## プロジェクトの歴史と使われ方

BootloadHID is Objective Development's HID-class USB bootloader for AVR microcontrollers using the V-USB software USB stack. Its history is narrow but useful: it solved the practical problem of updating small AVR firmware over USB without requiring custom kernel drivers on Windows.

### プロジェクトの歴史

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.

### 採用の歴史

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.

### 使われ方

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.

### パッケージ好きにとっての重要性

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.

### タイムライン

- 2007: First listed BootloadHID archive published by Objective Development.
- 2008: Releases add USBaspLoader improvements and code-size work.
- 2010: Release adds gcc 4 optimizations and a command-line utility option.
- 2012: Latest listed release updates the driver and fixes newer gcc/avr-libc builds.

### Related projects

- Related projects include Objective Development's V-USB firmware-only USB stack, Thomas Fischl's avrusbboot, USBaspLoader, and third-party HID boot flash tools for Windows.
