Hey @antti.havulinna @Rongzhong Li @3dp @leukipp @Lilie Boizumault, has anyone had any luck doing the same for Bittle and recent Arduino? I encountered the same avrdude issue as was mentioned above by several persons.

Note that I'm on headless Ubuntu 20.04, RPi Zero 2 W. Reset pin was assigned to GPIO 26. Also note that arduino-cli doesn't recognize the NyBoard. Wondering what option should I use there?
I tried the following 2 w/o luck:
arduino-cli upload -p /dev/ttyS0 -b arduino:avr:pro:cpu=20MHzatmega328 OpenCat
arduino-cli upload -p /dev/ttyS0 -b arduino:avr:uno OpenCat
