## Project history and usage
stm32flash is an open source cross-platform flashing utility for STM32 ARM microcontrollers using the built-in ST serial bootloader over UART or I2C. Its history is small but useful: it is the serial-bootloader counterpart to USB ST-LINK tools.
### Project history
The official SourceForge wiki says stm32flash was originally written by Geoffrey McRae and has been maintained by Tormod Volden since 2012. The same page identifies the SourceForge Git repository as the code host and also notes a GitLab mirror.
### Adoption history
The SourceForge wiki documents release downloads and version 0.7 released on 2022-03-26. The input package metadata lists availability in Homebrew, Debian, MacPorts, Nix, Ubuntu, Alpine, and openSUSE-related package managers, showing that it remains packaged for embedded workflows.
### How it is used
Users run stm32flash against a tty or I2C device to identify devices, read or write flash or RAM, verify writes, erase pages, start execution at an address, reset on exit, and optionally use GPIO sequences to enter bootloader mode.
### Why package nerds care
Package nerds care because stm32flash is a minimal C-style command-line utility for boards that expose the ROM bootloader through common serial adapters. It packages the kind of hardware recovery and firmware-flashing workflow that developers want available from a distro or Homebrew install.
### Timeline
- 2012: Tormod Volden became maintainer according to the official SourceForge wiki.
- 2022: stm32flash 0.7 was released on 2022-03-26 according to the official wiki.
- 2020s: The official wiki documents UART and I2C transports, SourceForge Git hosting, and a GitLab mirror.
