Hi @AsafTv

Please accept my apologies for delaying on my response. I really appreciate your patience.

Regarding your issue, it seems that it is not a problem with the code, because that error always appear when your target is not being recognized by your computer or some hardware issue is happening.

Also I would like to know if you still need help with the code for emulating EEPROM, because I did not receive answer from you to the email that I sent you. I achieved to get a demo that might be helpful for the request that you asked on your other closed request.

Please let me know your comments, and I will stay tuned to your answer.

Best Regards.
Pablo Avalos.

Thanks a lot for letting me know and your time waiting for.

I will share it with you through an email sent by tech support portal. Please stay tuned to your email to see the folder. The example is called flexmem_demo in src -> projects.

Thanks a lot.
