Hi @KKR231 ,

   Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

  Whether you can do the CMSIS DAP debug in the MIMXRT1170-EVKB previously?

  Do you update the CMSIS DAP version or not recently?

  I think your situation may related to the following 2 points:

1. You may download some abnormal app to the flash, that will cause the debugger connection issues, you can refer to my document:

https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/RT-board-recovery-for-debugger-connect-issues/ta...

2. If you update the CMSIS DAP version

You can power on the board with the external DC power supply, or you also can find anoter USB cable to connect the SDP USB interface to power on it.

As I know, new CMSIS DAP have the power on issues, need to use ansother USB or the DC power to power on the board.

Please try it on your side.

If you still have question about ti, please kindly let me know.

Best Regards,

Kerry

Hi @KKR231 ,

  Thanks for your updated information.

  Please follow me:

1.  Board power off, then SW1 : 1-off,2-off,3-off,4-on

2. Find another USB cable, connect to the J20

3. power on the board.

4. open the MCUbootutility tool:

https://github.com/JayHeng/NXP-MCUBootUtility/releases/tag/v6.2.0

the related user manual is:
https://github.com/JayHeng/NXP-MCUBootUtility

Use the mcubootutility to do the mass erase:

After the erase finished, then can switch the SW1 back to internal boot mode, SW1:1-OFF,2-OFF,3-ON, 4-OFF, then use the on board CMSIS DAP download the code in the mcuxpresso IDE again.

Please try it.

If you still have question about it, please kindly let me know.

Best Regards,
