Hi,

mmWave SDK : 01_02_00_05

Application: SRR

I want to debug DSS by using MmwDemo_dssAssert(0).

When I call it in DSS, I suppose I can get some message like "DSS Exception: %s, line %d."

But when I called it on DSS, I cannot get any message in MSS.

SRR_DSS_DataPathOutputLogging(dataPathObj);
MmwDemo_dssAssert(0);

Do you have any idea that why we cannot get message from DSS by mailbox?

Thanks

Hi,

Can you please provide us more information about what you are trying to debug?

Usually, if an exception occurs, the code running on DSS will crash because it is no longer able to meet the real time deadlines imposed by the framework.

Thank you
Cesar

Hi Cesar,

if we got exception, how do we restart the MSS and DSS?

Thanks

If you simply call the assert macro, the processor will immediately stop. You would need to write to the mailbox prior to doing an assert. The only way to restart is to reset the processor. If you are doing CCS debugging, this is not the most efficient means to debug.
