Compiling RK3568 SDK Guide
Create Debian System Image (Rockchip Official)
Host System Requirements
Debian 11 (bullseye) or Ubuntu 20.04. with Memory >= 16GB and disk space >= 100GB.
Compiling Requirements
Install the necessary packages on Debian/Ubuntu systems:
sudo apt-get install build-essential flex bison genext2fs
Get SDK Repo files by tarball
Download your SDK: (replace url with your given url)
wget https://dl.photonicat.com/repos/rk3568-debian-source-20220927.tar.xz
Build system image
Run the command below:
./build.sh
The output path is rockdev, system image path is rockdev/pack
Build Debian/Ubuntu system image (mainline u-boot & kernel)
Check README in https://github.com/photonicat/rockchip_rk3568_linux_mainline for building system image.
Build OpenWRT
Photonicat image contains following packages：
- OpenWRT (within rk3568-linux-sdk which builds bootloader, uboot, kernel and OpenWRT)
- pcat-manager (within rk3568-linux-sdk)
- pcat-manager-web (python closed source. install manually: e.g: https://dl.photonicat.com/repos/openwrt/volatile/pcat-manager-web_1.0.9-0_aarch64_cortex-a53.ipk, we need to change luci listen port to 8080.)
- quectel-cm (within rk3568-linux-sdk)
rk3568-linux-sdk will fetch uboot, kernel, openwrt, and copmile them in one build script.
In addition to default packages we have 3 more package for power and modem manager.
- modem/power_manager (written in c)
- web interface for displaying mobile modem and battery info. (written in python)
- c program modem watchdog
Host System Requirements
Debian 11 (bullseye) or Ubuntu 20.04, other distributions may work but not tested.
Compiling Requirements
Please a NORMAL USER, not root
On Debian/Ubuntu systems, install the packages:
sudo apt update sudo apt upgrade -y sudo apt install -y ack antlr3 asciidoc autoconf automake autopoint binutils bison build-essential \ bzip2 ccache cmake cpio curl device-tree-compiler fastjar flex gawk gettext gcc-multilib g++-multilib \ git gperf haveged help2man intltool libc6-dev-i386 libelf-dev libglib2.0-dev libgmp3-dev libltdl-dev \ libmpc-dev libmpfr-dev libncurses5-dev libncursesw5-dev libreadline-dev libssl-dev libtool lrzsz \ mkisofs msmtp nano ninja-build p7zip p7zip-full patch pkgconf python2.7 python3 python3-pyelftools \ libpython3-dev qemu-utils rsync scons squashfs-tools subversion swig texinfo uglifyjs upx-ucl unzip \ vim wget xmlto xxd zlib1g-dev
Get repo files
Get repo files from Github (non-root user):
git clone https://github.com/photonicat/rockchip_rk3568_openwrt.git cd rockchip_rk3568_openwrt
Config build target
Run the command below:
./scripts/feeds update -a ./scripts/feeds install -a cp ./configs/base_defconfig .config
Build system image
Run the command below:
make
The output path is bin/targets/rockchip/armv8/, system image will be named like photonicatwrt-23.04-rxxxx+xx-xxxxxxxxx-rockchip-armv8-ariaboard_photonicat-squashfs-sysupgrade.img.gz
make menuconfig
save and re-run build process again.
IPKs will be under:
bin/targets/rockchip/armv8/packages/
Build your own package, modules on OpenWRT (Optional)
Use
make menuconfig
to select
<M> package_name
for your desired package(s).
If you want to include your own packages to system image, see OpenWRT official documents https://openwrt.org/docs/guide-developer/packages for help.
Flash system images to the onboard eMMC
Prepare update tools and files:
git clone https://github.com/rockchip-linux/rkdeveloptool.git cd rkdeveloptool sudo apt-get install libudev-dev libusb-1.0-0-dev dh-autoreconf aclocal autoreconf -i autoheader automake --add-missing ./configure make wget https://dl.photonicat.com/images/MiniLoaderAll.bin
Enter the firmware update mode, use A-to-A cable to connect USB OTG port to PC, and use the command below:
gunzip photonicatwrt-23.04-rxxxx+xx-xxxxxxxxx-rockchip-armv8-ariaboard_photonicat-squashfs-sysupgrade.img.gz #Replace file name with the one you get indeed. sudo ./rkdeveloptool db MiniLoaderAll.bin sudo ./rkdeveloptool wl 0 photonicatwrt-23.04-rxxxx+xx-xxxxxxxxx-rockchip-armv8-ariaboard_photonicat-squashfs-sysupgrade.img sudo ./rkdeveloptool rd
How to modify your own version of kernel for openwrt
Compile rockchip_rk3568_openwrt with above steps.
Modify:
- DTB: https://github.com/photonicat/rockchip_rk3568_openwrt/blob/master/target/linux/rockchip/files/arch/arm64/boot/dts/rockchip/rk3568-photonicat.dts
- kernel patches: (we need to add/ modify your version of kernel patches into this dir and recompile): https://github.com/photonicat/rockchip_rk3568_openwrt/tree/master/target/linux/rockchip/patches-6.1
Recompile and done.
