Question on STM32CubeIDE and remote debugging

Hello,

I am looking for some guidelines on how to make remote debugging possible with STM32CubeIDE running on Win10x64 and my STM32F070RB board connected to a Linux host.

Everything works fine when the device is connected locally, but there is an option to "connect to remote GDB server" in the IDE and I am not 100% on what should be running on the Linux host.

I installed stlink-server from ST on the linux host and run it with the following:

$ sudo stlink-server --network -p 61234 -d 3

Looks like the device is found:

IDE reports:

Failed to execute MI command:

Error message from debugger back end:

Remote replied unexpectedly to 'vMustReplyEmpty': timeout

Looks like there is some sort of a protocol mismatch, but I am not sure what is missing.

Thank you,

I think it's because you're trying to start stlink-server and you should start ST-LINK_gdbserver.

Markus,

Thank you for your reply. I was thinking this direction as well, however, it is not clear what stlink-server package use case is. But I am curious if st-link_gdbserver is available as a standalone package for linux? Perhaps I can check what is in the linux package for STM32CubeIDE and try to extract gdbserver from there, as I am currently not planning to install X on my headless linux box.

Thanks,

Eric

To my knowledge I don't think stlink-server is really meant to be called standalone, it gets called by CubeIDE. We don't distribute the gdb server standalone but we might in the future, it has been discussed. For now it's shipped with the installation of CubeIDE and located at:

For the love of all that is right, PLEASE release a gdbserver for Linux. I am completely stalled in working with the STM32G031 because I can't get the OpenOCD patches to work and I don't have (or want) Windows. I will never understand why chip vendors don't start with a multi-arch gdbserver and then layer the GUIs on later.

They do release a gdbserver for Linux, and they gave you the path. For the release current as of today (12/2022) it is at:
