    Hi,


    Apologies for the delay in response as I was checking this with our internal team.


    The conclusion after discussed with engineering is when the tamper resistance bit is set, that means the device will accept only encrypted POF. Therefore, you can’t reprogram the key.


    Since they key is lost and unable to reprogram the key, the device is unable to program.


    Regards,

    Aiman

I just realized that I my primary post, I made a mistake. I talked about non-volatile key, which is not correct. I configured FPGA for a volatile key.

My issue still remains but I just wanted to correct my mistake and it seems I can't edit my post.
