AM5728: Whole DSP (TI RTOS App) execution stops after kernel log: omap_hwmod: mmu0_dsp1: _wait_target_disable failed

Hi Raj,

Can you please share the complete logs from linux?

Hi Parth,

           Here is the log:

After the above highlighted log in bold, the DSP execution stops.

Hi Raj, 

From the logs I don't see any reason for DSP to halt. Are you using the application from SDK or is it a custom application? Is there a way I can reproduce the issue on my end?

Regards,

Parth

Hi Parth,

           We are using a custom application. If you want to reproduce the same issue try following simple code:

Diags_setMask("Server+F");

/* enable some log events */
Diags_setMask(MODULE_NAME"+EXF");

while(1)
{
sprintf(sbuf, "Hello world %d", count++);
Log_print0(Diags_INFO, sbuf);
Task_sleep(500);
}

I tried printing "Hello world" with an incrementing count value for every 500 ms in an infinite loop. I loaded the application using remote proc from Linux and observed the /sys/kernel/debug/remoteproc/remoteproc2/trace0 buffer.

The buffer contains last print as "Hello world 19", as soon as the message:  [ 141.283574] omap_hwmod: mmu0_dsp1: _wait_target_disable failed, appears on Linux kernel debug logs it gets halted. The prints should have been infinite but it runs almost for 9 to 10 seconds and stops the DSP execution.

Please try the above code and help in this regard

Thanks and Regards

Hi Parth,

          Did you get a chance to look into this issue? Please let me know if your were able to reproduce the issue. What could be blocking the continuous execution in DSP when loading the firmware from remoteproc?

Thanks and Regards

Hi Raj,

Apologies for not following up on this.
Is this issue still open? If yes, can you please highlight the current status on the issue?
