I would like ask you how is in milk-v initiated the program compiled in arduino ide?

If you want to shut down the running Arduino firmware, execute:

echo stop  > /sys/class/remoteproc/remoteproc0/state

If you want to disable the Arduino firmware that automatically runs on startup, execute:

rm /lib/firmware/arduino.elf
sync
reboot

I add:

The arduino process is possible to start again.

[root@milkv-duo]/sys/devices/platform/c906l_rproc@0/remoteproc/remoteproc0# echo stop > state

[root@milkv-duo]/sys/devices/platform/c906l_rproc@0/remoteproc/remoteproc0# cat state

offline

[root@milkv-duo]/sys/devices/platform/c906l_rproc@0/remoteproc/remoteproc0# echo start > state

[root@milkv-duo]/sys/devices/platform/c906l_rproc@0/remoteproc/remoteproc0# cat state

running

[root@milkv-duo]/sys/devices/platform/c906l_rproc@0/remoteproc/remoteproc0#

Many thanks to Spotpear for your answers!

One more add:

It is possible to stop arduino process, then create new arduino.elf (by renaming or copying...)

and then to start the other arduino process.

That is very simple way to changing the arduino code.

See you
