I am trying to use platformio to program an stm32 device with libopencm3 on a laptop running ubuntu. The code compiles but when I try to run it it doesn't work an instead says it "Failed to init device" and "*** [upload] Error 1".
It isn't that it can't see the device because if I try to upload it without anything plugged in it gives a different error. I suspect it might be because my 99-platformio-udev.rules. I tried to follow the instructions on the platformio site. To that end I do have a file named 99-platformio-udev.rules at /etc/udev/rules.d/99-platformio-udev.rules that does match the most updated one on the website and did do sudo service udev restart, however I think I might be doing the next step wrong. It says
Ubuntu/Debian users may need to add own “username” to the “dialout” group if they are not “root”, doing this issuing
sudo usermod -a -G dialout $USERsudo usermod -a -G plugdev $USER
but I'm not sure what it means by that, so I tried to run the commands as is but I'm assuming that is wrong. What should I do? Below I will put the devices connection to the laptop, how I inputed the command, and the full output/error. If there is any other information needed please ask
