STM32H7S78-DK flashing issue: "Failed to execute MI command"

[Berlin-raj123]

Hello,

I am working with the STM32H7S78-DK board and I want to toggle the LEDs LD1 (PO1) and LD2 (PO5).
I followed the instructions from this GitHub resource:

https://github.com/ST-TOMAS-Workshop/stm32h7s_workshop/blob/main/1_external_memory/handson/1_extmem_intro.md 

and this YouTube video:

However, when I try to flash my program into the development board, I get this error:

I am not able to program the board because of this.

:right_arrow: Can anyone guide me on how to solve this flashing issue?
:right_arrow: Do I need to configure something specific in STM32CubeIDE or CubeProgrammer for STM32H7S78-DK?

Hello @Berlin-raj123 ;

Which STM32CubeIDE version are you using? Could you please with the latest toolchain version.

I recommend you referring STM32CubeIDE: How to debug an STM32H7Rx/Sx project without flashing boot every time. - STMicroelectronics Community  article and follow the steps indicated.

Are you experiencing the same issue with STM32CubeH7RS cube firmware Examples?

I hope this help you.

Thank you.
