IWR6843AOP: Debug: Init Calibration Status = 0x1ffe

Part Number: IWR6843AOP

Hi,

I encountered this calibration status using my custom board based on the IWR6843AOP and hard coded config. What does it exactly mean and how to repair it?

Thank you for your help,

  • Hello Adam.

    This error usually occurs if there is an issue with your configuration parameters.  However, it looks like your configuration is the same that is provided in the example.  Did you make any changes to the example code or is the only thing different in your set up the board?

    Sincerely,

    Santosh
