Rockchip Debian SDK
Below is the instructions of how to build image for ROCK 3 on a HOST PC.
Get the source code
You need Git to get multiple git repositories to build the image.
Install Git if you don't have it.
sudo apt-get update sudo apt-get install git
Clone the source code
git clone -b stable-4.19-rock3 https://github.com/radxa/rockchip-bsp.git cd rockchip-bsp git submodule init git submodule update
You will get
build kernel README.md rkbin rootfs u-boot
Directories usage introductions:
- build:
- Some script files and configuration files for building u-boot, kernel and rootfs.
- kernel:
- kernel source code, current version is 4.19.193.
- rkbin:
- Prebuilt Rockchip binaries, include first stage loader and ATF(Arm Trustzone Firmware).
- rootfs:
- Bootstrap a Debian based rootfs, support architechture armhf and arm64, support Debian Jessie, Stretch and Buster.
- u-boot:
- u-boot as the second stage bootloader
Update the source code
The rockchip-bsp will be updated all the time, so you can update the source before building the system image.
cd rockchip-bsp git checkout stable-4.19-rock3 git fetch origin git rebase origin/stable-4.19-rock3 git submodule update
Install toolchain from Linaro
wget https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-linux-gnu/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz sudo tar xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz -C /usr/local/ export CROSS_COMPILE=/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu- export PATH=/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin:$PATH
Check if Linaro toolchain is the default choice:
which aarch64-linux-gnu-gcc /usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-gcc
Install other build tools
sudo apt-get install gcc-aarch64-linux-gnu device-tree-compiler libncurses5 libncurses5-dev build-essential libssl-dev mtools sudo apt-get install bc python dosfstools
Build u-boot
Need to checkout branch to stable-4.19-rock3.
Build u-boot with default rock3a-rk3568_defconfig.
./build/mk-uboot.sh rock3a #For ROCK 3A
The generated images will be copied to out/u-boot folder
ls out/u-boot/ idbloader.img rk356x_spl_loader_ddr1056_v1.06.110.bin spi u-boot.itb
Build kernel
Need to checkout branch to stable-4.19-rock3.
Build kernel with default rockchip_linux_defconfig.
./build/mk-kernel.sh rock3a #For ROCK 3A
Change kernel config(optional)
Optionally, if you want to change the default kernel config
cd kernel export ARCH=arm64 export CROSS_COMPILE=aarch64-linux-gnu- make rockchip_linux_defconfig make menuconfig cd .. ./build/mk-kernel.sh rock3a #For ROCK 3A
You will get the kernel image and dtb file
ls out/kernel/ Image rk3568-rock3a.dtb
Make rootfs image
Check out the rootfs source. The repository is https://github.com/radxa/rk-rootfs-build.git and the branch is debian.
To build 32bit rootfs:
export ARCH=armhf
To build 64bit rootfs:
export ARCH=arm64
Building a base debian system by ubuntu-build-service from linaro.
cd rootfs sudo apt-get install binfmt-support qemu-user-static cpio gdisk sudo dpkg -i ubuntu-build-service/packages/* # ignore the broken dependencies, we will fix it next step sudo apt-get install -f RELEASE=buster TARGET=desktop ARCH=arm64 ./mk-base-debian.sh
This will bootstrap a Debian Buster image, you will get a rootfs tarball named linaro-buster-alip-xxxx.tar.gz.
Building the rk-debian rootfs.
RELEASE=buster ARCH=arm64 ./mk-rootfs.sh
Creating the ext4 image(linaro-rootfs.img):
./mk-image.sh
Combine everything into one image
build/mk-image.sh -c rk3568 -t system -r rootfs/linaro-rootfs.img
This will combine u-boot, kernel and rootfs into one image and generate GPT partition table. Output is
out/system.img
Flash the image
