Setting up the environment
Debian-like systems
sudo apt install git gcc-arm-none-eabi openocd
If you see "not found" message please add "extended" repository to /etc/apt/sources.list.
Windows
Prebuilt "arm-gnu-toolchain" Windows package could be found on an official "ARM developer" repository: https://developer.arm.com/downloads/-/arm-gnu-toolchain-downloads
-or- you can build it from sources, but it could be a little bit tricky.
If you wish to use "STM32CubeProgrammer" to write your programs to a microcontroller's flash memory - download and install "STM32CubeProgrammer" from official STMicroelectronics site: https://www.st.com/en/development-tools/stm32cubeprog.html
-or-
If you wish to use "openocd" debugger - it is here: https://openocd.org/pages/getting-openocd.html
Compiling
On Linux, cd to a project's directory (where "Makefile" located) and type "make". The script will put you firmware file a.bin to the "bin" directory.
On Windows please use "_compile.bat" script in a project's directory or type the commands manually like shown in the script.
Flashing
After a successful program compilation connect your device to a ST-Link programmer to write it to a microcontroller's memory.
On Linux, cd to a project's directory and use _write.sh script or an "openocd" command from it. To make the script file executable please type
chmod +x _write.sh
On Windows please change the path to a "STM32_Programmer_CLI.exe" file in a "_write.bat" script. Usually this file could be found in the "Program Files" directory on a drive "C:" where "STMCubeProgrammer" software installed.
The script will automatically write your program and start it execution.
