I am attempting to flash the Mega8u2 chip on an Arduino Uno R2 so that computers will be able to identify it as a MIDI device. Here is the information I’m working with GitHub - ddiakopoulos/hiduino: Native USB-MIDI on the Arduino.
I am using an Arduino Uno R3 as the ISP. I’ve uploaded the ISP code (found in the example folder) to the chip and set it’s COM port correctly when identifying it in the Command Line window.
I’m getting this error back…
avrdude: stk500_getsync<>: not in sync: resp=0x00
This is the line I am entering…
avrdude -p at90usb82 -F -P COM22 -c avrisp -U flash:w:HIDUINO_MIDI.hex -U lfuse:w:0xFF:m -U hfuse:w:0xD9:m -U efuse:w:0xF4:m -U lock:w:0x0F:m
