Hi Jani,

I am already debugging this issue. Issue got reproduced when we are locally running the icl_dmc_ver1_07.bin on ICL HW.

We could not see this issue with previous FW version icl_dmc_ver1_01.bin file.

1. Stepping { A, *} - > this stepping is mainly for A stepping ICL HW.

2. Stepping {*, *} -> this is the default stepping.

 If we try to load Steeping {A, *}, it is loading fine.

But getting issue with default stepping.

Also we need to add Stepping info for ICL also in driver code to fetch the correct FW  for particular HW Stepping.

Working on the same. 

Regards

Jyoti
