Arduino YUN , how to tell when linux is booted and ready ?


is there a way to know when linux is booted (white led is on) with an arduino function ?


maybe a Bridge.begin() is enough:

Starts Bridge, facilitating communication between the AVR and Linux processor. This should be called once in setup()
begin() is a blocking function. Once you call Bridge.begin(), nothing else will happen in your sketch until it has completed.

Or you can try to execute a Linux process using Process.

You want to know it on the sketch side or on the linux side?

I use a browser and attempt to log into the Yun Web control panel. Or I use Putty and try to log into OpenWrt.
