I try to connect STM32H750-DK with STM32CudeProgrammer but it shows as the picture. What should I do?

Hello wsuwa.1 (Community Member)
I don't reproduce this problem on my side with the latest version v2.13.0 and the same DK board.
Please follow the very good recommendations of Tesla DeLorean to erase the firmware by connecting BOOT0 IO to 3.3V (shorting solder bridge R144 on pcb).
Best regards,

On all STM32 the BOOT0 pin is a GPIO which has the function to select different boot memory areas.
Depending of voltage level apply, you can force the MCU to boot in user flash (Default when BOOT0=GND) or in Bootloader mode in system memory (BOOT0=3.3V).
As explained, if your able to set BOOT0 (by closing unmounted R144 on pcb) you will have chance to connect and erase the flash of the board.
I suggest you to read the document below in chapter 2.6 Boot configuration.

Not sure anyone here is that invested, perhaps you work with someone who can assist you?
You could bridge the R144 pads with a wire, or wire some jumper or switch.
You should probably establish that the code you put on the board is where the problem is. As I understand the H750B-DK it uses the LDO, where as the H745I-DISCO uses the SMPS.

That might work, but these H7's can be bricked quite easily to the point where serious intervention is required. Why there's not a jumper or switch perplexes me.

I can't find where the BOOT0 pin is exactly on my STM32H750B-DK board
