STM32H7S78-DK/MH1736 cannot detect st-link

[Gaobo]

I downloaded the boot code generated by following the settings in Figure 3 (the frequency configuration to 600Mhz) into the flash of the 0x08000000 starting address, and then the stlink cannot detect after re-powering (as shown in Figure 1). But my device manager can detect the device (as shown in Figure 2).

Can someone help me with that? Thank you very much!

Hello @Gaobo and welcome to the community;

Could you please

• Try to upgrade Firmware using STM32CubeProgrammer and erase external memory.

I hope this help you!
