=====FriendlyWrt 23.05=====
 +
<syntaxhighlight lang="bash">
 +
mkdir friendlywrt23-rk3399
 +
cd friendlywrt23-rk3399
 +
git clone https://github.com/friendlyarm/repo --depth 1 tools

 +
tools/repo sync -c  --no-clone-bundle
 +
</syntaxhighlight>
 +
====First compilation step====
 +
<syntaxhighlight lang="bash">
 +
./build.sh rk3399.mk  # or rk3399-docker.mk
 +
</syntaxhighlight>
 +
All the components (including u-boot, kernel, and friendlywrt) are compiled and the sd card image will be generated, then execute the following command to generate the image file for installing the system into the emmc:
 +
<syntaxhighlight lang="bash">
 +
./build.sh emmc-img
 +
</syntaxhighlight>
 +
After making changes to the project, the sd card image needs to be repackaged by running the following command:
 +
<syntaxhighlight lang="bash">
 +
./build.sh sd-img
 +
</syntaxhighlight>
 +
====Secondary compilation steps====
 +
<syntaxhighlight lang="bash">
 +
cd friendlywrt
 +
make menuconfig
 +
rm -rf ./tmp
 +
make -j${nproc}
 +
cd ../
 +
./build.sh sd-img
 +
./build.sh emmc-img
 +
</syntaxhighlight>
 +
====Build u-boot only====
 +
<syntaxhighlight lang="bash">
 +
./build.sh uboot
 +
</syntaxhighlight>
 +
====Build kernel only====
 +
<syntaxhighlight lang="bash">
 +
./build.sh kernel
 +
</syntaxhighlight>
 +
====Build friendlywrt only====
 +
<syntaxhighlight lang="bash">
 +
./build.sh friendlywrt
 +
</syntaxhighlight>
 +
Or go to the friendlywrt directory and follow the standard openwrt commands. If you get an error with the above command, try using the following command to compile in a single thread:
 +
<syntaxhighlight lang="bash">
 +
cd friendlywrt
 +
make -j1 V=s
 
</syntaxhighlight>

The MBR partitioning is only used by the Linux v4.4 kernel. You can check the partition layout by clicking on this link: [https://github.com/friendlyarm/sd-fuse_rk3399/blob/master/prebuilt/parameter.template partmap]. To write an image file, you can use the dd command. For example, in the parameter.template file, "0x00014000@0x00014000(kernel)" specifies that the kernel partition starts at 0x00014000, which is equivalent to 81920 in decimal. Therefore, the dd command should be as follows:

The OS uses GPT partitions by default which is using the Linux v4.19 and Linux v5.15 kernel, you can use the dd command, but be careful to choose the right output device:
 +
* The SD/TF Card device node: /dev/mmcblk0 <br />
 +
* The eMMC device node: /dev/mmcblk2 <br />
 +
The following is an example of how to update the kernel to eMMC:<br />
 +
Use the 'parted' command to view the partition layout:
 
<syntaxhighlight lang="bash">
 
<syntaxhighlight lang="bash">
−
git clone https://gitlab.com/friendlyelec/rk3399-nougat.git
+
parted /dev/mmcblk2 print
 
</syntaxhighlight>
 
</syntaxhighlight>
 +
Sample outputs:
 +
<syntaxhighlight lang="bash">

 +
=====Packaging and creating an SD image=====
 +
To create a new OS image file, you need to use the "sd-fuse" packaging tool.<br />
 +
<br />
 +
"sd-fuse" is a collection of scripts that can be used to create bootable SD card images for FriendlyElec boards. Its main features include:<br />
 +
* Creation of root filesystem images from a directory <br />
 +
* Building of bootable SD card images<br />
 +
* Simple compilation of kernel, U-Boot, and third-party drivers<br />

* Your computer should have at least 16GB of RAM and 300GB of disk space. We recommend using a machine with 32GB of RAM and a large-capacity, high-speed SSD, and we do not recommend using virtual machines.
 +
* If you encounter compilation errors, they may be caused by problems with the compilation environment. We recommend using the following Docker container for compilation: [https://github.com/friendlyarm/docker-cross-compiler-novnc docker-cross-compiler-novnc].
 +
 
