IWR6843: Die Id

Annie Liu

Part Number: IWR6843


Hi Team,

The customer obtains the die id in xwr1642 like this:

retVal = rlGetRfDieId(RL_DEVICE_MAP_INTERNAL_BSS, &dieIdStatus);

RL_DEVICE_MAP_INTERNAL_BSS corresponds to the mapping of 1642, he would like to know which is the mapping of 6843?

Thanks,
Annie

    Hi Annie,

    The API is used exactly the same way on 6843.

    Example Usage of the above API:  The mmw demo provides the "version" command which you can run on the CLI to get this information. To understand the implementation, please refer to the function CLI_MMWaveVersion() in C:\ti\mmwave_sdk_03_04_00_03\packages\ti\utils\cli\src. I have pasted the exact code snippet from this function below:

        /* Get the die ID: */
    retVal = rlGetRfDieId(RL_DEVICE_MAP_INTERNAL_BSS, &dieId);
    if (retVal < 0)
    {
        CLI_write ("Error: Unable to get the device die ID from mmWave link [Error %d]\n", retVal);
        return 0;
    }

    CLI_write ("Lot number              : %d\n", dieId.lotNo);
    CLI_write ("Wafer number            : %d\n", dieId.waferNo);
    CLI_write ("Die coordinates in wafer: X = %d, Y = %d\n",
               dieId.devX, dieId.devY);

    Thanks
