Mega board - Can't upload

Other Hardware 3rd Party Boards
1

Well I used to be able to, but not anymore (randomly). The IDE recognizes it as Mega, and even gives me a port wihch displays it (COM5), but it won't upload. I went to file >> preferences, and turned on "show verbose output during >> compilation and upload.

Here is what I saw when trying to upload (I had to trim some because it wouldn't all fit)

avrdude: error reading system wide configuration file "C:\Users\gmeyerho\AppData\Local\Arduino15\packages\arduino\tools\avrdude\6.3.0-arduino9/etc/avrdude.conf"

Any ideas what is going on?

Do you have all of your libraries in the same directory file?

Is your programmer correct under tools>programmer?

AVR board package is messed up.

Exit IDE, Delete C:\Users\gmeyerho\AppData\Local\Arduino15\ and restart the IDE. It should work now. If desired, you can update the board package through board manager - but I recommend avoiding that (and updating the whole IDE periodically instead).

Wow - yup that worked quickly! Thanks!
