I have sketches that used to work fine and now they don't. Even serial.print doesn't work so I can't troubleshoot it. Everything uploads properly and I get the "transfer complete" message, but serial monitoring shows nothing. I have tried the following: a different computer, reinstalled the firmware, powering down the galileo. I have also tried resetting the galileo and rebooting. Any help would be appreciated it.
Sometimes, I have seen that the Arduino IDE claims that the sketch was uploaded, but it never did upload the sketch.
To verify if this is happening, I upload the blink sketch. It is one sketch where you can see if it is running just by looking at the board. (there is a small LED that should blink). I would suggest trying that.
