[SOLVED] Arduino side hangs, how to reboot via software

Hi guys

Every day or two, the sketch running on my yun just stops working.
The console stops responding and I have to phisically unplug the power and plug it back to make it work again.
Until I'll debug why this happens, is there a way to reboot the arduino part from linino?
In fact, issuing a "reboot" does not bring the arduino sketch up...

Thanks

to anyone interested, to restart the MCU you can just execute /usr/bin/reset-mcu
to restart the bridge library /usr/bin/kill-bridge then /usr/bin/run-bridge

I have the same problem…
With this have you solved?
