1. Debian Overview

1.1 What is Debian

Debian is a completely free and open Linux operating system that is widely used on various devices. The reasons for choosing Debian are as follows:

Debian is free software

Debian is made up of free and open source code and will always remain 100% free. Everyone is free to use, modify, and release. You can perform secondary development based on the Debian system built by Rockchip.

Debian is a stable and secure operating system based on Linux.

Debian is an operating system that is widely used on a variety of devices, including laptops, desktops, and servers. Its stability and reliability have been loved by users since 1993. We provide sensible default configurations for each package. Debian developers try to provide security updates for all packages during their lifetime as far as possible.

Debian has widely hardware support.

Most hardware is already supported by Linux kernel. Dedicated hardware drivers can also be used when free software does not provide sufficient support. At present, Rockchip RK3588/RK3568/RK3566/RK3399/RK3288 and other chips have been adapted and supported.

Debian provides smooth updates.

Debian is known for easy and smooth updates during its release cycle, not only that, but also it can easily upgrade to the next major release version. At present, Rockchip has been upgraded from Debian Stretch (9) to Debian Buster (10) and Bullseye (11) versions.

Debian is the seed and base for many other release versions.

Many popular Linux released versions, such as Ubuntu, Knoppix, PureOS, SteamOS, and Tails, have chosen Debian as their software base. Debian provides all the tools, therefore, everyone can use the software package that can meet their own needs to expand the software package in Debian libraries.

Debian project is a community.

Debian is not just a Linux operating system. The software is co-worked by hundreds of volunteers from all over the world. You can become a part of the Debian community even if you are not a programmer or system administrator.

1.2 Supported Debian System Versions

More Debian Long Term Support Version time, please refer to the official website.

2. Debian Quick Strat Guide

2.1 Environment Setup

It is recommended to use Ubuntu 20.04 for compilation. Other Linux versions may need to adjust the software package accordingly. In addition to the system requirements, there are other hardware and software requirements. Hardware requirements: 64-bit system, hard disk space should be greater than 40G. If you do multiple builds, you will need more hard drive space

Software requirements: Ubuntu 20.04 system:

Please install software packages with below commands to setup SDK building environment:

sudo apt-get install git ssh make gcc libssl-dev liblz4-tool expect \
g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support \
qemu-user-static live-build bison flex fakeroot cmake gcc-multilib \
g++-multilib unzip device-tree-compiler ncurses-dev

It is recommended to use the Ubuntu20.04 system or higher version for development. If an error is reported during compilation, you can install the corresponding software package according to the error message.

2.2 Get the Source Code

The source code can be get from the SDK released by Rockchip code server, which is located in the project <SDK>/Debian directory.

2.3 Build

Build the installation packages required for Debian

sudo dpkg -i debian/ubuntu-build-service/packages/*
sudo apt-get install -f

Build Debian

Enter the SDK project and build directly

./build.sh debian

Or go to the Debian/ directory:

cd debian/

Please refer to the current directory readme.md.

(1) Building base Debian system

sudo apt-get install binfmt-support qemu-user-static live-build
sudo dpkg -i ubuntu-build-service/packages/*
sudo apt-get install -f

3. Debian Directory Structure

debian
├── mk-base-debian.sh ##Get Debian base package and build
├── mk-image.sh ##Packag and generate ext4 firmware
├── mk-rootfs-buster/bullseye.sh ##Adapt to Rockchip related hardware
acceleration package
├── mk-rootfs.sh ##Points to the specific Rootfs version, there are currently two
versions of Buster and Bullseye.
├── overlay ##Adapt to the commonly used configuration file of Rockchip platform
├── overlay-debug ##Debugging tools commonly used by the system
├── overlay-firmware ##Storage of some device firmware, such as npu/dp, etc.
├── packages ## Contains pre-built packages for armhf arm64 system adaptation for
hard acceleration
├── packages-patches ##Pre-built packages, based on official patches
├── readme.md ## Documentation guide
└── ubuntu-build-service ##Get the Debian released version,dependent packages and
custom installation related packages from official

The content of the entire directory structure is implemented through shell scripts to obtain the source code of the Linux Debian released versions, build and install the operating system adapted to Rockchip hard acceleration package.

