st-flash - Flash binary files to STM32 device
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.
The STLink device to use can be specified using the --serial parameter.
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 : Serial number of ST-LINK device to use
--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
st-util(1), st-info(1)
