
Monarch will enumerate the bus. Please see the PPMC standard (reference in Table 1-3) for
carrier board pull-up requirements.

PmPPC7448 User’s Manual

System Controller:
66 MHz Bus Operation
66 MHZ BUS OPERATION
Conventional PCI: In order for the PCI bus to operate at 66 MHz, all devices on the bus must be capable of that
speed. When the M66EN signal (connector P12 pin 47) is high for a particular PCI device, it
indicates that the device can operate at 66 MHz. For 33 MHz modules, M66EN is grounded,
so the signal will be high only when all devices on the PCI bus are capable of operating at 66
MHz. Software can read bit 21 of the PCI Status and Command register to determine the
bus speed. If bit 21 is high, the bus speed is 66 MHz; if it is low, the bus speed is 33 MHz. If
any PCI device pulls the wire or M66EN signal low, then the bus speed will be 33 MHz for all
of the devices. Please see the PPMC standard (reference in Table 1-3) for carrier board pullup requirements.
WATCHDOG TIMER
The 32-bit count down watchdog timer generates a nonmaskable interrupt or resets the
system in the event of unpredictable software behavior. After the watchdog is enabled, it is
a free-running counter that requires periodic servicing to prevent its expiration. After reset,
the watchdog is disabled.
RESET
Circuitry on the PmPPC7448 resets the entire module if the voltages fall out of tolerance
(due to power-on reset) or if the optional on-board reset switch is activated. The Marvell
MV64460 control register settings are initialized immediately following this reset to configure the module properly before allowing any external PCI accesses to occur. The MV64460
supports three reset pins:
SYSRST*: SYSRST* is the main reset pin. When asserted, all MV64460 logics are in a reset state and all
outputs are floated, except for DRAM address and control outputs. SYSRST* is separated
from the PCI reset pins so the CPU can boot and start to initialize the board before the PCI
slot reset signal is deasserted.
PCI0_RST* and PCI1_RST*:These pins are the independent PCI interface reset pins. The PCI is kept in a reset state as
long as its corresponding reset pin is asserted. On reset deassertion, all PCI configuration
registers are set to their initial values as specified in the PCI specification. The two methods
of PCI reset configuration include: pins sampled on SYSRST* deassertion and serial ROM initialization. Only PCI0 is functional on the PmPPC7448.
Caution: When the MV64460 is in reset, any other attempts for PCI device access is ignored.
Therefore, use RESET_OUT and drive RST as long as it is asserted or wait for EReady
!
assertion before attempting an access.

Section 6
Ethernet Interface
The PmPPC7448 provides three independent full duplex Ethernet ports. Using the Marvell
MV64460, these ports are configured to one 10/100 Mbps Media Independent Interface
(MII) and two 10/100/1000 Mbps Gigabit MII (GMII). The two gigabit Ethernet ports (ports
0 and 1) are routed through PMC connector P14. The 10/100 Mbps Ethernet port (port 2) is
routed to the front panel mini-USB connector.
Note: Since GbE ports 0 and 1 are routed through the PHYs directly to connector P14, magnetics are required on
the Rear Transition Module (RTM) or baseboard.
Some additional Ethernet features on the MV64460 include:
• IEEE 802.3 compliant MAC layer function
• 10/100/1000 megabit operation — half and full duplex are automatically mapped out
through the PHY
• IEEE 802.3x flow-control for full duplex operation mode and back pressure for half
duplex mode
• Internal and external loop back modes
• Short frame transmission (less than 64 bytes) zero padding and long frame transmission
(limited only by external memory size)
The Micrel KSZ8721CL 10/100BASE-TX/FX and two Broadcom BCM5461S 1000BASET/100BASE-TX/FX/10BASE-T transceivers provide:
• Compliance with IEEE 802.3 standards
• Compliance with PICMG 2.15 standards
• Low power consumption; less than 340 mW
• IEEE 1149.1 (JTAG) boundary scan chain support
Note: Proprietary information on the Micrel and Broadcom Ethernet transceiver devices is not available in this
user’s manual. Please refer to the Micrel web site at http://www.micrel.com or the Broadcom web site at
http://www.broadcom.com for available documentation.
MV64460 ETHERNET REGISTERS
The MV64460 is capable of implementing three 10/100/1000 Ethernet controllers. These
controllers interface with the PHY via MII or GMII interface.
The Serial Management Interface (SMI) unit continuously queries the PHY devices for their
link status. The PHY addresses for the link query operation are programmable per port in
the PHY_Address register.

