AWR1843BOOST: Error Code: Out of L3 RAM during detection matrix allocation - Demo lab

AWR1642BOOST: Impact of reducing L3 RAM space if my usecase required only reading point cloud (x, y, z and velocity)

Hi, 

I'm using the out-of-the-box demo to access position and velocity data. I need to integrate application code that utilizes this position and velocity information, which requires additional .bss DATA and code memory than specified in the default case.  I've noticed that by modifying the C:\ti\mmwave_sdk_03_06_02_00-LTS\packages\ti\common\mmwave_sdk_xwr16xx.mak and the r4f linker file, I can increase the .bss and code memory, but this will decrease the memory available for shared L3 RAM.

I believe L3 RAM is used to store raw ADC data.

What are the implications of reducing L3 memory if my use case is solely focused on reading position data and not ADC data?

Thanks 

Regards

Gayatri
