Hi there,

I have a Nano which is not responding when I try and upload to it - although the board is still visible.

It seems to be stuck in an infinite loop. I uploaded a sketch to to read 3 potentiometers and send values back over serial, and I also set the LED on 13 to blink in the loop (the loop had a delay of 50 ms).

Now, the board is unresponsive, but the LED on 13 blinks constantly, and resumes the instant I release the reset button.  I have removed everything from the board...

Reading some other threads, I think this might be due to heavy use of Serial, or is this something else (sounds ridiculous)

The loopback test works, even when not in reset.

Any ideas what I can do?

Unfortunately, I don't have another arduino to try ISP...

Any help would be appreciated.




It could be in a watchdog loop.

If you burn the bootloader with the Arduino, the fuses are also set. Or did you do that already?
