IWR1642BOOST: Failed to set Complex 2x with mmwavelink

Hello,

I'm trying to capture raw data from IWR1642+DCA1000EVM with my own application rather than mmWave Studio.

I modified mmwavelink_example in C:\ti\mmwave_dfp_01_02_05_01\ti\example\mmwavelink_example to apply on IWR1642 according to this thread https://e2e.ti.com/support/sensors/f/1023/p/826017/3055751#3055751.

If I'm not making it wrong, the sensor's configuration parameters should be specified manually in mmwaveconfig.txt in that directory.

However, when I tried to set the field adcFmt to 2, which corresponds to Complex 2x mode, the application failed with error code -1(mmWaveLink Protocol error).

Besides, the adcFormat field is also set to 2.

Can anyone tell me what have I missed?

Thanks.
