Projektgeschichte

The official page presents BootloadHID as a USB boot loader for AVRs with at least a 2 kB bootloader section, including popular chips such as the ATmega8. The bootloader occupies the upper flash area, starts after reset, and either waits for USB upload when a configured hardware condition is met or jumps to the target firmware.

Objective Development's release table shows public BootloadHID archives from June 2007 through December 2012. Release notes mention code-size optimizations, fixes for larger flash devices, improvements ported from USBaspLoader, updates to the V-USB driver, and compatibility fixes for newer gcc/avr-libc.

Adoptionsgeschichte

BootloadHID's adoption was mainly in the AVR hobbyist and small-device firmware world, where V-USB made USB possible on microcontrollers without dedicated USB hardware. The project was attractive on Windows because HID devices could use built-in OS support rather than a custom kernel driver.

Wie es verwendet wird

Users configure the boot condition and firmware settings in the source tree, flash the bootloader into the AVR boot section, reset the board into bootloader mode, and upload an Intel HEX file with the `bootloadHID` command-line tool. The host-side tool accepts the firmware image as its main argument.

Warum Paket-Nerds sich dafür interessieren

BootloadHID is package-nerd significant as a tiny embedded tool that package managers keep alive after upstream release activity slowed. It represents the era of software-only USB on AVR parts and the practical value of HID-class protocols for avoiding driver installation.
