Help! Nucleo-H745ZI with ST-Link, 'No target connect'

[diverger]

When generate the project for the CM4 core, it seems I forget to enabled the SWD debug. Now, in Keil's debug wizard, the SWDIO shows 'No target connected'. My nucleo board is just a brick now.

​

Any method to unlock it?

BTW: I can reboot with BOOT0 pull high, it can recognize the board, and then I can download code for CM7, but not CM4. For CM4, it shows "Internal parameter error"...................

Many many Thanksssssssssssssssssssssss

Did you ever sort this out? I am seeing it too.

No, I didn't find a solution to this problem, the board is dead for me now. Hope you can figure out. :face_with_tears_of_joy:
