I have a problem with my Arduino Mega 2560. Uploading of any code doesn't work. I tried the easiest one "Blink" and also a lot of other examples. When I try to upload the code first the L light blink twice. Then the TX RX lights blink once or twice and then the L light is on constantly.
I tried all the stuff from the list in the troubleshooting guide (only the cable I wasn't able to change because I don't have another one at the moment)
By the way: I bought the board a half year ago and it worked well. I toke it with me on a flight to the USA one month ago. So it was in my baggage. After that I tried to use it yesterday and it didn't work.It didn't look like it has any demage.
So I think maybe the cold temperatuer in the airplain's baggage area could have destroyed anything. --> Any Idea what could have been happened?
Or did anyone else have had the same problem and can may help me? Even if you can post me an old forum entry you would help me a lot.
Thank you very much.
