Question

"Connection to MyST" Does Nothing

When I try to log into myST from the IDE, it literally does nothing. I click on the button, but no window pops up, nothing happens in the browser, nothing happens in the IDE, no new windows are created.

 

I don't even get any output on the CLI (if I start the IDE from the CLI).

 

What is going on here?

Hello @antonly 

Could you please check your connection via Window/Preferences/STM32Cube /Firmware Updater ..

Otherwise please check this article for more details.

Hi Souhaib,

 

after digging through the source code a bit, it appears that the embedded browser fails to start (probably due to running on NixOS and not being able to find some required libraries).

Since there was no way I could find to patch this embedded browser, I settled for running CubeMX inside a docker container with X pass-through, that worked okay.

If anyone's running into similar problems, here's my personal writeup.

 

Long story short, under Xserver, running STMCubeMX in podman like this seems to work, if your CubeMX is located in `/home/<user>/st/CubeMX/`:

 

```

podman run -it --rm -e DISPLAY -v ~/.Xauthority:/root/.Xauthority:Z -v ~/st:/st:Z -v ~/.stm32cubemx/:/root/.stm32cubemx:Z -v ~/STM32Cube/:/root/STM32Cube/ --net=host ubuntu
$ apt update && apt install -y xorg && ~/st/STM32CubeMX/STM32CubeMX

```

This eventually opens a CubeMX window that doesn't suffer from browser issues.
