Agreement (EULA) file in the release.
-------------------------Known Issues and Limitations:
1. Seagate 7200RPM, 80G SATA hard disk can only work at 1.5Gbps and can
not work
stable at 3Gbps due to hardware board issue.
Workaround: Set the hard disk to 1.5Gbps operation or use Hitachi
7200RPM, 160G
STAT hard disk
Revision Plan: The board will be shipped with Hitachi 7200RPM, 160G
STAT hard disk.
2. U-Boot displays "Invalid ID (ff ff ff ff)" at start up if the board
doesn't
have a correct ID in EEPROM.
Workaround: Set the following command to U-Boot:
=> mac id NXID
=> mac save
Revision Plan: It depends on hardware board manufacturing process.
3. When running iperf command line as:
iperf -c 192.168.1.10 -V -i5 -P10 -m -M 64 -t 20 -w 8k
Iperf hangs on eTSEC and the board needs to be rebooted. Running the
same command
to test PCI or PCIe Ethernet works fine. Also, when running just the
default
command "iperf -c 192.168.1.10" without any arguments for eTSEC this
also works
fine. The arguments -M and -P could lead to hang with default applying
the below
two patches in the BSP:
Patch26: 0017-SKB-recycling-version-1-1-4.patch
Patch27: 0004--gianfar-Fastroute-patch.patch
These two patches can improve the IP-Forwarding performance
significantly.
Workaround: when test iperf, comment the following two lines in the
spec file:
litb/dist/lfs-5.1/kernel/kernel-2.6.28-mpc8536ds.spec.in
%patch26 -p1
%patch27 -p1
But when testing the IP-Forward, please use the default spec file by
not comment
these two lines.
Revision plan: Will be fixed in the final release.
4. The performance test for the USB2.0 Host operation for a USB2.0 Udisk connected
to the port using the open source performance tools iozone and
bonnie++, the write
performance is lower than the USB2.0 Hi-Speed specification and also
depends on
the brand of the U-disk. For example, it can arrive at 9.3MBps on Nova
4GB U-Disk
and at 6.4MBps on SanDisk 2GB U-Disk.
Workaround: Use different types of USB disk or device
Revision plan: Will be fixed in the final release for the performance
issue.
5. When SD boot at 1500/500/667, some board can not correctly boot up.
Workaround: please change the DDR frequency to 600MHz.
6. For other known issues and limitations, please refer to specific
User's Manual
found in help/documents/html/ of this DVD image.
-------------------------Helpful Tips:
1. Before using ghost to restore SD card, please change the option as
following:
1/ Start ghost.
2/ Select "Options" item in the main menu.
3/ Select "Image/Tape" tab.
4/ On the top half of the page, select "Image Disk" option, then click
the "Accept"
button to close the window.
