3 Compile Source

Step 1, unzip the source and set the compile board
$ tar xvf sdk-11.0.tar.gz
$ cd sdk-11.0
Step 2, compile uboot
$ cd u-boot
$ ./make.sh rk3568
Step 3, compile the kernel
$ cd kernel
$ make ARCH=arm64 rockchip_defconfig rk356x_evb.config android-11.config
$ make ARCH=arm64 rk3568-evb2-lp4x-v10.img -j24
Android11.0 kernel.img and resource.img are included in boot.img, if you only update the kernel, you
can compile the kernel separately with the following command. After compiling, you can directly flash
the boot.img under kernel directory.
$ make ARCH=arm64 rockchip_defconfig rk356x_evb.config android-11.config
$ make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3568_r/boot.img rk3568-evb2-lp4x-v10.img
-j24
Step 4, compile Android
$ source build/envsetup.sh
$ lunch rk3568_r-userdebug
$ make -j12
Step 5, Generated image file
$ ./mkimage.sh
$ ./build.sh -u (packaged in the update.img)
$ cd rockdev
$ ls
Images and update.img are generated in current directory.
