1 Introduction to Buildroot

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. It contains a boot-loader, kernel, rootfs, various libraries and utilities(e.g. qt, gstreamer, busybox etc).

FriendlyELEC's Buildroot is based on Rockchip's version which is made with linux-sdk and maintained with git. FriendlyELEC's version is synced with Rockchip's version;


Here is what Buildroot for rockchip looks like

After extract the file you can use either dd or the win32image utility to flash the image to an SD card.

3 User Name and Password

User name: root
Password: rockchip

To change the password, please modify the following file: 

buildroot/configs/rockchip/network.config      # branch: rockchip-kernel4.19
buildroot/configs/rockchip/base/common.config  # branch: rockchip-kernel5.10 / rockchip-kernel6.1

4 Connect WiFi

  • Edit /etc/wpa_supplicant.conf, fill in the ssid and psk with the WiFi information you want to connect to
  • Start the wpa_supplicant process with the following command
wpa_supplicant -B -i wlan0 -c /etc/wpa_supplicant.conf
  • If there is no error, you can check the ip address with the command 'ifconfig wlan0'

5 Obtain Source Code

5.1 Install repo Utility

Install the repo utility: 

git clone https://github.com/friendlyarm/repo --depth 1
sudo cp repo/repo /usr/bin/

Install the git-lfs utility: 

sudo apt update
sudo apt install git-lfs

5.2 Download Source Code

You can retrieve a project's source code in either of the following two ways. The first works better with Mainland Chinese users:

5.2.1 1: Retrieve Repo Package from NetDrive

Download link: RK3588 RK3568 RK3399 RK3328
File location: '07_Source codes'/buildroot-rkXXXX-YYYYMMDD.tar (YYYYMMDD stands for the data when the package is generated)
After you get a tar package, untar it and run the following command to extract it: 

tar xvf /path/to/netdrive/'07_Source codes'/buildroot-rkXXXX-YYYYMMDD.tar
cd buildroot-rkXXXX
repo sync -l --no-clone-bundle
(cd external && ./get_libgenmeshlib.sh)

If you want to get the latest official source code you can run the following commands: 

cd buildroot-rkXXXX
repo sync --no-clone-bundle

5.2.2 2: Retrive Repo Package from Github

5.2.2.1 Buildroot for RK3588
mkdir buildroot-rk3588
cd buildroot-rk3588
repo init -u https://github.com/friendlyarm/buildroot_manifests \
    -b rockchip-kernel6.1 -m rk3588.xml --repo-url=https://github.com/friendlyarm/repo \
    --no-clone-bundle
repo sync -c --no-clone-bundle
(cd external && ./get_libgenmeshlib.sh)
5.2.2.2 Buildroot for RK3568
mkdir buildroot-rk3568
cd buildroot-rk3568
repo init -u https://github.com/friendlyarm/buildroot_manifests \
    -b rockchip-kernel6.1 -m rk3568.xml --repo-url=https://github.com/friendlyarm/repo \
    --no-clone-bundle
repo sync -c --no-clone-bundle
(cd external && ./get_libgenmeshlib.sh)
5.2.2.3 Buildroot for RK3399
mkdir buildroot-rk3399
cd buildroot-rk3399
repo init -u https://github.com/friendlyarm/buildroot_manifests \
    -b rockchip-kernel4.19 -m rk3399.xml --repo-url=https://github.com/friendlyarm/repo \
    --no-clone-bundle
repo sync -c --no-clone-bundle
5.2.2.4 Buildroot for RK3328
mkdir buildroot-rk3328
cd buildroot-rk3328
repo init -u https://github.com/friendlyarm/buildroot_manifests \
    -b rockchip-kernel4.19 -m rk3328.xml --repo-url=https://github.com/friendlyarm/repo \
    --no-clone-bundle
repo sync -c --no-clone-bundle

5.2.3 Get Latest Version with Sync

repo sync -c --no-clone-bundle

If your network connection is broken during sync you can run the following script to do it: 

#! /bin/bash
repo sync -c --no-clone-bundle
while [ $? -ne 0 ]; 
do  
    repo sync -c --no-clone-bundle
done

6 Compile Source Code

6.1 Setup Development Environment

You need a host PC running a 64-bit Ubuntu 20.04 system and run the following command on the PC: 

wget -O - https://raw.githubusercontent.com/friendlyarm/build-env-on-ubuntu-bionic/master/install.sh | bash

