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