4. Debian Live-build Usage Guide

live build is a group of scripts used to build live system images. The idea behind live build is a tool kit that uses a configuration directory to fully automate and customize all aspects of building live images.

For more introduction, please refer to the official website Live manual.

The source repository of Debian packages (VCS: Git)

live-build-git

The source repository of Debian packages (it is available online)

live-build

lb config

Create auto and config directories and related configuration files in the current directory, and run the auto/config script.

lb clean

run auto/clean scripts

lb build

Build system images according to various configuration scripts in the config directory

4.2 Software Source Settings

The first way:

$ lb config --mirror-bootstrap http://mirrors.ustc.edu.cn/debian \
--mirror-chroot-security http://mirrors.ustc.edu.cn/debian-security/ \
--mirror-chroot-backports http://mirrors.ustc.edu.cn/debian-backports/

chroot mirror: --mirror-chroot, use the value of --mirror-bootstrap by default or create a config/archives/your- repository.list.chroot file with the content of source address. Sources will be added to the /etc/apt/sources.list.d/ directory of the live system.

The Second way:

$ lb config --mirror-binary http://mirrors.ustc.edu.cn/debian \
--mirror-binary-security http://mirrors.ustc.edu.cn/debian-security/

Or create a config/archives/your-repository.list.binary file with the content of source address.

4.3 Customize System Packages

The first way:

Place the required package list in the customization/package-lists directory and name it XXX.list.chroot or XXX.list.binary.

The Second way:

With --package-lists "XXX", the specified package list under /usr/share/live/build/package-lists/ will be used.

After executing lb config, four configuration files, binary, bootstrap, chroot, and common in the config directory will be generated according to the parameters in this script. lb build reads these four configuration files, so you can also make modifications to the parameters in these four files after lb config.

Configuration parameters is in auto/config, for example:

set -e
echo "I: create configuration"
export LB_BOOTSTRAP_INCLUDE="apt-transport-https gnupg"
lb config \
--mirror-bootstrap "http://mirrors.ustc.edu.cn/debian" \
--mirror-chroot "http://mirrors.ustc.edu.cn/debian" \
--mirror-chroot-security "http://mirrors.ustc.edu.cn/debian-security" \
--mirror-binary "http://mirrors.ustc.edu.cn/debian" \
--mirror-binary-security "http://mirrors.ustc.edu.cn/debian-security" \
--apt-indices false \
--apt-recommends false \
--apt-secure false \
--architectures arm64 \
--archive-areas 'main contrib non-free' \
--backports false \
--binary-filesystem ext4 \
--binary-images tar \
--bootappend-live "hostname=linaro-alip username=linaro" \
--bootloader "syslinux" \
--bootstrap-qemu-arch arm64 \
--bootstrap-qemu-static /usr/bin/qemu-aarch64-static \
--cache false \
--chroot-filesystem none \
--compression gzip \
--debootstrap-options "--variant=minbase --include=apt-transport-https,gnupg" \
--distribution bullseye \
--gzip-options '-9 --rsyncable' \
--iso-publisher 'Linaro; http://www.linaro.org/; linaro-dev@lists.linaro.org' \
--iso-volume 'Linaro Bullseye $(date +%Y%m%d-%H:%M)' \
--linux-flavours none \
--linux-packages none \
--mode debian \
--security true \
--system normal \
--updates true

4.3.1 Customized Directory

The customized directory and the files in it can be placed in the corresponding include directory of config/

config/binary_local-includes (take the root directory of the generated image as the root directory) config/chroot_local-includes (take the root directory of the target system as the root directory)

4.3.2 HOOKS

The scripts in config/hooks are run after each stage of live-build has completed. config/binary_local-hooks config/chroot_local-hooks

A new version of live-build will get patches from the live/normal directories.

5.1 mpp

The Media Process Platform (MPP) provided by Rockchip is a general media processing software platform for Rockchip chipset. The platform shields the application software from the complex underlying processing related to chips, and its purpose is to shield the difference between different chips and provide users with a unified video media processing interface (The abbreviation of Media Process Interface is MPI).

