How to flash a board using a bash/python script

[CHech.1]

Hi,

I'm using an STM32L496G board, currently flashing it through CubeMX/Touchgfx Designer.

In the future, i'd like to be able to flashthe board by running a bash/python/other script from a linux machine.

The board will be connected to the linux machine via uart.

I'm not sure how to do that, and I wasn't able to find helpful instructions online.

I'd appreciate your help.

Thank you!

There are command line tools available: openOCD and stlink-tools.

STM32CubeProgrammer has a command line interface (CLI) available as well. That's probably the simplest.

My solution:

(script is obviously very basic and needs error checking etc.)

import os
 
CUBE_PROGRAMMER_CLI_PATH = 'C:\\Program Files\\STMicroelectronics\\STM32Cube\\STM32CubeProgrammer\\bin'
FILE_TO_DOWNLOAD_NAME = 'MyFlashes\\MyFile.elf'
CONNECTION_PORT = 'swd'
EXTERNAL_LOADER_PATH = 'MX25R6435F_STM32L496G-DISCO.stldr'
 
 
def main():
    os.chdir(CUBE_PROGRAMMER_CLI_PATH)
    os.system(f"STM32_Programmer_CLI.exe -c port={CONNECTION_PORT} -w {FILE_TO_DOWNLOAD_NAME} -v -el {EXTERNAL_LOADER_PATH}")
    os.system(f"STM32_Programmer_CLI.exe -c port={CONNECTION_PORT} -hardRst")
 
if __name__ == '__main__':
    main()
