Bridge between MCU and Linux module doesn’t work.
Some possibilities:
1/ You have used the
Serial class
in MCU sketch, like Serial.begin(9600), The bridge library in
Mega328P use the same Serial interface. So if you have the Serial code in the sketch. They will
conflict and bridge doesn’t work.
2/ The IDE get mess in the serial setting when you compile other sketch . In this case, you can
close the IDE and open it again.

Arduino IDE doesn’t detect LG01
Check below points if this issue happens:
The Arduino IDE version is 1.5.4 or later
Your PC and Yun LG01 are in the same network.
Try to access the LG01 via Web or SSH, then check the IDE again.
If above still doesn’t work, SSH log in the LG01 and run:
/etc/init.d/avahi-daemon restart
to
restart the service so IDE can detect the LG01.
