AWR2243: HW_VARIANT format

Antonio Puglielli

Part Number: AWR2243
Other Parts Discussed in Thread: AWR1243,

Hello,

In AWR_MSSVERSION_SB, there is a field for hw_variant. Can you please describe the possible values and interpretation of this field? I assume that this can distinguish between AWR1243/2243/2243P, is that correct?

Thanks,
Antonio

    Hi Antonio,

    This field is to mainly distinguish b/w difference AWR device and that sample ROM version (ES).

    There are different variants of above said devices 1243/2243/2243P, hw_variant would be different for those.

    Do you find difficulty with any specific device variant you have?

    Regards,

    Jitendra

    Hi Jitendra,

    Thanks for the info. I was asking because we have some AWR2243 ES1.0 and ES1.1 and noticed they have different HW_VARIANT field. I was hoping to use this field to identify which chip is which as we have prototypes using both versions. Can you just document the possible values for this field?

    Thanks,
    Antonio

    Hi Antonio,

    If you follow mmwave DFP example, where it distinguish b/w AWR2243 ES1.0 and ES1.1

    C:\ti\mmwave_dfp_02_02_03_01\ti\example\mmWaveLink_SingleChip_Example\mmw_example.c


        retVal = rlDeviceGetMssVersion(deviceMap, &mssFwVer);
        if ((mssFwVer.fwBuild == 1) && (mssFwVer.fwDebug == 7))
        {
            gMmwaveSensorEs1_1 = AWR2243_ES1_1;
        }
        else
        {
            gMmwaveSensorEs1_1 = AWR2243_ES1_0;
        }
