AWR2243-2X-CAS-EVM: Known Issues

Hello,

I have a question about known issues with the AWR2243-2X-CAS-EVM.

Currently, the chirp design is limited to 192 ADC samples, 256 chirps, and 8 channels, and no other configurations have been tested.

I expect to test other chirp designs in the future, but I wonder what the maximum ADC sample and chirp number values ​​are that can be set in the chirp design.

Regards,
Tsuda

    This depends on the size of DSS_L3 of AM273x. You can check if the Compressed 1D FFT, detection matrix etc. which are outputs of the processing chain, will fit in the DSS_L3 of AM273x. You should also consider if you have sufficient memory to store the intermediate results of the doppler processing on DSS_L2 of AM273x. This is not the AWR2243 Front-end limitation, rather it's AM273x memory constraints.