Features provided by MPP include:

Video decoding

H.265/H.264/H.263/VP9/VP8/MPEG-4/MPEG-2/MPEG-1/VC1/MJPEG

Video encoding

H.264/VP8/MJPEG

Video processing

Video copying, scaling, color space conversion, field video deinterlace Please refer to the MPP development documentation for more information.

The pre-built packages integrated in Debian are as follows:

5.3 Chromium

chromium/
├── chromium-x11-dbgsym_91.0.4472.164_arm64.deb
└── chromium-x11_91.0.4472.164_arm64.deb

Chromium browser supports H264\VP8\VP9 and other video formats, but does not support H265. At present, Debian has integrated the support of Chromium video hardware decoding, using customized chromium+v4l2 plugin+mpp for efficient hardware decoding.

The main modifications of customized Chromium are as follows:

Modify chromium to enable v4l2 vda support, and related patches add v4l2 mpp plugin Disadvantages: a. Only support vp8, h264, vp9 b. You need to modify and compile chromium (after tuning the complete compilation process of yocto) Currently, we provide chromium wayland patch, support for yocto, buildroot, and a few customers are using it

Chromium version

root@linaro-alip:~# chromium --version Chromium 91.0.4472.164 stable

Command to test hardware decoding:

Use the following command to test:

chromium --no-sandbox file:///usr/local/test.mp4

The test script is in /usr/local/bin/test_dec-chromium.sh:

root@linaro-alip:~# test_dec-chromium.sh
[2588:2588:0214/104846.535688:ERROR:gpu_init.cc(440)] Passthrough is not
supported, GL is egl
...

Linux4.19/5.10 can use the following command to check whether to call the hardware decoding:

echo 0x100 > /sys/module/rk_vcodec/parameters/mpp_dev_debug

Linux4.4 can use the following command to check whether to call the hardware decoding:

echo 0x4 > /sys/module/rk_vcodec/parameters/debug

7. Debian FAQ

7.1 "noexec or nodev" Issue

noexec or nodev issue /usr/share/debootstrap/functions: line 1450:
..../rootfs/ubuntu-build-service/buster-desktop-arm64/chroot/test-dev-null:
Permission denied E: Cannot install into target '/rootfs/ubuntu-build-
service/buster-desktop-arm64/chroot' mounted with noexec or nodev

Solution:

mount -o remount,exec,dev xxx
(The xxx is the project directory path, and then rebuild)

In addition, if other compilation exceptions are encountered, first check that the compilation system used is not the system type of ext2/ext4.

7.2 Failed to Download "Base Debian"

Since building Base Debian needs to visit foreign websites, and when using domestic networks to visit foreign websites, download failures often occur:

Debian uses live build, the mirror source is changed to domestic and can be configured like this:

If the package cannot be downloaded due to other network reasons, there is a pre-built package to share in Baidu Cloud Network Disk, place it in the current directory and execute the next step directly .

7.3 Abnormal Operation Causes an error to Mount /dev

For example, like "askpass command or cannot use one" appears

It may be frequent abnormal operations (CTRL+C) during the compilation process, and the above errors can be fixed by the following methods:

sudo -S  umount  /dev

7.4.1 How to Check the Debian Version of Your System

root@linaro-alip:~# cat /etc/debian_version

7.4.2 How to Check Whether the Debian Display Uses X11 or Wayland

On X11 systems:

$ echo $XDG_SESSION_TYPE
x11

On X11 systems:

7.4.4 The ssh.service Is Abnormal in System

This is a problem of Debian10 or earlier /etc/rc.local, please add the following code:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
# Generate the SSH keys if non-existent
if [ ! -f /etc/ssh/ssh_host_rsa_key ]
then
# else ssh service start in dpkg-reconfigure will fail
systemctl stop ssh.socket||true
dpkg-reconfigure openssh-server
fi
exit 0

7.5 Debian11 Base Package Fails to Build

An error similar to the following will be encountered:

W: Failure trying to run: /sbin/ldconfig
W: See //debootstrap/debootstrap.log for details

It is mainly required that the kernel version of the PC should be 5.10+, which is a bug in the old QEMU. There are two solutions:

The kernel version that comes with the PC must meet the requirements of 5.10+.

The way to check PC Kernel Version:

cat /proc/version
Linux version 5.13.0-39-generic

Update system qemu

Please refer to qemu.
