6 # Released into the Public Domain
8 # This bootloader is based upon the MCHCK dfu-usb bootloader.
9 # DO NOT USE with Teensy based microcontrollers.
19 #| You _MUST_ set this to match the microcontroller you are trying to compile for
20 #| You _MUST_ clean the build directory if you change this value
