  • The sd-fuse is a helper script to make bootable SD card image.

1.2 Build kernel linux-v5.10.y

Clone the repository to your local drive then build: 

git clone https://github.com/friendlyarm/kernel-rockchip --single-branch --depth 1 -b nanopi5-v5.10.y_opt kernel-rockchip
cd kernel-rockchip
export PATH=/opt/FriendlyARM/toolchain/11.3-aarch64/bin/:$PATH
touch .scmversion
# Configuring the Kernel
# Load default configuration
make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 nanopi6_linux_defconfig
# Optionally, load configuration for FriendlyWrt
# make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 nanopi6_linux_defconfig friendlywrt.config
# Optionally, if you want to change the default kernel config
# make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 menuconfig
# Start building kernel
make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 nanopi6-images -j$(nproc)
# Start building kernel modules
mkdir -p out-modules && rm -rf out-modules/*
make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 INSTALL_MOD_PATH="$PWD/out-modules" modules -j$(nproc)
make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 INSTALL_MOD_PATH="$PWD/out-modules" modules_install
KERNEL_VER=$(make CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64 kernelrelease)
[ ! -f "$PWD/out-modules/lib/modules/${KERNEL_VER}/modules.dep" ] && depmod -b $PWD/out-modules -E Module.symvers -F System.map -w ${KERNEL_VER}
(cd $PWD/out-modules && find . -name \*.ko | xargs aarch64-linux-strip --strip-unneeded)

The generated files:

kernel.img resource.img boot.img This img is deprecated The kernel modules are located in the out-modules directory

Apply kernel:
Please click on #Apply u-boot and the kernel

1.3 Build u-boot v2017.09

Clone the repository to your local drive then build: 

git clone https://github.com/friendlyarm/rkbin --single-branch --depth 1 -b nanopi6
git clone https://github.com/friendlyarm/uboot-rockchip --single-branch --depth 1 -b nanopi6-v2017.09
export PATH=/opt/FriendlyARM/toolchain/11.3-aarch64/bin/:$PATH
cd uboot-rockchip/
./make.sh nanopi6

After the compilation, the following files will be generated:

uboot.img rk3588_spl_loader_v1.08.111.bin (aka MiniLoaderAll.bin)

Apply u-boot:
Please click on #Apply u-boot and the kernel

1.4 Apply u-boot and the kernel

1.4.1 Install to target board

RK3588 uses GPT partitions by default, you can use the dd command, but be careful to choose the right output device:

  • The SD/TF Card device node: /dev/mmcblk0
  • The eMMC device node: /dev/mmcblk2


Use the 'parted' command to view the partition layout: 

parted /dev/mmcblk2 print

Sample outputs: 

Model: MMC A3A551 (sd/mmc)
Disk /dev/mmcblk2: 31.0GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:
 
Number  Start   End     Size    File system  Name      Flags
 1      8389kB  12.6MB  4194kB               uboot
 2      12.6MB  16.8MB  4194kB               misc
 3      16.8MB  21.0MB  4194kB               dtbo
 4      21.0MB  37.7MB  16.8MB               resource
 5      37.7MB  79.7MB  41.9MB               kernel
 6      79.7MB  113MB   33.6MB               boot
 7      113MB   147MB   33.6MB               recovery
 8      147MB   31.0GB  30.9GB  ext4         rootfs

as shown above, the resource partition is located at 4 and the kernel partition is located at 5. Use the dd command to write the resource.img and kernel.img files to these partitions, the commands are as follows: 

dd if=resource.img of=/dev/mmcblk2p4 bs=1M
dd if=kernel.img of=/dev/mmcblk2p5 bs=1M

If you want to update u-boot: 

dd if=boot.img of=/dev/mmcblk2p1 bs=1M

To update new driver modules, copy the newly compiled driver modules to the appropriate directory under /lib/modules.

1.4.2 Packaging and creating an SD image

To create a new OS image file, you need to use the "sd-fuse" packaging tool.

"sd-fuse" is a collection of scripts that can be used to create bootable SD card images for FriendlyElec boards. Its main features include:

  • Creation of root filesystem images from a directory
  • Building of bootable SD card images
  • Simple compilation of kernel, U-Boot, and third-party drivers

Please click on the following link to find out more:

Kernel version Packaging Tool
linux v5.10.y sd-fuse_rk3588
1.4.3 USB flashing
1.4.3.1 Linux

To flash U-Boot and kernel using the "upgrade_tool" tool, please use the following command: 

sudo upgrade_tool ul MiniLoaderAll.bin
sudo upgrade_tool di -p parameter.txt
sudo upgrade_tool di uboot uboot.img
sudo upgrade_tool di resource resource.img
sudo upgrade_tool di kernel kernel.img
sudo upgrade_tool RD

Note: "upgrade_tool" is a command-line tool provided by Rockchip for Linux operating systems (Linux_Upgrade_Tool).

2 Building AOSP from source

2.1 Download source from the netdrive

Netdisk URL: Click here
File location on netdisk："07_Source codes/rk35xx-android12-xxxxxxx-YYYYMMDD.tgz" (YYYYMMDD represents the date of the package, and xxxxxxx represents the final commit-id)
Unzip and fetch updates: 

tar xzf '/path/to/netdisk/07_Source codes/rk35xx-android12-xxxxxxx-YYYYMMDD.tgz'
cd rk35xx-android12
git pull

2.2 Tablet profile build

echo "ROCKCHIP_DEVICE_DIR := device/rockchip/rk3588/nanopi6" > .rockchip_device.mk
# export INSTALL_GAPPS_FOR_TESTING=yes  # include google apps
. setenv.sh
./build.sh -FMu

2.3 TV profile build

echo "ROCKCHIP_DEVICE_DIR := device/rockchip/rk3588/nanopi6_box" > .rockchip_device.mk
# export INSTALL_GAPPS_FOR_TESTING=yes  # include google apps
. setenv.sh
./build.sh -FMu

2.4 Running the build

After the Android compilation is completed, the image file will be stored in the rockdev/Image-aosp_nanopi3 subdirectory of the Android source code directory.

2.4.1 USB Flashing

Use the rockchip tool to flash the following file: rockdev/Image-aosp_nanopi3/update.img

2.4.2 SD-to-eMMC Flashing

Refer to the following steps：
1) Insert the SD card of the eflasher system into the host;
2) Copy the files in the rockdev/Image-aosp_nanopi3 directory to the android12 or androidtv directory in the FRIENDLYARM partition of the SD card: 

sudo cp -af parameter.txt config.cfg MiniLoaderAll.bin uboot.img \
    dtbo.img vbmeta.img boot.img recovery.img \
    misc.img pcba_small_misc.img pcba_whole_misc.img \
    baseparameter.img super.img /media/$USER/FriendlyARM/android12

3) Insert the SD card into {{{1}}} and re-flash;

2.5 Pack the new SD Image

git clone https://github.com/friendlyarm/sd-fuse_rk3588.git
SDFUSE=$PWD/sd-fuse_rk3588
mkdir $SDFUSE/android12
 
cd /path/to/rk35xx-android12/rockdev/Image-aosp_nanopi3
cp -af parameter.txt config.cfg MiniLoaderAll.bin uboot.img \
    dtbo.img vbmeta.img boot.img recovery.img \
    misc.img pcba_small_misc.img pcba_whole_misc.img \
    baseparameter.img super.img $SDFUSE/android12
 
cd $SDFUSE/
./mk-sd-image.sh android12
 
tar xvzf /path/to/netdrive/03_Partition\ image\ files/emmc-flasher-images.tgz
./mk-emmc-image.sh android12
