IWR6843ISK: Debugging Issues with IWR6843

Hi all,

I’m currently experiencing issues while debugging the IWR6843ISK + MMWAVEICBOOST setup.

I’m working with the “68xx Vital Signs” module from Industrial Toolbox 4.12.1, extending its functionality for further development.

However, when I run the code in debug mode, I encounter an assertion failure caused by a deadline miss.

The log shows as:

C674X_0: Debug: MMWDemoDSS mmWave Control Initialization succeeded

Cortex_R4_0: **********************************************

Cortex_R4_0: Debug: Launching the Vital-Signs Monitoring Demo

C674X_0: xdc.runtime.Error.raise: terminating execution

The code snippet causing the issue is:

    /* Check if previous frame processing has completed */
    if (gMmwDssMCB.dataPathContext.interFrameProcToken != 0)
    {
        MmwDemo_triggerDss2MssISR(MMWDEMO_DSS2MSS_FRAME_PROC_DEADLINE_MISS_EXCEPTION);
        DebugP_assert(0);
    }

To reproduce the issue, I follow these steps:

1. Run the DSS module.

2. Run the MSS module.

3. Send the CFG file through the CLI.

At this point, logging shows assertion failure due to a deadline miss, after receiving "sensorStart."

Interestingly, this problem only appears when running in debug mode. When the code is executed in normal (non-debug) mode, everything works without errors.

Has anyone encountered this behavior before or found a way to resolve it?