Ethernet Address
ETHERNET ADDRESS
The Ethernet address for your board is a unique identifier on a network and must not be
altered. The address consists of 48 (MAC[47:0]) bits divided into two equal parts. The upper
24 bits define a unique identifier that has been assigned to Emerson Network Power by
IEEE. The lower 24 bits are defined by Emerson for identification of each of our products.
The Ethernet address for the PmPPC7448 is a binary number referenced as 12 hexadecimal
digits separated into pairs, with each pair representing eight bits. The address assigned to
the PmPPC7448 has the following form:
00 80 F9 xx yy zz
00 80 F9 is Emerson’s identifier. The last three bytes of the Ethernet address comprise the
data for the Ethernet addresses in non-volatile memory (NVRAM). The PmPPC7448 has
been assigned the Ethernet address range 00:80:F9:81:00:00 to 00:80:F9:83:FF:FF. The format is shown in Table 6-1.

INTERRUPT REGISTERS
The system error and parity error interrupts are routed to the CPLD. These signals, per the
PCI specification, are sampled on the rising edge of the PCI clock. Since the PCI clock is
restricted to one load, SERR and PERR from the PPMC site are sampled with a 66 MHz onboard clock. These signals should be held low for a clock cycle or they will be ignored. The
following signals are routed to the appropriate MV64460 MPP pin:
• PERR and SERR are combined into a single interrupt and routed to MPP13.
• The non-maskable watchdog timer is routed to MPP18.
To control the routing of the interrupts, the CPLD implements the following enable and
pending registers.

Section 8
Serial Input/Output
The PmPPC7448 has two EIA-232 serial ports. These ports operate between 9600 and
115,200 baud. Software selects the speed and these settings are stored in non-volatile
memory. Serial port one is always routed to the Development Mezzanine Card (DMC) serial
connector as 12 volts; build options include connections to the front panel serial connector,
or the P14 connector. When routed to P14, there is the option of either EIA-232 or TTL signaling levels. Port two is routed to P14 with the same options. The Marvell MV64460 system controller provides the communication ports for the PmPPC7448. For more detailed
information on the MV64460, reference the web site http://www.marvell.com.
MULTI-PROTOCOL SERIAL CONTROLLERS (MPSC)
The MV64460 has two MPSCs with each channel supporting HDLC, BISYNC, UART, or Transparent protocols.
Signals Routing: The two MPSCs can be routed to serial port 0 and serial port 1, or not connected. These are
defined in the Main Routing register (MRR).
MPSCx Main Configuration Registers:
Each MPSC has an MPSC Main Configuration register (MMCRx) for port 0 and port 1. The
MMCRx is a 64-bit register that configures common MPSC features and is protocol independent. Each MMCRx consists of two 32-bit registers, MMCRLx (low) and MMCRHx (high).
SERIAL DMA (SDMA) CHANNELS
Two of the SDMA channels support data movement between the MPSCs and memory buffers on the MV64460. Each channel consists of a DMA engine for receiving and one for transmitting. The SDMA uses a linked chain of descriptors and buffers to reduce CPU overhead.
PROGRAMMABLE BAUD RATE
The MV64460 has two programmable baud rate generators (BRG); each with five clock
inputs: BClkIn, TClk, SCLK, TSCLK, and CLKSel.
BRGx Configuration Register
When a BRG is enabled, it loads the Count Down Value (CDV) from the BRG configuration
register into its count down counter. When the counter expires (reaches zero), the BRG
clock output (BCLK) is toggled and the counter reloads.
Note: The EIA-232C specification defines a maximum rate of 20,000 bits per second over a typical 50-foot cable
(2,500 picofarads maximum load capacitance). Higher baud rates are possible, but depend specifically upon
the application, cable length, and overall signal quality.
10006757-02
PmPPC7448 User’s Manual
8-1
Serial Input/Output:
I2C Interface
BRGx Tuning Register
A baud tuning mechanism adjusts the generated clock rate to the receive clock rate. When
baud tuning is enabled, the baud tuning mechanism monitors for a start bit (for example
high-to-low transition). Once the start bit is found, the baud tuning machine measures the
bit length by counting up until the next Low-to-High transition. Then the count-up value of
the BRG is loaded into the Count Up Value (CUV) register and a maskable interrupt is generated signaling the CPU that the bit length value is available. Finally, the CPU reads the value
from the CUV and adjusts the CDV to the requested value.
I2C INTERFACE
The MV64460 has full I2C interface support, acting as both a master generating read/write
requests and as a slave responding to read/write requests. The I2C port consists of two
open drain signals—serial clock (SCL) and serial data/address (SDA).
Note: Marvell documentation refers to this as the Two-Wire Serial Interface (TWSI).
An I2C serial configuration ROM is connected to the MV64460’s I2C interface, and is disabled by default. Emerson uses the addresses in Table 8-1 for I2C devices.

