I have doubts related to memory usage (profile config and subframe config).
1) As per these configurations, maximum memory usage will be 450*32*0.015*3= 650 KB. Is this calculation right? However I am unable to further increase the frame rate and samples per chirp. Two example profiles I tried were: (In config below I increased the chirp time, to increase the number of samples and SNR, while keeping no of frames same, in comparision to config A above.)
Changes: ADC smaples increased from 450 samples to 550 samples, and chiurp time increased from 50 us to 60 us. subframe_time increased from 50ms to 100 ms

This config is unable to throw any data on demovisualizer and following shows up
In my second attempt, I tried to increase the frames, instead of ADC to improve the SNR:
Changes w.r.t intial config that worked: increased no of frames from 32 to 48, and frame_periodicity from 50ms to 100 ms, compared to config A)

However still the same error shows up:
If my memory calculations are right, I am well within allowable range of 1024 kb. What may I be doing wrong, in that case?
