Send hard reset over serial

[matthgyver]

Hi,

Is it possible to send hard reset over serial please ?
Soft reset with echo -ne "\x03\x04\r" > /dev/ttyACM0 work well but I can't find the same thing for hard reset.

Thank's

You can use machine.reset(). Just send "\rimport machine;machine.reset()\r". To interrupt a running code, you may have to send Ctrlc-C beforehand and maybe wait a little bit.

Thank's Robert. Your answer help me to understand why that I tried does'nt work.

I just tested that and it work well without an active serial connection:

echo -ne "\x03\r" > /dev/ttyACM0 && echo -ne "\rimport machine;machine.reset()\r" > /dev/ttyACM0

@matthgyver FWIW rather than doing this manually, use pyboard.py as a library for interacting with the device. See https://docs.micropython.org/en/latest/reference/pyboard.py.html#using-the-pyboard-library
