I have a sketch for an Arduino Nano. I'm compiling it on my build server and get these 3 files:
Now I need to be able to upload/flash them onto the board (connected via a serial interface) without
arduino-cli. Mainly because I can't install it via
apt-get which means I'd have to start jumping through loops to be able to use it (stuff like keeping it up to date, installing, etc. on hundreds of devices).
So I was wondering if there are any tools in the debian repositories I can use to upload the compiled sketch and if so how.
I've been looking for a solution and came across several answers and topic but strangely enough all either use
arduino-cli, other specialized tools or link to dead pages or pages that no longer contain the answer.
