openocd.txt
```brew install openocd```
make a file called openocd.cfg in a folder containing...
# Atmel-ICE JTAG/SWD in-circuit debugger.
interface cmsis-dap
# Chip info
set CHIPNAME at91samd21g18
source [find target/at91samdXX.cfg]
copy your bootloader to the same folder and call it bootloader.bin
```openocd -f openocd.cfg -c "at91samd bootloader 0; program bootloader.bin; at91samd bootloader 1024; exit reset"```
NOTE: fix the bootloader size in bytes (1024...)

Finally got around to trying this!
I needed to add an init to get it to flash, but it works great, thanks!

openocd -f openocd.cfg -c "init; at91samd bootloader 0; program bootloader.bin; at91samd bootloader 1024; exit reset"
