I tried the Loop-back test and it works. I am using windows 10 and the sparkfun redboard. I have already checked the COM ports and made sure that they are correct. I have also made sure that I have the correct board selected. I am using the Arduino IDE. I have nothing connected to my Arduino and
my program is super simple and bare. It used to work perfectly fine, but now it does not work to upload to it. The "13" light is not turning on at any point, although it used to before the problems occured. I enabled verbose for upload and here are my error messages:
