AWR1243BOOST: AWR1243BOOST: DataCapturedemo_xWR.lua hangs MSS FW Download failure

I have the same troubles as described in 
https://e2e.ti.com/support/sensors/f/1023/t/825105

i'm launch AWR1243BOOST with DCA1000 board.

then i try to launch script:
ti\mmwave_studio_02_01_01_00\mmWaveStudio\Scripts\DataCaptureDemo_xWR.lua
and have error with programming MSS after programming BSS.
meanwile BSS version cleared to zeros.

i tried with older versions of mmwave studio without success.
