I cannot seem to upload sketches to my Duemilanov.
On Ubuntu, the arduino terminal displays: avrdud: stk500_recv(): programmer is not responding On Windows: avrdude: avrdude: stk500_getsync(): not in sync: resp=0x00
Tried reburning the bootloader:
avrdude: error: could not find USB device "USBasp" with vid=0x16c0 pid=0x5dc
.
When I attempt to upload a new sketch, the Arduino RX/TX lights do not do anything. The "L" LED blinks once and that is all. While the IDE is "uploading" the new sketch, the Arduino begins running the previously loaded sketch as if completely ignoring the new data.
Sometimes the IDE will get stuck "uploading" and the TX light on the board will blink indefinitely.
When I first plug the board in to my PC, the "L" LED blinks 7 times after TX/RX blink a few times.
The most strange thing I have figured out is that if I completely unplug all of the data lines that are connected to the board it works fine. I am able to upload without a problem so long as nothing is plugged into the board (not even a 5V, GND, or digital pin).
I tried this and it works fine: http://forum.arduino.cc/index.php?topic=73748.0
Any suggestions? I was literally just using it without a problem 24 hours ago.
