Tristan,
This is what I get
Perhaps the fuse values are incorrect!
MacBook-Pro-van-Jan-10:avrdude jankromhout$ avrdude -p m32u4 -c avrispv2 -P
/dev/tty.usbmodem00230362 -U efuse:w:0xFF:m -U hfuse:w:0xD9:m -U lfuse:w:0xFF:m
-U flash:w:leonardo.hex:i -U eeprom:w:leonardo.eep.hex:i
avrdude: AVR device initialized and ready to accept instructions

avrdude: Device signature = 0x1e9587 (probably m32u4)
avrdude: NOTE: "flash" memory has been specified, an erase cycle will be

avrdude: erasing chip
avrdude: reading input file "0xFF"
avrdude: writing efuse (1 bytes):

avrdude: verifying efuse memory against 0xFF:

Would you like this fuse to be changed back? [y/n]

Hi,
Flashing the Arduino Uno is giving no problems.
Try to flash the Leonardo.
I’m using the Pololu AVR programmer v2.1
This is my command.

It isn’t working
Can someone help me with this problem.
