CCS: Understanding error codes

Other Parts Discussed in Thread: IWR6843, AWR1843, AWR1642

Tool/software: Code Composer Studio

Hi guys,

I am making some application with your radar sensors. I have tried to port the code from AWR1843 to IWR6843, and the code builds and runs on the system, but there are some issues. The main issue is that after I load the cfg over UART, and dss subsystem starts initiating datapath, i get this console output:

Error: MMWDemoDSS mmWave Start failed [Error code -204602898]
Debug: MMWDemoDSS Data Path start failed with Error[-1]
Debug: MMWDemoDSS Data path exit

At the moment, i have no idea how to understand an error code, is there some description in your documentation about error codes? If there is, could you give me some instructions on how to find it? 

Kind regards,

Aleksa

    Hi guys,

    I have found an error code, it's:

    RL_RET_CODE_RX_GAIN_BOOT_CAL_NOT_DONE.

    It happens here:

    But this part of the code seems fine. Do you have an idea where this error could have come from? 

    Obviously it has something to do with calibration of rx antenna. In your instructions for moving from awr1642 to iwr6843 you have given these two lines:

    gMmwMssMCB.cfg.openCfg.freqLimitLow = 0U;
    gMmwMssMCB.cfg.openCfg.freqLimitHigh = 0U;

    These are calibration frequencies. Could this be wrong? What are these values?

    Kind regards, 

    Aleksa

    Hi Aleksa,

    Are you migrating from AWR1642 to IWR6843?

    And the frequency limit for AWR1642 should be 

    gMmwMssMCB.cfg.openCfg.freqLimitLow = 760U;
    gMmwMssMCB.cfg.openCfg.freqLimitHigh = 810U;

    And for calibration error : make sure that custom calibrationis disabled and all the Rx channels are enabled (gMmwMCB.cfg.openCfg.chCfg.rxChannelEn)

    gMmwMCB.cfg.openCfg.useCustomCalibration        = false;
