IWR6843: IWR6843/DCA 1000 not working with mmwave studio 2.1.0.0

Part Number: IWR6843

Hi,

With mmwave studio 2.0.0.2, i am able to use DCA1000 and iwr6843 ISK board to capture adc raw data, but when i try to upgrade to mmwave studio 2.1.0.0, there is always an issue after press "RF Power-Up" button, some error message listed as below. please advise how to fix this issue? Or, is it OK to use mmwave studio version (2.0.0.2) for development instead of 2.1.0.0? Thanks!
