ST-FLASH(1) STLINK ST-FLASH(1)

NAME

st-flash - Flash binary files to STM32 device

SYNOPSIS

st-flash [OPTIONS] {read|write|erase} [FILE] <ADDR> <SIZE>

DESCRIPTION

Flash binary files to arbitrary sections of memory, or read arbitrary addresses of memory out to a binary file.

You can use this instead of st-util(1) if you prefer, but remember to use the .bin image, rather than the .elf file.

Use hexadecimal format for the ADDR and SIZE.

COMMANDS

write FILE ADDR
Write firmware FILE to device starting from ADDR
read FILE ADDR SIZE
Read firmware from device starting from ADDR up to SIZE bytes to FILE
erase
Perform a mass erasing of the device firmware

OPTIONS

--version
Print version information
--debug
TODO
--reset
TODO
--serial iSerial
TODO
--flash=size
Override the device's normal flash size, where size is the flash size in bytes. It can be specified in decimal, octal or hexadecimal. The size argument can optionally be followed by 'k' for KB or 'm' for MB. Examples --flash=128k or --flash=0x080k.

EXAMPLES

Flash firmware.bin to device 

$ st-flash write firmware.bin 0x8000000

Read firmware from device (4096 bytes)


$ st-flash read firmware.bin 0x8000000 4096

Erase firmware from device


$ st-flash erase
