Arduino Nano Programmer Issue

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

Yes, I have tried those suggestions, but to no avail

In the tools menu what board and bootloader do you have selected?

Make sure there are no Serial ports open or trying to access the Serial port the Arduino Nano is on. (You probably have done this too). If you could provide more detail on what you are trying to do I might be able to help you more on your situation.
