Remote Debugging with ST Link V3 Set

[stmAdmin]

Hello, I have an stm processor (stm32h7b3zitx) connected to an ST Link V3 that is on an ubuntu server. My goal is to connect to the ST Link and run a remote debugging session from my windows laptop running the stm32CubeIDE. To accomplish this I have been running st-util -v -p 61234 on the ubuntu server and using the following debugging configuration in the cube ide.

I am port forwarding via an ssh connection to expose port 61234 on my windows machine. When I go to debug, I get the following error

I've attached the verbose gdb log from host machine and the verbose st-util log from the ubuntu server to this post. I'm wondering what steps I can take to resolve this. Thanks in advanced to all who view this!

Hello @stmAdmin  

 Is it detected with STM32CubeProgrammer?  

Try connecting with STM32CubeProgrammer. Try mass erase, full chip erase, then try flashing.

Hi @Imen.D ,

The device is detected by stm32CubeProgrammer, here is the output from running STM32_Programmer_CLI -c port=SWD.

Im not ubuntu expert, but on windows i use com.st.stm32cube.ide.mcu.externaltools.stlink-gdb-server.win32_1.6.0.202101291314 for remote dubuging with used big complicated config.txt. Plus firewall open.

Thanks @MM..1 !! Using the linux equivalent (/opt/st/stm32cubeide_1.19.0/plugins/com.st.stm32cube.ide.mcu.externaltools.stlink-gdb-server.linux64_2.2.200.202505060755/tools/bin) I am able to connect and debug!! I had tried this before, but without using the info from config.txt, I needed to add the -d flag to connect in SWD mode so thank you for mentioning the config. @Imen.D I'd still like to know why this doesn't work with st-util since it's advertised as being capable of this functionality, but I'm going to mark this one as solved!
