Failed Shutdown or Target not responding procedure
1, If the target will not close from RT-Lab and there is a Controller exe running not
allowing you to close the model. Close Controller Window
Note:
You can open Controller.exe this from lower toolbar:
If the Controller does not open, right click on RT icon on System Tray and Select
Display Controller(s)
Do not close out controller window while model is running. This will process
handles the interaction between the model running on the QNX target and the
LabVIEW API interface.

2. Verify that there are no longer Controller.exe processes running. From Windows Taks
Manager, Select Processes Tab. Highlight Controller.exe processes and Select: End
Process.
3. On OPAL-RT target, manually flip the RESET switch. Wait 5 minutes for the target
to reboot or verify that it is up by pinging the target, so that you can re-load the FS3
model.
4. Verify that RT-Lab MetaController is running on the Taskbar:

Kill Processes running on QNX target
Question
How do you kill a process running on a QNX target from HOST PC or Target PC? The
RT-Lab Main Control mentions that I cannot load another model on the QNX target
because I already have 1 model running.
Answer
1.Telnet into QNX target (Or log into QNX target directly using login: root)
Goto Start Menu > Run.
Enter telnet 192.168.10.101
 This is the IP address of your QNX target
* Telnet:
2. Telnet session will open up. This is your telnet login into QNX on your target.
Login: root

* telnet window:
3. In command line, Enter ps –A to show processes that are currently running on the
QNX target:
# ps -A

processes:
4. To stop a certain process like a model that may still be running, enter kill [PID #]
For example:
#kill 22532123

Keith Kukolich
This command will kill the Simulink model from directory /home/rapter/main (c)/opalrt/.. that is currently running.
5. To make sure that the process stops running, enter ps –A to verify that the process has
been stopped.
#ps –A

Note: If Windows asks for user and password, user: ntuser password: ntuser.
3. You can copy, drag, and move files to the target like a normal Windows Explorer
window.
On the OPAL-RT QNX target, this directory is /home/ntuser/.

Target Management Basic Commands:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
find Searches the named directory and it"s sub-directories for files. Most
frequently called like this: find ./ -name "t*" -print Which searches the current
directory ( and all of its sub-directories ) for any files that begin with the letter "t"
and then prints them out. If you are looking for a specific filename, then replace
"t*" with "filename", and "find" will print out all incidences of this file.
ls {directory} Shows directory listing. If no "directory" is specified, "ls" prints
the names of the files in the current directory. The Command : ls –lo /usr/opal-rt
gives you the versions of RT-LAB installed on your target
cp {filename(s)}{path} Copies files from one directory/filename to another. "cp
f1 f2" makes a file "f2" identical to "f1". "cp *.c src/" copies all files that end in
".c" into the "src" subdirectory.
rm filename(s) Removes files. Careful with this one - it is irreversible. It is
usually aliased ( in a user"s .cshrc file ) to "rm -i" which insures that "rm" asks
you if you are sure that you want to remove the named file.
mkdir dirname Makes a sub-directory named "dirname" in the current directory.
pwd Shows current working directory path.
mv Moves files
uname –a Tells you the QNX version of your target
pci –v | less Tells you all the pci card in your target system
pidin info Tells you information about your computer’s memory and processor
speed
chmod {options} Changes the permission modes of a file.
vi: Runs the screen oriented text editor named "vi". If a filename is specified, you
will be editing that file. Type "[ESC]:q!" to exit without making any changes.
You could check basic VI commands on
http://www.la.unm.edu/computer/docs/basic_vi.shtml#modes
ifconfig –a Gives your network setting information. If you want to change the IP
address of your target, you need to edit the net.cfg file located in the etc directory
shutdown –f reboots QNX target
shutdown –fb shutdown QNX target
