Topic: Problem uploading the code to my Arduino Uno R3 (Read 2345 times) previous topic - next topic


ever since I upgraded my arduino IDE to 1.6.7, I am not able to upload my code to the board. I am getting the error message as mentioned below. Is anyone else having the same issue or it's just me?
Any suggestions for troubleshooting would be greatly appreciated. Thanks.
