IWR6843: RF self-calibration issue

Hi,

We are working on IWR6843 product design, and we are testing the self-calibration functions by using mmWave studio on IWR6843 EVB, however it doesn't work. There are some issues situations below

1.TX power and RX gain didn't execute in boot time.

2. Got fail results on most of testing items except APLL, VCO and LO.

Both AWR1843 and AWR1643 has no issue with same testing procedures, and i didn't find any issue on IWR6843 errata, pls. provide suggestion how to perform self-calibration on IWR6843.

3. The APLL, VCO and LO calibration still works, we got calibration results as below, how to explain these data ? is there mapping doc. for reference ?

thanks.
