After successfully uploading code to my T-QT board multiple times in the past few weeks, it suddenly stopped receiving uploads with a "No serial data received" error. I uploaded the same code with the same cable to an identical board and it works fine. Did I overwork or break the board? Can I recover from this? Here are the details.

I fixed it by doing the following: Press and hold the BOOT button on the board (located on the left side of the front of the screen), keep it tight, then plug in the USB and click to upload the sketch.
