Rockchip Debian Docker Cross-Compilation

ArmSoM platform reference based on the supplied Chinese and English Rockchip sources. Match the actual board, SoC, SDK/BSP, kernel and peripherals individually; this does not claim support for every ArmSoM board. Source examples and measurements are not ArmSoM tests. No commands or hardware tests were executed.

Build Debian multi-architecture deb packages on an Ubuntu PC; the package table retains historical source versions.

Source notes: both originals are V1.2.1; all technical chapters retained, with no standalone technical figures. Chinese placeholders are <package_dir>/<pkg_dev>; English uses <package dir>/<package-name>, retained separately, with RU/DE following English. A space-containing placeholder is not an executable path. The Chinese example uses rockchip 。 and a full-width prompt colon; these source anomalies remain, not claimed runnable. Only layout wraps such as dpkg-buildpackage are rejoined. Old Ubuntu versions, package names and “latest” refer to the source period. Container portability still depends on architecture, kernel and devices.

1. Rockchip Docker

Docker is a tool designed to make it easier to create, deploy, and run applications by using containers. Containers allow a developer to package up an application with all of the parts it needs, such as libraries and other dependencies, and ship it all out as one package. By doing so, thanks to the container, the developer can rest assured that the application will run on any other Linux machine regardless of any customized settings that machine might have that could differ from the machine used for writing and testing the code. In a way, Docker is a bit like a virtual machine. But unlike a virtual machine, rather than creating a whole virtual operating system, Docker allows applications to use the same Linux kernel as the system that they’re running on and only requires applications be shipped with things not already running on the host computer. This gives a significant performance boost and reduces the size of the application. And importantly, Docker is open source. This means that anyone can contribute to Docker and extend it to meet their own needs if they need additional features that aren’t available out of the box. Please refer to the following website for Rockchip Docker: docker-rockchip.

2. OS Requirements

To install Docker, you need one of the following 64-bit Ubuntu versions: Jammy 22.04 (LTS) Focal 20.04 (LTS) Bionic 18.04 (LTS) Xenial 16.04 (LTS) Trusty 14.04 (LTS) Note: the dockerfile is used for arm64 Socs by default. The following is used for arm32 Socs: cp dockerfile-32 dockerfile

2.1 Install Docker

Use this command to install the latest version of Docker(replace docker with docker.io in ubuntu 14.04):

sudo apt-get install docker qemu-user-static binfmt-support

Start and run Docker deamon:

sudo service docker start

Build Docker image by dockerfile:

sudo docker build -t rockchip .

Now you get a Docker image named “rockchip” which include a Debian multi-arch cross- compiling environment.

2.2 Build application

Enter docker shell:

sudo docker run -it -v <package dir>:/home/rk/packages rockchip /bin/bash

Start build: For arm 32-bit Socs:

cd /home/rk/packages/<package-name>
DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -rfakeroot -b -d -uc -us -aarmhf
ls ../ | grep *.deb

For arm 64-bit Socs:

cd /home/rk/packages/<package-name>
DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -rfakeroot -b -d -uc -us -aarm64
ls ../ | grep *.deb

2.3 Modify Image

If you want to modify your Docker image, please open a shell by below command:

sudo docker run -it rockchip /bin/bash

After exit from the container, you should use below command to save your changes.

sudo docker commit  <container_id> rockchip

4. Examples

How to generate the libmali-bifrost-g52-g2p0-x11_1.9-1_arm64.deb on libmali

~/work/docker/docker-rockchip$sudo service docker start
~/work/docker/docker-rockchip$sudo docker build -t rockchip .
~/work/docker/docker-rockchip$sudo docker run -it -v /home/wxt/work:/home/rk/packages rockchip /bin/bash
rk@2888134f9c12:/$ cd /home/rk/packages/docker/libmali
rk@2888134f9c12:~/packages/docker/libmali$ DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -rfakeroot -b -d -uc -us -aarm64

The above steps will get the debs for ~/packages/docker/ Rockchip had uploaded some source code for building and generating the deb packages glmark2 libmali mpp rga rkwifbt gstreamer-rockchip
