Hello Fakhrul

1. I tested with JTAG cable only 2 boards and with both of them have the same issue. Third board was burned in a different way - through remote update option (RS232 and not from JTAG).

2. I tried to burn 'damaged' boards with different validated jic files, also with simplified jic with empty project (just pins were defined) and even tried to download only sof file.

3. The screenshot of the message attached.

Thank you.
