The project is a set of patches and configuration files to build bootloader and Linux based system image with a minimal root file system for the following collections of STM32 Discovery boards:
- 32F429IDISCOVERY Discovery kit [PENDING]
- 32F746GDISCOVERY Discovery kit [READY]
- 32F769IDISCOVERY Discovery kit [PENDING]
- STM32MP157A-DK1 / STM32MP157C-DK2 Discovery kits [PENDING]
The following versions of tools are using in the project:
- Buildroot v2020.05
- U-Boot v2018.07
- Linux kernel v5.4.46
$ make bootstrap- downloading source code and copying configuration of a development board$ make build- compiling bootloader and Linux based system image with a minimal root file system$ make tftp- copying device tree binary and kernel image to the TFTP destination folder$ make flash_bootloader- flashing SPL and U-Boot to a development board via OpenOCD with ST-LINK$ make clean- clearing temporary folders for downloading and compiling source code
System image and device tree binary are loading over a network with the blue user button held down during development board startup. The default IP addresses of TFTP server and development kit are 10.0.222.9 and 10.0.222.100 respectively. To change the IP address edit the U-Boot environment patch.
