Hello,
I was recently handed a "bricked" RT1050EVK board that we can no longer communicate with and I'm trying to fix it.
When the board is plugged in, the LEDs do not flash/toggle as I would expect with my RT1060EVK. Instead, the red LED (D20) is solid on when the board is plugged in. No other LEDs turn on, the board is not detected by the computer, and MCUXpresso doesn't recognize that it is even connected.
My suspicion is that the programming uP (LPC4322) needs to be reprogrammed. Are there instructions and a binary on how to do this?
Hello Chadgraham,
You can find instructions on how to reload the OpenSDA bootloader on your board in the link below.
I hope that this information helps!
Regards,
Gustavo
Hello Gustavo,
Still having issues de-bricking the board.
What should be my next steps?
Hello Chadgraham,
I think the i.MXRT EVKs were not affected by that known issue with Windows 10 due to the OpenSDA revision they were loaded with.
If reloading OpenSDA didn’t help then I would recommend trying ro reload the LPC4322 as you suggested by using the LPCScrypt tool (link below).

My apologies for all the trouble. I hope that this information helps!
