Bridge: understand if and when Yun linux side is ready #2028
Description
This gist https://gist.github.com/wayoda/db3c023417757f726088 provides a proof of concept boot monitor on the Yun. Using the handshake line on pin 7, the sketch is able to tell when the linux side is ready. Consider using this technique as an alternative to the current "read the output and wait for a prompt" algorithm.
