I have an atmega 2560 board that worked for about a month, until all of a sudden it stopped connecting to the software it was working with (just hangs). It also no longer accepts sketches with this message:
avrdude: stk500v2_ReceiveMessage(): timeout
(same message repeated several times)
avrdude: stk500v2_getsync(): timeout communicating with programmer
I've scoured the forums and the net in general and found that this is a fairly frequent problem, and a solution that seems to work for everyone is burning the bootloader again. The problem is, I did burn the bootloader (using an UNO as an ISP), in fact several times now, and I still can't upload anything: same timeout error persists.
Unfortunately I'm very new at this and don't know how to troubleshoot the issue further. Are there any steps I can take to fix this, or at least conclude that the board isn't salvageable?
Thanks for reading.
