I am creating a simple control board with an arduino nano. In creating the software I uploaded my program many times to the board with no issues. However when I went to upload a change in my logic I cannot upload a program to the board. I get the following error:
avrdude: stk500_recv(): programmer is not responding
I have tried running through all the processor and programmer options in my IDE to no avail. Other things I have tried:
- Different computer (both MAC) -- could upload code one time and then back to the same issues
- Different arduino nano (nothing else connected to the board) -- same issue
- Different cables -- no better
- Reinstalled AVR boards library -- no help
- Reinstalled IDE -- no change
- Cleared cache and logs -- nothing
I have read some articles online and have tried just about everything that I can think of. Am I missing something? Any advice would be greatly appreciated
