IWR6843: The heartrate and breathrate buffers aren't getting updated while running the Vital Signs demo

Part Number: IWR6843

Hello,

I am running the dss and mss codes of the Vital signs demo on Code Composer Studio. I have put breakpoints in the mss and dss files as shown in the below snapshot.

1)I put a breakpoint in the beginning of MmwDemo_interFrameProcessing definition in dss_data_path.c and the same function's call in dss_main.c. When I try to run this code for sometime and pause it, the values of the buffers storing data processed is 0 and doesn't get updated. As per my understanding the buffers pVitalSigns_Breath_CircularBuffer and pVitalSigns_Heart_CircularBuffer should contained the values post filtering using Biquad Cascade IIR filter so the data in the buffer cannot be zero.

2)The other issue I observed is that as soon as the code reached the call of the function MmwDemo_interFrameProcessing , it threw an assertion failure which is shown in the snapshot below.

What could possibly be the reason for both the issues and how can it be fixed?

Thanks,

Anjali
