5. ubuntu-rockchip Introduction

Ubuntu Rockchip is a community project that ports Ubuntu to Rockchip hardware, with the goal of providing a stable and fully functional environment. ubuntu-rockchip

5.1 Supported ArmSoM products

Continuously updated...

5.2 Supported kernel versions

Linux version: 5.10.160 arm64
Linux version: 6.1.43 arm64

5.3 Directory structure

LICENSE: GNU, GPL General Public License
README.md: Project description document
build: Download from the Internet The source code of uboot, kernel, and rootfs downloaded by git clone is placed in this directory
build.sh: script for compiling the entire image
config: board-level configuration, kernel configuration file
docker: docker-related
images: storage of compiled firmware
overlay: bsp customized operation, overlay
packages: uboot-related information
scripts: scripts for building the system, mainly downloading source code from the Internet and compiling and packaging it into a deb package, and packaging each component: uboot, kernel, rootfs into a complete firmware

5.4 Development environment construction

Please use Ubuntu 22.04 and above servers, and then install the following software packages:

sudo apt-get install -y build-essential gcc-aarch64-linux-gnu bison \
qemu-user-static qemu-system-arm qemu-efi u-boot-tools binfmt-support \
debootstrap flex libssl-dev bc rsync kmod cpio xz-utils fakeroot parted \
udev dosfstools uuid-runtime git-lfs device-tree-compiler python2 python3 \
python-is-python3 fdisk bc debhelper python3-pyelftools python3-setuptools \
python3-distutils python3-pkg-resources swig libfdt-dev libpython3-dev

5.5 Compile the entire board-level firmware

Pull the source code and compile:

git clone https://github.com/Joshua-Riek/ubuntu-rockchip
cd ubuntu-rockchip
sudo ./build.sh --board=armsom-sige7

The compiled firmware is stored in the directory: armsom-build/images:

5.6 Recompile the complete firmware after modifying the kernel locally

Delete the deb packages of linux-headers and linux-image:

cd ./armsom-build/build
sudo rm -rf linux-headers-5.10.160_5.10.160-1_arm64.deb
sudo rm -rf linux-image-5.10.160_5.10.160-1_arm64.deb

Modify the kernel in the local kernel source code: armsom-build\build\linux-rockchip
Recompile the complete firmware

sudo ./build.sh --board=armsom-sige7
