a new problem found in my path toward my configuration of the intel edison to work as the central brain of an intelligent traffic light network, I was trying to upload my new sketch that would allo to communication the arduinao expansion board with the Edison Yocto Linux and start to change the timing of the different traffic lights but I am faced with a strange error that doesn't allow me to upload the sketch file to the arduino.
