Fedora 41: STM32 BOOTLOADER Failed to open serial port

[vmorris]

Describe the bug

I am running Fedora 41 on x86.
I tried to flash firmware on my MATEKSYS BetaFlight FC F405-OSD STM32F405RGT6 today both v10.10.0 portable and the v11 webapp, both in Chrome and Chromium (not in snap or flatpak).

I've tried adding all the normal udev rules and more, plus have added my user to all the suspect groups.

Still, Betaflight Configurator always returns "Failed to open serial port" whenever I try to communicate with the device.

Is there some more fundamental way I can diagnose what's wrong here? Are there some additional debugging messages I can get out of Betaflight Configurator?

I tried a different flight controller and it seems to be working okay.
MTKS/MATEKF411RX(STM32F411)

Does this indicate my F405 is dead?

Thanks.

[haslinghuis]

Connect flight controller while holding boot button. DFU should show.
Can further debug with sudo dmesg or using dfu-util

[vmorris]

Thanks @haslinghuis
It actually just started working for me after switching the USB cable back from the mini whoop..

$ dmesg

We can close this.. I think I'm in good shape now.
