Unable to get STM32CubeMonitor-UCPD working on Linux

[jd1234]

Hi.

Trying to connect a STM32G0 USB PD discovery kit using the linux
software package. Device is detected find, just opening the serial
port gives reasonable output (binary data which look like PD
messages). However the Java app doesn't work.

On linux machine 1, it crashes with a segmentation fault in libX11

On linux machine 2, the software fails to detect the discovery board. Not knowing anything about this software, it seems like it's trying to find the correct device, but it looks in the wrong place in /sys.

Hi @jd1234 

Could you specify which Linux version are you using ? Could you provide more details about your environment setup to escalate this issue?

[jd1234]

Sorry for late response.

The first machine is running Fedora 41, and I guess the problem spells
Wayland.

I did manage to get the app to detect the device on the second machine
(running good old X11) -- not sure if I did anything differently.

I'm happy with this right now. Thanks for your time.
