Hey all,
So I've recently migrated from Arduino 1.0.5 to 1.6.3 and I'm having some bootloader issues. I'm using some Microduino boards (Specifically the 1284p 8mhz variant) and I'm no longer able to burn the bootloader. I've gone through all the migration documentation I've found here and on Github, but now I'm stumped.
The effect is 0 error messages, but a very quick / atypically quick bootloader burn time, producing a board that doesn't respond.
Here's my verbose output on bootloader burn completion (Using an Arduino Uno): Output message of Microduino 1284p 8mhz & Arduino 1.6.3 · GitHub
And here's my boards.txt config:

Now when I attempt to program a freshly bootloader burned board, I get the following:

avrdude done. Thank you.
Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
I've checked / double checked my connections, and this board works fine on Arduino 1.0.5 (i've flashed the bootloader several times). As mentioned the "speed" is the most suspect element to me. It's very likely that there is still something I've missed in the migration to 1.6.3, and any help would be awesome! I'm just starting to dive into burning bootloaders, and this is the first time I ran into any issues.
