Hi @dreamdf

It seems that your MCU is temporally bricked.

To recover the debug access, please try to set the MCU into ISP mode, this way bootROM will execute, setting the MCU into a known state. Once it is set into this state, please try to do a mass erase and program your application one more time.

Please let me know your results.

Hi @dreamdf

I am sorry for the delayed respose, I missed your reply.

I understand that you can program over ISP, but did you used USB connection or UART?

Did you manage to find out something else during this time? If yes please let me know.

Other thing we could check is : jumper setup on your FRDM board, could you share a picture where we can see the jumpers?
