Updating the APM2.x BootLoaderΒΆ

The Atmel 2560 boot loader should not have to replaced, however sometimes developers or users or a brownout etc., will corrupt the boot loader or the fuse bits. This renders the Mission Planner and other firmware uploads unsuccessful.

You will need an AVI ISP Programmer to flash the boot loader and set the fuses correctly.

The 2560 Boot loader HEX file is located in the APM source downloads for Arudcopter, Plane, Rover in the folder.

Editors: I can’t find details for flashing boot loader - need to add a link or details. Also is there a stand alone download location for the boot loader?
