I've got an arduino uno and am having intermittent errors with errors uploading. Its always been working fine and the errors have only started today.
If I upload any of the example problems (blink, sensors etc) If I try and upload my project I get:
avrdude: verifying ... avrdude: verification error, first mismatch at byte 0x3beb 0x4f != 0x95 avrdude: verification error; content mismatch avrdude: Send: Q   avrdude: Recv: .  avrdude: Recv: . 
Could it be something in my project causing this?
Update: It seems to be size related. If my project gets around 15,500 bytes then I get this error :disappointed_relieved:
