IWR1843BOOST: Radar Software Crash in DSS with Multiple Objects (MRR Lab)

I'm facing a software crash issue with our radar system in the MRR lab. Here's the breakdown:

• FPS Dependency: As discussed in this thread the radar's frame rate (FPS) depends on the SUBFRAME_MRR_PERIODICITY_VAL parameter.
• Current Configuration: It is set to 60ms, achieving a desirable 16.67 FPS.
• Crash with Multiple Objects:  The software crashes in the DSS (specifically in the dss_main.c file) after a few seconds when multiple objects are present within the radar's field of view (FOV). {Testing was conducted in our basement with multiple objects placed in front of the radar. This behavior was not observed during lab testing with a limited number of objects.} The crash occurs at line 253 of dss_main.c.

/* Check if the previous frame has been completely processed. */
MmwDemo_dssAssert(dataPathObj->chirpCount != 0);

• Reduce Maximum Objects: I understand increasing SUBFRAME_MRR_PERIODICITY_VAL can overcome this crash but this would decrease my FPS. Alternatively, could reducing the MRR_MAX_OBJ_OUT value (currently at 200) help avoid crashes while maintaining the 60ms periodicity?

• I'd appreciate further insights on :
  • Are there other ways to prevent software crashes besides adjusting SUBFRAME_MRR_PERIODICITY_VAL or MRR_MAX_OBJ_OUT ? Are there potential optimizations within the DSS code that could improve performance with a higher object count?

Thanks in advance for your help!
