st-flash [--verify] command [file] [address] [size]

st-flash is a command-line tool for reading, writing, and erasing the flash memory of STM32 microcontrollers through an ST-Link programmer/debugger. It is part of the open-source stlink toolset.
The tool works with raw binary files and requires explicit memory addresses for read and write operations. The flash base address for most STM32 devices is 0x8000000. Write verification can be enabled with --verify to confirm the programmed data matches the input file. The erase command clears the entire flash memory, and reset restarts the microcontroller after programming.
