Automatic upgrade doesn't seem to work. Although I did get a cryptic "Loaded plugin STK500," but I don't know why.
According to the manual, I can do a manual upgrade of the STK500 firmware by running AVR Prog in the Tools menu. Doing this causes a window to pop up that says
"No supported board found!"
"AVRprog version 1.40"
Does anyone out there know what I can do? Is this a problem with my serial port? I don't have any yellow exclamation points in Device Manager, but I'm still suspecting a driver issue, as the serial port uses nm9820cv but the driver says it's 9835.
Does anyone know anything about testing the serial port to see if it works?
