Container for building U-Boot (at least for RK3399, BSP & mainline)

README.md

Container for U-Boot building

At least this was working with Docker. Currently working with Podman.

Really short instructions for building U-Boot

Run something like this:

$ mkdir ~/uboot-workarea && cd ~/uboot-workarea
$ git clone https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/
$ git clone https://gitlab.denx.de/u-boot/u-boot.git/
$ uboot-builder
$ cd trusted-firmware-a/
$ git checkout v2.4
$ make PLAT=rk3399 CROSS_COMPILE=aarch64-linux-gnu- -j24
$ export BL31="$(find ${PWD} -name bl31.elf)" && echo "BL31=${BL31}"
$ cd ../u-boot/
$ git checkout v2021.01
$ make CROSS_COMPILE=aarch64-linux-gnu- rockpro64-rk3399_defconfig
$ make CROSS_COMPILE=aarch64-linux-gnu- all u-boot.itb -j24

That's for RockPro64. Use pinebook-pro-rk3399_defconfig for PBP.

Extremely short instructions for building container image

$ ./build-image.sh
$ mkdir -p ~/bin
$ ln -s "${PWD}/run-image.sh" ~/bin/uboot-builder

build-image.sh

#!/bin/bash
set -e
podman build -t uboot-builder -f ./Dockerfile

# Basic setup, install tools etc.
# Some packages are just from my previous tools containers.
# Some packages just grabbed from: https://wiki.radxa.com/Rockpi4/dev/u-boot
# Added gcc-arm-none-eabi, rename, bison, git, python3 and python-pyelftools.
# Should be able to build both BSP and mainline uboot for RK3399 devices.
# And TFA too.