Real-Time Clock
The standard real-time clock (RTC) for the PmPPC7448 is provided by an M41T00 device
from STMicroelectronics. This device has an integrated year-2000-compatible RTC, power
sense circuitry, and uses eight bytes of non-volatile RAM for the clock/calendar function.
The M41T00 is powered from the +3.3 volt rail during normal operation.
Caution: A supercapacitor on the PmPPC7448 provides backup operation in the event of a power
failure. However, if power is not reapplied within 12 hours, all data stored in non-volatile
!
RAM may be lost.

OPERATION
The M41T00 clock operates as a slave device on the serial bus. To obtain access, the RTC
implements a start condition followed by the correct slave address (D0h). Access the eight
bytes in the following order:

The M41T00 clock continually monitors the supply voltage (Vcc) for an out of tolerance
condition. If Vcc falls below switch-over voltage (Vso), the M41T00:
• Terminates an access in progress
• Resets the device address counter
• Does not recognize inputs (prevents erroneous data from being written)
At power-up, the M41T00 uses Vcc at Vso and recognizes inputs.
CLOCK OPERATION
Read the seven Clock registers one byte at a time or in a sequential block. Access the Control register (address location 7) independently. An update to the Clock registers is delayed
for 250 ms to allow the read to be completed before the update occurs. This delay does not
alter the actual clock time. The eight byte clock register sets the clock and reads the date
and time from the clock, as summarized in Table 9-1.

CPLD_TCK: Test Clock Input—this is the clock input to the boundary scan test (BST) circuitry. Some
operations occur at the rising edge, while others occur at the falling edge.
CPLD_TDI: Test Data Input—this is the serial input pin for instructions as well as test and programming
data. Data is shifted in on the rising edge of TCK.
CPLD_TDO: Test Data Output—this is the serial data output pin for instructions as well as test and programming data. Data is shifted out on the falling edge of TCK.
CPLD_TMS: Test Mode Select—this input pin provides the control signal to determine the transitions of
the TAP controller state machine. Transitions within the state machine occur at the rising
edge of TCK. Therefore, TMS must be set up before the rising edge of TCK. TMS is evaluated
on the rising edge of TCK.
DMC JUMPERS (JP1)
There are a total of five jumper pairs on the DMC. Pins 9 and 10 are spare jumper posts. See

Section 11
Monitor
The PmPPC7448 monitor is based on the Universal Boot (U-Boot) program, available under
the GNU General Public License (GPL). For instructions on how to obtain the source code for
this GPL program, please visit http://www.emersonembeddedcomputing.com, send an email to support@artesyncp.com, or call Emerson at 1-800-327-1251.
This chapter describes the monitor’s basic features, operation, and configuration
sequences. This chapter also serves as a reference for the monitor commands and functions.
COMMAND-LINE FEATURES
The PmPPC7448 monitor uses a command-line interface with the following features:
Auto-Repeat: After entering a command, you can re-execute it simply by pressing the ENTER or RETURN
key.
TFTP Boot: You can use the TFTP protocol to load application images via Ethernet into the
PmPPC7448’s memory.
Auto-Boot: You can store specific boot commands in the environment to be executed automatically
after reset.
Flash Programming: You can write application images into Flash via the U-Boot command line. One megabyte at
the base of Flash is reserved for the monitor.
At power-up or after a reset, the monitor runs diagnostics and reports the results in the
start-up display, see Fig. 11-1. During the power-up sequence, the monitor configures the
board according to the environment variables (see “Environment Variables” on
page 11-22) and settings in the Board Configuration registers (see “Board Configuration
Registers” on page 7-6). If the configuration indicates that autoboot is enabled, the monitor attempts to load the application from the specified device. If the monitor is not configured for autoboot or a failure occurs during power-up, the monitor enters normal
command-line mode.

