Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Hello,ti's engineer:

I use AWR1843 to develop MRR demo.And i use our waveform configuration parameter as follow:

S 4.39MHz/us Fs 6.25MHz

T 89us Tv 82us rampendtime 86us idle time 3us

B 360MHz

Chirp num 256

numAdcSamples 512

However, BSS does not seem to be working.Is there any limitation on waveform parameters?

My usage scenario is SDK3.5.0.4,lab0007_medium_range_radar,CCS10.

Thanks a lot,

Bryant

Hi,

The MRR/USRR demo supports two configurations (see below) which one are you trying to update.

The MRR/USRR is highly optimized for these configurations. Therefore there are limitations on changing the number of ADC samples and frames

If you increase one of this parameters, this will result in increasing required memory and the demo will not work.

MRR - Beamforming

USRR - MIMO

Hi，

Now i do not use usrr，only use one subframe such as MRR，and also do not use slow chirp only use 256 fast chirp.I caculate the memory is enough.

The other parameters are described above. Will BSS not work with this configuration？

Thanks a lot

The configuration looks fine.

Did you get any error message from BSS?

How do you know that the root cause is the BSS?

Thank you
