Open source flash program for the STM32 ARM processors using the ST serial bootloader over UART or I2C

stm32flash 0.4 was released 2014-10-04 and is available at https://releases.stm32flash.googlecode.com/git/stm32flash-0.4.tar.gz

The 0.4 version is the work of Antonio Borneo and includes support for programming over I2C. See the included I2C.txt for more information. The code has been refactored to make it easier to add other transports.

Features

• UART and I2C transports supported
• device identification
• write to flash/ram
• read from flash/ram
• auto-detect Intel HEX or raw binary input format with option to force binary
• flash from binary file
• save flash to binary file
• verify & retry up to N times on failed writes
• start execution at specified address
• software reset the device when finished if -R is specified
• resume already initialized connection (for when reset fails, UART only)
• GPIO signalling to enter bootloader mode (hardware dependent)

Usage

See the included manual page for up-to-date, complete usage instructions.