BASIC OPERATION
The PmPPC7448 monitor performs various configuration tasks upon power-up or reset.
This section describes the monitor operation during initialization of the PmPPC7448 board.
The flowchart (see Fig. 11-2) illustrates the power-up and global reset sequence (bold text
indicates environment variables).
Power-up/Reset Sequence
The PmPPC7448 monitor follows the boot sequence in Fig. 11-2 before auto-booting the
operating system or application software. At power-up or board reset, the monitor performs hardware initialization, diagnostic routines, autoboot procedures, free memory initialization, and if necessary, invokes the command-line. Note that the U-Boot monitor has
the ability to timeout while waiting for EREADY. See Table 11-2 for default configuration settings.
Prior to the console port being available, the monitor will display a four-bit hexadecimal
value on LED1 through LED4 to indicate the power-up status. In the event of a specific initialization error, the LED pattern will be displayed and the board initialization will halt. Refer
to Fig. 11-2 for the LED pattern at the various initialization steps.

POST Diagnostic Results
The PmPPC7448 Power-On Self-Test (POST) diagnostic results are stored as a 32-bit value
in I2C NVRAM at the offset 0x1DD8-0x1DDB. Each bit indicates the results of a specific test,
therefore this field can store the results of up to 32 diagnostic tests. Table 11-1 assigns the
bits to specific tests.

Monitor SDRAM Usage
U-Boot locates its stack, uninitialized data, and code in the top one megabyte of SDRAM.
The exact address varies with the amount of installed memory. U-Boot uses the area from
0x00000000 to 0x00004000 in SDRAM for the MPC7448 exception vector table and U-Boot
internal use.
Caution: Any writes to these areas can cause unpredictable operation of the monitor.

MONITOR RECOVERY AND UPDATES
This section describes how to recover and/or update the monitor, given one or more of the
following conditions:
• If there is no console output, the monitor may be corrupted and need recovering
(“Recovering the Monitor” on page 11-4).
• If the monitor still functions, but is not operating properly, then you may need to reset
the environment variables (“Resetting Environment Variables” on page 11-7).
• If you are having Ethernet problems in the monitor, you may need to set the serial
number, since the MAC address is calculated from the serial number variable.
Recovering the Monitor
First, make sure that a monitor ROM device is installed in the PLCC socket of the DMC module and the DMC module is installed on the PmPPC7448. Then, place a jumper on JP2,
across pins 3 and 4 on the DMC.

Restoring the PmPPC7448 Monitor Using the KatanaQP
To restore the PmPPC7448 monitor image from the soldered flash, the monitor image can
be copied to the KatanaQP carrier’s RAM, to the soldered flash, and finally to the socket
flash (EEPROM) via a PCI interface. The KatanaQP’s socket flash can then be removed and
placed on any PmPPC7448’s DMC. Follow the instructions below to copy the monitor
image from the PmPPC7448 to the socket flash on the KatanaQP.
Note: This example shows how to port linux kernel images in the monitor, however copying a monitor image uses
the same steps.
Note: This example assumes that the os kernel in the KatanaQP already sits at flash memory starting at
0xe8100000. The size of the data chunk is 1.6MB <2MB.
1 Firmly insert the PmPPC7448 on one of the four PMC slots on the KatanaQP.
2 Setup two console terminals with the first for the KatanaQP console and the second for the
PmPPC7448 console.
3 Boot the KatanaQP and bring it to the monitor prompt.
4 Enter showpci at the command prompt.

The PmPPC7448 monitor image has been successfully copied to the KatanaQP’s soldered flash. Now
from the KatanaQP console, copy the image to the socket flash using the following steps.
1 Toggle the memory map to see the socket flash window.
KatanaQp(1.0.a) => setenv write_enable_socket on
KatanaQp(1.0.a) => reset
KatanaQp(1.0.a) => memmap
2 Look for the entrance address of the socket flash.
Note: There will be two windows that map the same socket flash to the memory. Look for the one with “WE”. This
is the region to write to. Or enter flinfo to find the writable socket flash memory map in bank 1.
3 Treat the socket flash like soldered flash and perform the monitor image rewrite:
KatanaQp(1.0.a) => protect off [address range]
Note: The minimum range is a sector.
KatanaQp(1.0.a) => cp [src_addr] [des_addr] [byte_length]
KatanaQp(1.0.a) => protect on [address range]
The monitor image has been successfully copied from the KatanaQP’s soldered flash to the socket
flash. The socket flash can now be removed and placed on any PmPPC7448’s DMC.

