Problems with IPC examples

Bernd Erbe
Expert 2065 points


Hello,

I've got a problem with both IPC examples (MessageQ and Notify) running them in CCS. Setup is as follows:

CCS Version 5.1, IPC Version 1.23.05.40, SYS/Bios Version 6.32.05.54, Using TMDXEVM6678 Rev. 1.0 on Windows 7

Compiling both examples is okay.

Loading and starting the Notify example on one ore more cores is okay, also the first output is shown:

[C66xx_0] main: MultiProc id = 0
[C66xx_0] main: MultiProc name = CORE0
[C66xx_1] main: MultiProc id = 1
[C66xx_1] main: MultiProc name = CORE1

But the example doesn't terminate and no output from the tsk0_func is printed. Pausing the cores, they are in functions like:

-SharedRegion_getEntry
-Ipc_procSyncStart
-Ipc_attach

Behaviour on simulator is the same. Starting the MessageQ example, it is also the same behaviour, but the output seen above is not shown.

I think it's a configuration problem with IPC, but I don't enough to debug this problem.

 

Thanks for help,

Best Regards,

Bernd

    Hi Bernd,

    If you didn't make any modification on the original source code and cfg script, the program should run without problem.

    And do you run the program on all 8 cores? I see you only paste the console output on 2 cores.

    If not, the IPC_attach will suspend, because the Ipc.procSync = Ipc.ProcSync_ALL; is stated in cfg, so you should run all 8 cores in order to finish attaching.

    Hi Allen,

    very nice, that was the problem. I thought I tried it, but for sure I haven't.

    Thanks for the help,
