LonganPi-3H-SDK

Scripts and blobs for LonganPi 3H image build.

Tested on Ubuntu 22.04.2 LTS and WSL2 Ubuntu-22.04

Command Line Build

  1. Install some dependencies
sudo apt update
sudo apt install qemu-user-static gcc-aarch64-linux-gnu mmdebstrap git binfmt-support make build-essential  bison flex make gcc libncurses-dev debian-archive-keyring swig libssl-dev bc python3-setuptools
  1. Build arm-trusted-firmware
./mkatf.sh
  1. Build uboot
./mkuboot.sh
  1. Build kernel
./mklinux.sh
  1. Build rootfs
# for Debian desktop
sudo ./mkrootfs-debian-gui.sh

# for Debian without gui
# sudo ./mkrootfs-debian-cli.sh

# for Ubuntu without gui
# sudo ./mkrootfs-ubuntu-cli.sh

Docker build

Note: The container to execute the actual image build is run with the --privileged flag (due to quemu usage). If you cannot run privileged containers in your environment then the docker build will most likely not work for you.

If you have make and docker installed you can also build the image with docker. The Makefile has two utility targets and two main group of targets that you can run. An out/ folder will be created which is mounted into the container and the output files will be copied in there.

Utility Targets

# Just build the build-container
make build

# remove the out/ directory
make clean

Targets to build the root FS and boot files

# Build Debian desktop root FS
make debian-gui

# Build Debian root FS without gui
make debian-cli

# Build Ubuntu root FS without gui
make ubuntu-cli

Targets to build the full image

# Build Debian desktop image
make debian-gui-img

# Build Debian image without gui
make debian-cli-img

# Build Ubuntu image without gui
make ubuntu-cli-img

From there you can follow https://wiki.sipeed.com/hardware/en/longan/h618/lpi3h/7_develop_mainline.html to create a boot card.
