3. Compile Source
Step 1, unzip the source
tar xvf rk356x_linux5.10_source-20230905.tar.bz2 // unzip source
cd rk356x_linux5.10_source\
sudo tar xvf debian.tar.bz2
./build.sh -h // view the build command
Step 2, configure
./build.sh lunch // configure
Print out as follow. Select 2
processing option: lunch
You're building on Linux
Lunch menu...pick a combo:
0. default BoardConfig.mk
1. BoardConfig-rk3566-evb2-lp4x-v10-32bit.mk
2. BoardConfig-rk3566-evb2-lp4x-v10.mk
3. BoardConfig-rk3568-evb1-ddr4-v10-32bit.mk

Step 3, compile uboot, kernel, recovery, buildroot
./build.sh //Compile all in one step
After compile the firmwares are generated in rk356x_linux5.10_source\rockdev
User can also single-step compile.
./build.sh uboot //compile uboot
./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.
kernel.img, resource.img and boot.img are generated in directory
rk3566_linux_source\kernel.
If only configure the kernel, please complie as follow
cd kernel
make ARCH=arm64 menuconfig
The reconfig kernel file is located in kernel\. The kernel 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.
source envsetup.sh
cd buildroot
make recovery-rebuild
cd ..
./build.sh recovery //compile recovery
./build.sh rootfs //compile buildroot
Clean the build after compilation
sudo ./build.sh cleanall //Clean the build
