Failed to start GDB Server - Error in intializing ST-Link Device

[Len_Heske]

Hi,

I'm a beginner programming a NUCLEO-N657X0-Q.

The LD5 is blinking and I can't get a connection to the board. Even with the demonstration code/project, it wouldn't work. In STM32CubeIDE I get the attached error message. As of yet, I never got to launch any program at all.

Thank you for your help!

What are the status LEDs doing?

Can you connect with the standalone STM32CubeProgrammer? If not, post a full screenshot of the error message when it fails.

Hello TDK,

see the attached video.

Thank you for your help :)

Hello TDK,

see the attached screenshot.

Hmm, sorry, I don't really know what the issue could be. It can see the st-link, the board has voltage. Should be working.

Hello TDK,

thank you very much for your attempt at helping me!

What would be your guess: is it a problem with my workstation and the software/driver setup, or a problem with the ST-Link module of my microcontroller?

For more context, I use both STM32CubeIDE for VS Code and the standalone application. I also use STM32CubeMX and STM32CubeProgrammer, although I'm very unfamiliar with the latter and don't really know what to do with it.

I think I set up the work environments and projects correctly. I previously coded on a NUCLEO-C031C6 and got everything to work before. Granted, that MCU is way simpler and doesn't have an FSBL and secure applications.

The N657X0 chip also doesn't use flash which makes it even more fragile in the hands of a beginner like me :)

I usually code on a register level and don't use HAL or LL, so I somewhat understand how things work but then again not really :D I'm still very much a beginner, especially when it comes to anything outside of the register logic.

Greetings

Case closed,

all I had to do is rearrange the pin bridges of BOOT0 and BOOT1. The getting started manual said to set both high as the default position.

Turns out, I had to set both low. Now I can run my code without any issues :)

Cheers and thank you
