2boots: Arduino/AVR serial and SD card bootloader

Tuesday, April 3rd, 2012

Martin tipped us off to an AVR/Arduino  serial and mmc/SD card bootlaoder. It was designed to fit the same 2kb memory area that the usual Arduino booloader fits into, but can load firmware from an SD card too. Very useful for on "in the field" programing. This is a proof-of-concept...
