HIDKey

BootloadHID is a USB boot loader for AVR microcontrollers.-his is the README file for bootloadHID.



BootloadHID is a USB boot loader for AVR microcontrollers. It can be used on

all AVRs with at least 2 kB of boot loader section, e.g. the popular ATMega8.

The firmware is flashed into the upper 2 kB of the flash memory and takes

control immediately after reset. If a certain hardware condition is met

(this condition can be configured, e.g. a jumper), the boot loader waits for

data on the USB interface and loads it into the remaining part of the flash

memory. If the condition is not met, control is passed to the loaded firmware.



This boot loader is similar to Thomas Fischl s avrusbboot, except that it

is built on top of the HID device class. This implementation is more user

friendly on Windows, since no kernel level drivers need to be installed.
