3. Compile Source

❶ unzip source

1tar xvf rk356x_linux5.10_source-20230905.tar.bz2
2cd rk356x_linux5.10_source\
3sudo tar xvf debian.tar.bz2

❷ set the compile board

1./build.sh -h            //view the build command
2./build.sh device/rockchip/rk356x/BoardConfig-rk3566-evb2-lp4x-v10.mk

or use the command

1./build.sh lunch

print as follow. Select 2

Serial terminal output
processing option: lunch
You're building on Linux
Lunch menu...pick a combo:
0. default BoardConfig.mk

Which would you like? [0]: 2  (BoardConfig-rk3566-evb2-lp4x-v10.mk)

switching to board: /home/EM1126/rk3566_linux_source/device/rockchip/rk356x/BoardConfig-rk3566-evb2-lp4x-v10.mk

❸ compile uboot, kernel, recovery, buildroot

1./build.sh    //compile all in one step

After compile the firmwares are generated in rk356x_linux5.10_source\rockdev

_images/Compile_all.png

User can also use the single-step to compile.

1./build.sh uboot    //compile uboot
2./build.sh kernel   //compile kernel

It will pop out a window about config the IO Power Domain Map when first time compile kernel, you need to configure according to below form.

RK3566-IO-Power-Domain-Map

kernel.img, resource.img and boot.img are generated in directory rk3566_linux_source\kernel.

If only configure the kernel, please complied kernel as follow

1cd kernel
2make ARCH=arm64 menuconfig

The reconfig kernel file is located in kernel\, and the kernel’s default configuration file is kernel\arch\arm64\configs\rockchip_linux_defconfig. So It needs to copy the update from kernel\.config to kernel\arch\arm64\configs\rockchip_linux_defconfig after reconfig.

1source envsetup.sh
2cd buildroot
3make recovery-rebuild
4cd ..
5./build.sh recovery          //compile recovery
6./build.sh rootfs           //compile buildroot

❹ Compile debian11

1cd debian/
2sudo apt-get install binfmt-support qemu-user-static live-build
3sudo dpkg -i ubuntu-build-service/packages/*
4sudo apt-get install -f
5RELEASE=bullseye TARGET=desktop ARCH=arm64 ./mk-base-debian.sh
6VERSION=debug ARCH=arm64 ./mk-rootfs-bullseye.sh
7./mk-image.sh

After compile, will get linaro-rootfs.img in the directory rk356x_linux5.10_source\debian

Compile_debian11

Execute the command to clean the build after compilation.

1sudo ./build.sh cleanall     //clean the build
