Unable to Connect to NUCLEO-STM32H7S3L8 in STM32CubeProgrammer or STM32CubeIDE

Hello all, 

I am working with a NUCLEO-STM32H7S3L8 board, but I am unable to connect to it using STM32CubeProgrammer or flash firmware using STM32CubeIDE. However, I am still able to update the board’s firmware successfully.

Possible Cause:

I suspect that I might have pressed the reset button while flashing firmware to the device, which could have caused the issue.

Issue:

  • Unable to connect to the board via STM32CubeProgrammer
  • Unable to flash firmware in STM32CubeIDE
  • I cannot perform a hard reset because it requires a connection in STM32CubeProgrammer

Question:

What steps can I take to recover my board and regain access?

Any help or suggestions would be greatly appreciated.

Thank you!!