6.2 Build buildroot in Docker container

Please use the Docker image provided by this link, for details, please refer to the README document：
docker-cross-compiler-novnc

6.3 Get Help Info

Run the build.sh script without any options it will print the help information: 

./build.sh

Let's take RK3588 as an example, the help information will be presented as follows: 

USAGE: ./build.sh <parameter>
 
# Select CPU model:
  ./build.sh rk3588
 
# Select Module:
  ./build.sh all                -compile all
  ./build.sh uboot              -compile uboot
  ./build.sh kernel             -compile kernel
  ./build.sh buildroot          -compile buildroot
  ./build.sh sd-img             -generate an image for an sd card
  ./build.sh emmc-img           -generate an image for emmc (the generated image should be flased to an SD card and then flashed to emm with this SD card)
# Clean:
  ./build.sh clean              -remove old images
  ./build.sh cleanall

6.4 Auto Compile

For a first time compilation you need to select an board: 

./build.sh rk3588

After the script is done successfully all components including a u-boot, a kernel and a buildroot will be compiled, and an image file will be generated.

6.5 Compile Individual Component

6.5.1 kernel

./build.sh kernel

6.5.2 u-boot

./build.sh uboot

6.5.3 buildroot

./build.sh buildroot

6.6 Generate Image for SD Card

sudo ./build.sh sd-img

If an img file is generated successfully you will see the following messages. You can use the "dd" command to flash the img file to an SD card. Note: you will need to replace "/dev/sdX" with the actual device name which your system recognizes the device as:

Run the following for sdcard install:
    sudo dd if=out/buildroot_20211213_rk3588_arm64_sd.img bs=1M of=/dev/sdX

6.7 Generate emmc (eflasher) Image

sudo ./build.sh emmc-img

If an img file is generated successfully you will see the following messages. You can use the "dd" command to flash the img file to an SD card. Note: you will need to replace "/dev/sdX" with the actual device name which your system recognizes the device as:

Run the following for sdcard install:
    sudo dd if=out/buildroot_20211213_rk3588_arm64_eflasher.img bs=1M of=/dev/sdX

Use this SD card to boot the eflasher system and run eflasher commands to install an OS to emmc. After installation is done, take off the SD card of the board and boot your system buildroot will load from eMMC.

7 Customize Buildroot

7.1 Structure of Directories

├── buildroot-xxyyzz
│   ├── buildroot -> buildroot's source code
│   └── toolchain -> cross-compiler, used for compiling a u-boot and kernel
│   ├── build.sh -> build script
│   ├── device/friendlyelec -> configuration file for friendlyelec boards
│   ├── kernel -> kernel
│   └── u-boot -> u-boot
│   └── app -> rockchip app
│   └── external -> rockchip buildroot package
│   └── rkbin -> rockchip loader binaries
│   └── scripts -> script files for generating an img

7.1.1 Update Buildroot Configurations

  • List Available Configurations
cd buildroot
make list-defconfigs

The configuration of FriendlyELEC RK3588:
configs/rockchip_rk3588_defconfig

  • Update Configurations Using menuconfig
make rockchip_rk3588_defconfig
make menuconfig
make savedefconfig
cp .defconfig configs/rockchip_rk3588_defconfig
  • Recompile
cd ../
./build.sh buildroot

7.2 Customize File System

Put the file in device/friendlyelec/misc-files, then repackage the img: 

sudo ./build.sh sd-img
sudo ./build.sh emmc-img

7.3 Update U-boot and Kernel

You can do it by directly updating the files in the u-boot and kernel directories.

7.4 Use Cross Compiler in SDK

export PATH=$PWD/buildroot/output/rockchip_rk3588/host/bin/:$PATH
aarch64-buildroot-linux-gnu-g++ -v

Version information:
gcc version 12.3.0 (Buildroot -gcfced2b28e)

8 Enabling ADB

Enable on Startup 

mv /etc/init.d/K50usbdevice.sh /etc/init.d/S50usbdevice.sh
reboot

Enable Temporarily 

usbdevice-wrapper start

9 Q&A

9.1 Generate Image File for Flashing with USB Type-C

After you run the "build.sh emmc-img" command a "buildroot" directory will be generated under the "scripts/sd-fuse" directory. You can use the android_tools to load all the files under this "buildroot" directory.
