That left Caterina-Leonardo.hex or Leonardo-prod-firmware-.hex. It seemed logical to not use Leonardo-prod-firmware-.hex, since that was likely an old and obsolete bootloader based on the date. hex files, only three of which contained "Leonardo" in the name: Caterina-Leonardo.hex I'd read that the Leonardo uses the "caterina" bootloader, and the directory /usr/share/arduino/hardware/arduino/avr/bootloaders/caterina contained several. Again, I just made an educated guess based on naming. On a side note, I'm not 100% sure if Leonardo-prod-firmware-.hex was the correct bootloader to use. So I suspect there's a bug in the Arduino IDE that burns an incorrect or corrupted bootloader.Īfter running this, ard-reset-arduino works correctly, and make upload can successfully upload a sketch again. Oddly, this ran in seconds, whereas the Arduino IDE took almost 5 minutes to burn the bootloader.

I'm not sure if the first and last command to write the lock bytes were necessary, since they returned the verification error content mismatch error, but they didn't seem to break anything either. Using some examples and similar questions, such as this one and this one, I fixed udev rules for the AVRISP MkII programmer, then I manually reflashed the Leonardo's bootloader with with the MkII by running: avrdude -c avrispmkii -p m32u4 -P usb -B 8 -u -e -U lock:w:0x3F:m -vĪvrdude -c avrispmkii -p m32u4 -P usb -u -U efuse:w:0xcb:m -vĪvrdude -c avrispmkii -p m32u4 -P usb -u -U hfuse:w:0xd8:m -vĪvrdude -c avrispmkii -p m32u4 -P usb -u -U lfuse:w:0xFF:m -vĪvrdude -c avrispmkii -p m32u4 -P usb -U flash:w:/usr/share/arduino/hardware/arduino/avr/bootloaders/caterina/Leonardo-prod-firmware-.hex -vĪvrdude -c avrispmkii -p m32u4 -P usb -U lock:w:0x0F:m -v Why am I unable to program the Leonardo via avrdude and USB? For development, where I might need to make dozens of revisions, this turnout is far too slow. I can program it still using the AVRISP MkII programmer.but obviously that's a huge inconvenience since it takes about 5 minutes just to upload the sample blink sketch, and even then it requires that I first power off the Leonardo, disconnect the programmer, and then power on. I have to manually unplug its USB cable to fix it. Or upload via the Arduino IDE, it makes the Leonardo disappear from USB, and blink rapidly.

It somehow uploaded a simple "blink" program, but now the it's completely unable to be programmed via USB. So I tried re-burning the bootloader via an AVRISP MkII programmer and the Arduino 1.8.2 IDE, but that only made things worse. I tried power cycling it, and unplugging the USB cable, but nothing worked. However, it became "stuck" and unresponsive, as Leonardo's sometimes do.

I was using Arduino-Makefile to upload code to a Leonardo via its standard make upload.
