It is possible to burn Arduino remotely?

if you look at this post

you can copy it over to lib/firmware

and run, where zephyr .elf is your arduino compiled elf

echo stop > /sys/class/remoteproc/remoteproc0/state
echo -n zephyr.elf > /sys/class/remoteproc/remoteproc0/firmware
echo start > /sys/class/remoteproc/remoteproc0/state
