Prepare or Fix Linux for EmuFlight, BetaFlight, CleanFlight, ButterFlight, or any other *Flight

Linux Serial/USB device access

Edit/create udev rules: (use vi, nano, or any text editor)

sudo nano /etc/udev/rules.d/50-myusb.rules

Copy/paste this content and save it: (See STM list here: https://devicehunt.com/view/type/usb/vendor/0483)

# ALL STMicroelectronics devices & DFU
SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="****", GROUP="plugdev", MODE="0664"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="****", GROUP="plugdev", MODE="0664"

Then reload the rules:

sudo udevadm control --reload

You must add yourself (username) to plugdev group.

sudo usermod -a -G plugdev $USER

You must add yourself to the dialout group for tty/serial permissions: (This fixes Failed to open serial port: FILE_ERROR_ACCESS_DENIED)

sudo usermod -a -G dialout $USER

You must now logout/login to update user access rights. Afterward, you may run Configurator which should properly connect to flight controllers.


note: some older OS could use GROUP="users", but newer OS seem to not allow it.

Failed to open serial port: FILE_ERROR_ACCESS_DENIED

See also: https://steronius.blogspot.com/2020/08/linux-emuflight-betaflight.html

Problem/Symptoms:
Failed to open serial port: FILE_ERROR_ACCESS_DENIED
betaflight linux failed to open serial port
butterflight linux failed to open serial port
cleanflight linux failed to open serial port
butterflight can’t flash firmware
betaflight can’t flash firmware
cleanflight can’t flash firmware

Cause:
Linux user accounts require permissions for Serial and USB subsystems.

Solutions:
1) For Failed to open serial port: FILE_ERROR_ACCESS_DENIED :
ref: https://websistent.com/fix-serial-port-permission-denied-errors-linux/

sudo usermod -a -G dialout $(whoami)
newgrp dialout   #(temp workaround to bypass logout & re-login requirement)

2) For unable to flash firmware to flight controller (FC) :
ref: https://github.com/ButterFlight/butterflight/blob/master/docs/USB%20Flashing.md

echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE="0664", GROUP="plugdev"' | sudo tee /etc/udev/rules.d/45-stdfu-permissions.rules
sudo usermod -a -G plugdev $(whoami)
newgrp plugdev   #(temp workaround to bypass logout & re-login requirement)

As always, good luck!
