IWRL6432: The reset value of HWA_PARAM_MEM

Shinichiro Tamagawa
Prodigy 20 points
Part Number: IWRL6432

Tool/software:

I understand that there are two main types of registers that need to be configured to use the HWA: HWA_CFG and HWA_PARAM_MEM.

The HWA_CFG register is described in section 10.4(HWA_CFG Registers)of the TRM, where its reset value is explicitly defined.
Whereas, while the layout of HWA_PARAM_MEM is explained in section 10.1.6(Appendix), there is no information provided regarding its reset value.

Could you please provide the reset value for HWA_PARAM_MEM?

    Hi, there:

    For AWR device, boot loader may initialize some of the memory to zero.  For IWR device, the memory is not initialized.  The users will need to take responsibility to initialize/program these memories. 

    For the HWA parameter sets configuration, the users will need to program them depending on how they plan to use it.  The customer will also program in the common configuration how to use these parameter sets.  

    For example, users may use the first 4 parameter sets for range FFT, the next 6 for Doppler FFT, and the next 4 for angle estimation.   Then in the range FFT module, users will program the common configuration to use the first 4 parameter set,  and etc.    

    Best,
