NAME

st-flash - Flash binary files to STM32 device

SYNOPSIS

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

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.

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
reset: Reset the target

--version: Print version information
--debug: TODO
--reset: Trigger a reset both before and after flashing
--opt: Enable ignore ending empty bytes optimization
--serial iSerial: TODO
--flash=fsize: Where fsize is the size in decimal, octal, or hex followed by an optional multiplier `k' for KB, or `m' for MB. Use a leading “0x” to specify hexadecimal, or a leading zero for octal.

Flash firmware.bin to device


$ st-flash write firmware.bin 0x8000000

Read firmware from device (4096 bytes)


$ st-flash read firmware.bin 0x8000000 0x1000

Erase firmware from device


$ st-flash erase
