I’ve just saw you post @Petrakis .
Unfortunately I don’t have any idea how to do this. I’m stuck in trying to install the CH340 driver. I downloaded the linux .zip that comes with a Makefile and the ch34x.c file, but I can’t install it.
make[1]: Entering directory '/usr/lib/modules/4.20.3-1-MANJARO/build'
make[1]: *** No targets specified and no makefile found. Stop.
make[1]: Leaving directory '/usr/lib/modules/4.20.3-1-MANJARO/build'
make: *** [Makefile:5: default] Error 2
An even after that, I don’t have any idea on how to flash the arduino board…
