IWR1642BOOST: mmWave open configuration failed [Error code -203554190]

Part Number: IWR1642BOOST

I am working on a slightly modified version of the high_accuracy project for IWR1642Boost v2, using the v2 SDK and the 2.4.0 Industrial Toolbox.

When trying to run the project it looks like the commands are received successfully but the mmWave open fails with the following error:

Error: MMWDemoMSS mmWave open configuration failed [Error code -203554190]

Can you help me understand what might be going wrong? I don't know what that error code means. The full debug output is below.

    FYI - here are the commands that were issued:

    dfeDataOutputMode 1
    channelCfg 1 1 0
    adcCfg 2 1
    adcbufCfg 0 1 1 1
    profileCfg 0 77 7 7 114.4 0 0 33.71 1 512 5000 0 0 48

    Hello Shaun,

    For SDK v2.0 you need to use

    'lowPower 0 1'  CLI command. This will resolve the issue.

    Let me tell you how to decode this error value to find out the cause of it.

    In mmWave error code in [31:16] bits of the final error value. So find out mmWave layer error you need to do a right shift by 16bits on given error value.

    -203554190>>16 = -3106 [MMWAVE_EPOWERCFG]

    So the error value maps to below code snippet of mmwave_link.c file

    /****************************************************************************************
    * Set the low power mode configuration:
    ****************************************************************************************/
    retVal = rlSetLowPowerModeConfig(RL_DEVICE_MAP_INTERNAL_BSS, &ptrMMWaveMCB->openCfg.lowPowerMode);
    if (retVal != RL_RET_CODE_OK)
    {
    /* Error: Set the Low power configuration failed */
    *errCode = MMWave_encodeError (MMWave_ErrorLevel_ERROR, MMWAVE_EPOWERCFG, retVal);
    retVal = MINUS_ONE;
    goto exit;
    }
