Messing with an Arduino Zero sans-IDE, on a ThinkPad running Arch Linux.

Atmel AVR uses avrdude but Atmel SAM (ARM core) uses BOSSA.
BOSSA mainline (including Arch's bossa-bin AUR package) currently doesn't support Arduino Zero;
$ bossac --port=ttyACM0 --info
No device found on ttyACM0
Arduino uses a bossac binary built from the arduino branch at https://github.com/shumatech/BOSSA/tree/arduino (it took me a long time, and recompiling the cdc_acm kernel module with debug enabled, to figure that out).
$ bossac --port=ttyACM0 --info

cd ~/code/bossa
make
mkdir -p ~/bin && ln -s ~/code/BOSSA/bin/bossa* ~/bin/
- ARM's CMSIS - Cortex Microcontroller Software Interface Standard is a thing.
- Atmel's Atmel Software Framework (ASF) supports CMSIS.
