Compile Ubuntu Image from Source Code

This document describes how to compile Ubuntu image from source code.

Preparations

A Ubuntu 22.04 machine

Steps

Step 1. Install dependent 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

Step 2. Obtain the source code

git clone https://github.com/mixtile-rockchip/ubuntu-rockchip.git
cd ubuntu-rockchip

Step 3. Switch to the branch of mixtile-core3588e and build

git checkout mixtile-core3588e
sudo ./build.sh --board=mixtile-core3588e
