Hi friends, I tried to program my device from Arduino IDE on external PC. I did downloaded board to the Arduino. But, I couldn't communicate with my device. I see only COM3 port and it does not include anything. What can I do ?
You should leave the port empty. For serial monitor from external PC you need the remote serial monitor. Please read the complete manual here http://www.udoo.org/docs-neo/Arduino_M4_Processor/Programming_Arduino_M4_from_External_PC.html
