Hi AlexHalf,


My apologies, I missed your post. I'm trying to understand the situation here, appreciate if you could answer these:

  1. does this issue only happen on these two boards? I understand you have tried on the 3rd board and working fine, correct?
  2. Have you tried with a new jic generated from a new simple design?
  3. Could you provide the error screenshot?


Regards,

Fakhrul

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.

Alex
