STM32MP1OS

A operating system to be running on the STM32MP157C-DK2 development board without the use of any of ST Microelectronic's proprietary binaries, code or tools.

Overview

  • /fsbl : The first stage bootlaoder, loaded by the bootROM

Building an image

ARM32 gcc (e.g arm-none-eabi-gcc or arm-linux-gcc), a standard library such as arm-none-eabi-newlib and genimage is required to build a working image. They can be found either within buildroot or on the AUR.

The build process is as easy as typing make in the command line.

Debugging

For debugging a very up-to-date version of openocd is required to support the stm32mp1. Easiest way to get this is through the openocd-git AUR package. Additionally ARM32 gdb (e.g arm-none-eabi-gdb or arm-linux-gdb) is needed. The project includes a VSCode launch script to make use of the integrated debugger tools.

To start debugging, start the openocd server by running

$ ./start_openocd.sh