These message stream settings cannot be saved and will revert back to serial on reset. To
enable NetConsole on reset, the appropriate commands must be placed in either the
bootcmd or preboot environment variable. To be able to skip the autoboot process using
NetConsole, it makes sense to enable NetConsole in preboot:

MONITOR COMMAND REFERENCE
This section describes the syntax and typographic conventions for the PmPPC7448 monitor
commands. Subsequent sections in this chapter describe individual commands, which fall
into the following categories: boot, memory, Flash, environment variables, test, and other
commands.

Monitor:
Boot Commands
Command Syntax
The monitor uses the following basic command syntax:
<Command> <argument 1> <argument 2> <argument 3>
• The command line accepts three different argument formats: string, numeric, and
symbolic. All command arguments must be separated by spaces with the exception of
argument flags, which are described below.
• Monitor commands that expect numeric arguments assume a hexadecimal base.
• All monitor commands are case sensitive.
• Some commands accept flag arguments. A flag argument is a single character that
begins with a period (.). There is no white space between an argument flag and a
command. For example, md.b 80000 is a valid monitor command, while md .b 80000
is not.
• Some commands may be abbreviated by typing only the first few characters that
uniquely identify the command. For example, you can type h instead of help. However,
commands cannot be abbreviated when accessing on-line help. You must type help and
the full command name.
Command Help
Access the monitor online help for each command by typing help <command>. The full
command name must be entered to access the online help.
Typographic Conventions
In the following command descriptions, Courier New font is used to show the command
format. Square brackets [] enclose optional arguments, and Italic type indicates that you
must substitute your own selection for the italicized text.
BOOT COMMANDS
The boot commands provide facilities for booting application programs and operating systems from various devices.
bootd
Execute the command stored in the “bootcmd” environment variable.

Boot Commands
bootelf
The bootelf command boots from an ELF image in memory, where address is the load
address of the ELF image.
DEFINITION:
bootelf [address]
bootm
The bootm command boots an application image stored in memory, passing any entered
arguments to the called application. When booting a Linux kernel, arg can be the address of
an initrd image. If addr is not specified, the environment variable loadaddr is used as the
default.
DEFINITION:
bootm [addr [arg …]]
bootp
The bootp command boots an image via a network connection using the BootP/TFTP protocol. If loadaddress or bootfilename is not specified, the environment variables loadaddr
and bootfile are used as the default.
DEFINITION:
bootp [loadAddress] [bootfilename]
bootv
The bootv command checks the checksum on the primary image (in Flash) and boots it, if
valid. If it is not valid, it checks the checksum on the secondary image (in Flash) and boots it,
if valid. If neither checksum is valid, the command returns back to the monitor prompt.
DEFINITION: Verify bootup.
bootv
Write image to Flash and update NVRAM.
bootv <primary|secondary> write <source> <dest> <size>
Update NVRAM based on image already in Flash.
bootv <primary|secondary> update <source> <size>
Check validity of images in Flash.
bootv <primary|secondary> check
bootvx

Memory Commands
dhcp
The dhcp command invokes a Dynamic Host Configuration Protocol (DHCP) client to
obtain IP and boot parameters by sending out a DHCP request and waiting for a response
from a server.
DEFINITION:
dhcp [load address] [bootfilename]
rarpboot
The rarpboot command boots an image via a network connection using the RARP/TFTP
protocol. If loadaddress or bootfilename is not specified, the environment variables loadaddr
and bootfile are used as the default.
DEFINITION:
rarpboot [loadAddress] [bootfilename]
tftpboot
The tftpboot command loads an image via a network connection using the TFTP protocol.
The environment variable’s ipaddr and serverip are used as additional parameters to this
command. If loadaddress or bootfilename is not specified, the environment variables
loadaddr and bootfile are used as the default.
The port used is defined by the ethport environment variable. If all is selected for ethport,
the TFTP process will cycle through each port until a connection is found or all ports have
failed.
DEFINITION:
tftpboot [loadAddress] [bootfilename]
MEMORY COMMANDS
The memory commands allow you to manipulate specific regions of memory. For some
memory commands, the data size is determined by the following flags:
DEFINITION: The flag .b is for data in 8-bit bytes.
DEFINITION: The flag .w is for data in 16-bit words.
DEFINITION: The flag .l is for data in 32-bit long words.
These flags are optional arguments and describe the objects on which the command operates. If you do not specify a flag, memory commands default to 32-bit long words. Numeric
arguments are in hexadecimal.
cmp
The cmp command compares count objects between addr1 and addr2. Any differences are
displayed on the console display.
10006757-02
PmPPC7448 User’s Manual
11-11
Monitor:
Memory Commands
DEFINITION:
cmp [.b, .w, .l] addr1 addr2 count
cp
The cp command copies count objects located at the source address to the target address.
If the target address is located in the range of the Flash device, it will program the Flash with
count objects from the source address. The cp command does not erase the Flash region
prior to copying the data. The Flash region must be manually erased using the erase command prior to using the cp command.
DEFINITION:
cp [.b, .w, .l] source target count
EXAMPLE: In this example, the cp command is used to copy 0x1000, 32-bit values from address
0x100000 to address 0x80000.
=> cp 100000 80000 1000
find
The find command searches from base_addr to top_addr looking for pattern. For the find
command to work properly, the size of pattern must match the size of the object flag. The a option searches for the absence of the specified pattern.
DEFINITION:
find [.b, .w, .l] [-a] base_addr top_addr pattern
EXAMPLE: In this example, the find command is used to search for the 32-bit pattern 0x12345678 in
the address range starting at 0x40000, and ending at 0x80000.
=> find.1 40000 80000 12345678
Searching from 0x00040000 to 0x00080000
Match found: data = 0x12345678 Adrs = 0x00050a6c

