Hi li57752009，
Sorry for my later reply.
Please follow me to try to erase the external flash at first.
Your U3 module is controlled by the EN pin which is the PMIC_ON_REQ, it is the RT1052 PMIC_ON_REQ pin.
So, now, you need to erase the external flash at first, then you should can debug your board again.
I suggest you download the SDK led_blinky project after the external flash is erased.
1. Download the MCUBootUtility tool from this link:
https://github.com/JayHeng/NXP-MCUBootUtility/archive/v2.4.0.zip
the related user manual is:
https://github.com/JayHeng/NXP-MCUBootUtility
2. Let your MIMXRT1050-EVKB board enter the serial download mode.
SW7 1-OFF, 2-OFF, 3-OFF, 4-ON
Power off and power on the board again
3. User the MCUBOOTUtility tool to connect your board
and erase it.
After you erase it, then you can reset the chip, and use your IDE download the code again.
Please try it on your side.
If you still have questions about it, please kindly let me know.
Best Regards,
Kerry
