How to set up betaflight fc with Ubuntu

Betaflight for ubuntu

1. Create a rule for the DFU

$ (echo '# DFU (Internal bootloader for STM32 MCUs)' echo 'ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE="0664", GROUP="plugdev"') | sudo tee /etc/udev/rules.d/45-stdfu-permissions.rules > /dev/null
 
 2. Monitor connection and find your model (unplug/plug the fc while this cmd is active)
 
$ udevadm monitor --environment --udev | grep ID_MODEL_ID
 
 3. Update the /etc/udev/rules.d/45-stdfu-permissions.rules file with your model. E.g, my MODEL_ID is 5740, and the .rules file
 ends up like this:
 
 # DFU (Internal bootloader for STM32 MCUs)
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE="0664", GROUP="plugdev"

# ix5 
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="5740", MODE="0664", GROUP="plugdev"
 
4. Now reload rules

$ sudo udevadm control --reload-rules && udevadm trigger

5. You can then test the rule using when your FC is plugged in:

$ udevadm test $(udevadm info -q path -n /dev/ttyACM0)

Ensure line "MODE 0664 /etc/udev/rules.d/45-stdfu-permissions.rules" is present

6. Now check the group at which the device belongs to

You can then test the rule using when your FC is plugged in:

$ ls -lah /dev/ttyACM0 
crw-rw---- 1 root dialout 166, 0 mars  17 21:57 /dev/ttyACM0

Here it is in dialout, obviosuly thinking it is a modem. 

7. Stop the modem service

$ sudo systemctl stop ModemManager.service

8. Add yourself to the group plugdev and dialout (don't know which one is the "correct one")

$ sudo usermod -G plugdev -a <username>
$ sudo usermod -G dialout -a <username>

9. I had to reboot for this to work. 

Beautiful, THANKS!

As usual, each flavor and version of Ubuntu behaves differently (I'm still on 18.04). I messed around with this for a while, never seeing the MODE 0664 thing from the test... (for number 5 test):

MODE 0664 /etc/udev/rules.d/45-stdfu-permissions.rules

So I tried the hint from jobot1984 commented on Jan 21, 2018 and then unplugged/plugged in, rebooted BetaFlight, and my drone was recognized: ProTek25 (with XM+ receiver).

Thanks everyone!

Just sending a big TANK YOU for this guide. Worked perfectly for me (I even had the same vendor and model ids :) )

Just a side note that might be helpful to some.

In Arch based distributions like Manjaro there is no "plugdev" group. When creating the udev rule the permissions need to be given to those in the uucp group, the file should contain thiese two modified lines instead:

# DFU (Internal bootloader for STM32 MCUs)
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="df11", MODE="0664", GROUP="uucp"

As you can see the only thing that changed was plugdev to uucp.

You will also need to add your user to the uucp group, that can be done with the following command:
sudo usermod -aG uucp

Hope this helps someone out.

Works for me in Ubuntu 20.04. Then of connect my TinyGo, I set the necessary permissions using command (sudo chmod +666 /dev/ttyACM0), I made a consult (lsusb) to corroborate necessary idVendor and idProduct. It works for me when I don't use mi idProduct, ie ID_MODEL_ID=5740, instead I use the default ATTRS{idProduct}=="df11", set the mode to MODE="0666", and reload the rules. After add my user to both groups plugdev and dialout, finally I can install successful my new firmware Betaflight / STM32F411 (S411) 4.3.0 Jun 14 2022.

Ubuntu 22.04.2 LTS

Firstly, for Betaflight Configurator to actually work with flight controllers, current user was added to "dialout" group:

sudo usermod -aG dialout $USER ($USER - system variable that contains the current user login);

Then, created low-priority rule for STM32 devices:

(echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", ACTION=="add", MODE="0664", GROUP="dialout"') | sudo tee /etc/udev/rules.d/80-local.rules

Then - reloaded udev rules:

sudo udevadm control --reload

That solved the problem for me.
Much appreciated the authors effort; used

Dear NightCrack thank you very much!