md
The command md displays the contents of memory starting at address. The number of
objects displayed can be defined by an optional third argument, # of objects. The memory’s
numerical value and its ASCII equivalent is displayed.
DEFINITION:
md [.b, .w, .l] address [# of objects]
EXAMPLE: In this example, the md command is used to display thirty-two 16-bit words starting at the
physical address 0x80000.

Memory Commands
mm
The mm command modifies memory one object at a time. Once started, the command line
prompts for a new value at the starting address. After a new value is entered, pressing
ENTER auto-increments the address to the next location. Pressing ENTER without entering
a new value leaves the original value for that address unchanged. To exit the mm command, enter a non-valid hexadecimal value (such as x) followed by ENTER.
DEFINITION:
mm [.b, .w, .l] address
EXAMPLE: In this example, the mm command is used to write random 8-bit data starting at the physical address 0x80000.
=> mm.b 80000
00080000: ff ? 12
00080001: ff ? 23

nm
The nm command modifies a single object repeatedly. Once started, the command line
prompts for a new value at the selected address. After a new value is entered, pressing
ENTER modifies the value in memory and then the new value is displayed. The command
line then prompts for a new value to be written at the same address. Pressing ENTER without entering a new value leaves the original value unchanged. To exit the nm command,
enter a non-valid hexadecimal value (such as x) followed by ENTER.
DEFINITION:
nm [.b, .w, .l] address
mw
The command mw writes value to memory starting at address. The number of objects modified can be defined by an optional fourth argument, count.
DEFINITION:
mw [.b, .w, .l] address value [count]
EXAMPLE: In this example, the mw command is used to write the value 0xabba three times starting at
the physical address 0x80000.

Variable:1
Description: (continued)
pci_memsize
Sets the amount of SDRAM memory made available on the PCI bus. This
parameter is applicable when the board is either the Monarch or nonMonarch. The minimum setting is 16 megabytes. If not set, 128 MB of
SDRAM are available over PCI.
Valid options: all, size in hex (0x8000000=128 MB)
sec_bootargs
Sets the boot arguments that are passed into the secondary application
images when using the bootv command. If not defined, the bootv will
pass the bootargs configuration parameters into the secondary
application image.
1. The moninit command does not initialize these variables. Each parameter is only defined if a change from
the default setting is desired and is not defined after initialization of the configuration variables.
TROUBLESHOOTING
To bypass the full board initialization sequence, attach a terminal to the console located on
the front of the module. Configure the terminal parameters to be:
9600 bps, no parity, 8 data bits, 1 stop bit
Reset the module while holding down the ‘s’ key. Pressing the ‘s’ key forces a configuration
based on default environment variables.
DOWNLOAD FORMATS
The PmPPC7448 monitor supports binary and Motorola S-Record download formats, as
described in the following sections.
Binary
The binary download format consists of two parts:
• Magic number (which is 0x12345670) + number of sections
• Information for each section including: the load address (unsigned long), the section
size (unsigned long), and a checksum (unsigned long) that is the long-word sum of the
memory bytes of the data section
Motorola S-Record
S-Record download uses the standard Motorola S-Record format. This includes load
address, section size, and checksum all embedded in an ASCII file.
