![]() and I hope this helps anyone else that runs into the problem.Why burn a CD or DVD on your Mac? Well, there are many reasons why you might want to do this. To my surprise this worked, and completed the re-burn of the boot loader.Īfter this point, every began to work as expected again and I was able to upload sketches via USB (AVR109) again.Ĭheers, thanks for reading. Regardless, this left the Arduino Micro halfway through the process of having the boot loader updated, from here I hopped into terminal, reconnected the dragon and manually ran the second avrdude command. Looking at the verbose log of the attempted burn via the Arduino IDE i could see that the first call was actually succeeding, but the second call was failing with avrdude unable to connect to the dragon on the usb port (perhaps because it was still busy, or yosemite needed time to close the connection, not sure). I didn't initially realize it but, it seems the burn of the boot loader via the Arduino IDE consists of two avrdude invocations, the first setting some fuse bits (i'd need to look up which) and the second uploading the boot loader, and i believe reverting a fuse bit. I was on the right track, the boot loader was definitely damaged on the arduino and needed to be re-burned. I seem to have managed to have solved my own problem, but since I spent a while trying to sort through this i figure i'll share for the next person that encounters this. Not sure why the "-Pusb" option works fine when I'm uploading sketches via ICSP but not to burn the boot loader. I'm thinking i toasted the boot loader somehow and need to re-burn it.

This is a new problem as things were working up until a day ago when I loaded a sketch that uses the serial port. That said, I can still upload sketches using the AVR Dragon and the ICSP interface. ![]() This led me to believe the bootloader was potentially hosed, however attempting to re-burn the bootloader with my AVR Dragon results in a different error. I can’t successfully upload a sketch from the Arduino IDE via the USB connection leveraging the AVR109 bootloader. I’ve been encountering some challenges dealing with my Arduino Micro, any help would be appreciated, I’ll do my best to provide all the detail I can.
