AS7 is claiming the non-existence of my Atmel-ICE fairly frequently.
Previously a cure was to swap in a different A-ICE and swap it out again.
That didn't work this time.
AS7 found the new serial number and still claimed the A-ICE (not the ATmega2560) did not exist.
What is the incantation to make AS7 believe in A-ICEs again?
Do I need to reinstall Windows?
I do not know what other information would be useful.
I'm hoping the problem was encountered by someone else who solved it.
BTW 'tis a real pain doing this from Windows.
Every carriage return takes me to the upper left corner.
