    Hi Ken,

    I do not find the connections provided before modifications to be correct. Pin 56,58, 50, 52 is correct is per the EVM schematics but pin 38,40,32 and 34 are NC pins. So, it is unclear as to where you have picked us the pin mapping for AWR2944 EVM kit. Can you clarify this?

    Thanks,

    Pradipta.
