Build DockerFile

   radxa$ docker build -t android-builder:11.x --build-arg USER_ID=`id -u` --build-arg GROUP_ID=`id -g` $(which-dir-dockerfile-in)

Download source code

   $ mkdir rock-android11
   $ cd rock-android11

Then run:

  radxa:rock-android11 $ repo init -u https://github.com/radxa/manifests.git -b Android11_Radxa_rk11 -m rockchip-r-release.xml
  radxa:rock-android11 $ repo sync -d --no-tags -j4

Build

Use all-in-one build script

  radxa:rock-android11 $ source build/envsetup.sh
  
  # for Rock 3A
  radxa:rock-android11 $ lunch rk356x_rock_3a_r-userdebug
  # for Rock 3A if you want a box software
  radxa:rock-android11 $ lunch rk356x_rock_3a_box-userdebug
  # for Rock 3B
  radxa:rock-android11 $ lunch rk356x_rock_3b_r-userdebug
  # for Rock CM3 IO
  radxa:rock-android11 $ lunch rk356x_rock_cm3_r-userdebug
  
  radxa:rock-android11 $ ./build.sh -UACKup
  # get images from IMAGE directory

Step by step Build

If you dont' want to use "Use all-in-one build script", you can follow this way to build image step by step.

Setup board environment

  # for Rock 3A
  radxa:rock-android11 $ export PRODUCT_NAME="rk356x_rock_3a_r"
  radxa:rock-android11 $ export PRODUCT_UBOOT_CONFIG="radxa_rock_3a_toybrick"
  radxa:rock-android11 $ export PRODUCT_KERNEL_CONFIG="rockchip_defconfig"
  radxa:rock-android11 $ export PRODUCT_KERNEL_DTS="rk3568-rock-3a"

  # for Rock 3A box software
  radxa:rock-android11 $ export PRODUCT_NAME="rk356x_rock_3a_box"
  radxa:rock-android11 $ export PRODUCT_UBOOT_CONFIG="radxa_rock_3a_toybrick"
  radxa:rock-android11 $ export PRODUCT_KERNEL_CONFIG="rockchip_defconfig"
  radxa:rock-android11 $ export PRODUCT_KERNEL_DTS="rk3568-rock-3a"

  # for Rock 3B
  radxa:rock-android11 $ export PRODUCT_NAME="rk356x_rock_3b_r"
  radxa:rock-android11 $ export PRODUCT_UBOOT_CONFIG="radxa_rock_3a_toybrick"
  radxa:rock-android11 $ export PRODUCT_KERNEL_CONFIG="rockchip_defconfig android-11.config rock_3b.config"
  radxa:rock-android11 $ export PRODUCT_KERNEL_DTS="rk3568-rock-3b"

  # for Rock CM3 IO
  radxa:rock-android11 $ export PRODUCT_NAME="rk356x_rock_cm3_r"
  radxa:rock-android11 $ export PRODUCT_UBOOT_CONFIG="rk3566"
  radxa:rock-android11 $ export PRODUCT_KERNEL_CONFIG="rockchip_defconfig android-11.config rockcm3io.config"
  radxa:rock-android11 $ export PRODUCT_KERNEL_DTS="rk3566-rock-cm3io"

Build u-boot

  radxa:rock-android11 $ cd u-boot
  radxa:rock-android11/u-boot $ make clean
  radxa:rock-android11/u-boot $ make mrproper
  radxa:rock-android11/u-boot $ make distclean
  radxa:rock-android11/u-boot $ ./make.sh ${PRODUCT_UBOOT_CONFIG}
  radxa:rock-android11 $ cd -

The generated images are idbloader.img , and uboot.img

Building kernel

  radxa:rock-android11 $ cd kernel
  radxa:rock-android11/kernel $ ADDON_ARGS="CC=../prebuilts/clang/host/linux-x86/clang-r383902b/bin/clang LD=../prebuilts/clang/host/linux-x86/clang-r383902b/bin/ld.lld"
  radxa:rock-android11/kernel $ make clean
  radxa:rock-android11/kernel $ make $ADDON_ARGS ARCH=arm64 ${PRODUCT_KERNEL_CONFIG}
  radxa:rock-android11/kernel $ make $ADDON_ARGS ARCH=arm64 ${PRODUCT_KERNEL_DTS}.img -j$(nproc)
 
  radxa:rock-android11 $ cd -


Building AOSP

  radxa:rock-android11 $ source build/envsetup.sh
  radxa:rock-android11 $ lunch ${PRODUCT_NAME}-userdebug
  radxa:rock-android11 $ make -j$(nproc)

It takes a long time, take a break and wait...


Make images

  radxa:rock-android11 $ rm -rf rockdev
  radxa:rock-android11 $ ln -s RKTools/linux/Linux_Pack_Firmware/rockdev .
  radxa:rock-android11 $ ./mkimage.sh


Pack Image

  radxa:rock-android11 $ cd rockdev
  radxa:rock-android11/rockdev $ rm -rf Image
  radxa:rock-android11/rockdev $ ln -s Image-${PRODUCT_NAME} Image

1. RkUpdate Image

  radxa:rock-android11/rockdev $ ./mkupdate_rk356x.sh

The images under rockdev/ are `update.img`

2. gpt Image

  radxa:rock-android11/rockdev $ ./android-gpt.sh
