IWR1642BOOST: adcbufCfg command doesn't respond in occupancy detection demo

Hi,

I am trying flashed to run "lab0003_occupancy_detection" binary in IWR1642.
To configure the device using serial port I give following commands

mmwDemo:/>sensorStop
Done
mmwDemo:/>flushCfg
Done
mmwDemo:/>dfeDataOutputMode 1
Done
mmwDemo:/>channelCfg 15 3 0
Done
mmwDemo:/>adcCfg 2 1
Done
mmwDemo:/>adcbufCfg -1 0 0 1 1

I get the acknowledgement up till "adcCfg" command.
As soon as I enter "adcbufCfg" command as shown above, the device hangs and doesn't respond.

Since I am using IWR1642 evm instead of AWR1642 evm.Please confirm If I can use AWR1642 binary in IWR1642 evm?
If yes, please suggest the method to resolve above issue.

Thanks in advance
Vikas.