 +
====Compile Android10====
 +
=====Download Android10 Source Code=====
 +
There are two ways to download the source code:
 +
* '''repo archive file on netdisk'''
 +
Netdisk URL: [http://download.friendlyelec.com/{{#replace:{{#replace:{{BASEPAGENAME}}| |}}|/zh|}} Click here]<br />
 +
File location on netdisk："07_Source codes/rk3399-android-10.git-YYYYMMDD.tar.xz" (YYYYMMDD means the date of packaging)<br />
 +
After extracting the repo package from the network disk, you need to execute the sync.sh script, which will pull the latest code from gitlab:
 +
<syntaxhighlight lang="bash">
 +
tar xf "/path/to/netdisk/07_Source codes/rk3399-android-10.git-YYYYMMDD.tar.xz"
 +
cd rk3399-android-10
 +
./sync.sh
 +
</syntaxhighlight>
 +
* '''git clone from gitlab'''
 +
{{{1}}} source code is maintained in gitlab, You can download it by running the following command:
 +
<syntaxhighlight lang="bash">
 +
git clone --recursive https://gitlab.com/friendlyelec/rk3399-android-10.git -b main
 +
</syntaxhighlight>
 +
Note: If the following error "error: unknown option `recurse-submodules'" appears, please upgrade git to v2.0.0 or above.
 +
=====Generate Image File=====
 +
You can compile an Android source code and generate an image file (non-root user is recommended):
 +
<syntaxhighlight lang="bash">
 +
cd rk3399-android-10
 
./build-nanopc-t4.sh -F -M
 
./build-nanopc-t4.sh -F -M
 
</syntaxhighlight>
 
</syntaxhighlight>
 +
If you need to include google apps, you need to set an environment variable and then compile, as shown below:
 +
<syntaxhighlight lang="bash">
 +
cd rk3399-android-10
 +
export INSTALL_GAPPS_FOR_TESTING=yes
 +
./build-nanopc-t4.sh -F -M
 +
</syntaxhighlight>
 +
 +
=====Make OTA Packages=====
 +
If you need the support of A/B (Seamless) System Updates, you need to do the following:<br />
 +
a) Build your own update server for http download of update files;<br />
 +
b) Customize the Updater application, the code is located in packages/apps/Updater, let it connect and download file from your server;<br />
 +
c) Use the quick compilation script parameter -O or --ota to compile OTA Packages, as shown below:
 +
<syntaxhighlight lang="bash">
 +
cd rk3399-android-10
 +
./build-nanopc-t4.sh -F -O -M
 +
</syntaxhighlight>
 +
After the compilation is successfully completed, the OTA update related packages are located in the directory: rockdev/otapackage/ ，Please do not delete this directory.<br />
 +
After you have made some changes, compiling again with the parameter -O will generate ota-update-XXXXXXXX.zip, which is an incremental update package.<br />
 +
OTA Packages decides whether to generate incremental update package according to BUILD_NUMBER, for details, please refer to build-nanopc-t4.sh.<br />
 +
To disable the A/B feature, you can refer to the following to modify device/rockchip/rk3399/nanopc-t4/BoardConfig.mk, and then recompile uboot and android:<br />
 +
<syntaxhighlight lang="bash">

mkdir friendlywrt21-rk3399
cd friendlywrt21-rk3399
git clone https://github.com/friendlyarm/repo --depth 1 tools
tools/repo init -u https://github.com/friendlyarm/friendlywrt_manifests -b master-v21.02 \
        -m rk3399.xml --repo-url=https://github.com/friendlyarm/repo  --no-clone-bundle
tools/repo sync -c  --no-clone-bundle
1.1.2 FriendlyWrt 23.05
mkdir friendlywrt23-rk3399
cd friendlywrt23-rk3399
git clone https://github.com/friendlyarm/repo --depth 1 tools
tools/repo init -u https://github.com/friendlyarm/friendlywrt_manifests -b master-v23.05 \
        -m rk3399.xml --repo-url=https://github.com/friendlyarm/repo  --no-clone-bundle
tools/repo sync -c  --no-clone-bundle

1.2 First compilation step

./build.sh rk3399.mk  # or rk3399-docker.mk

All the components (including u-boot, kernel, and friendlywrt) are compiled and the sd card image will be generated, then execute the following command to generate the image file for installing the system into the emmc: 

./build.sh emmc-img

After making changes to the project, the sd card image needs to be repackaged by running the following command: 

./build.sh sd-img

1.3 Secondary compilation steps

cd friendlywrt
make menuconfig
rm -rf ./tmp
make -j${nproc}
cd ../
./build.sh sd-img
./build.sh emmc-img

1.4 Build u-boot only

./build.sh uboot

1.5 Build kernel only

./build.sh kernel

1.6 Build friendlywrt only

./build.sh friendlywrt

Or go to the friendlywrt directory and follow the standard openwrt commands. If you get an error with the above command, try using the following command to compile in a single thread: 

cd friendlywrt
make -j1 V=s

3.7 Running the build

3.7.1 Install to target board
3.7.1.1 MBR partition

This section applies to the following operating systems:

lubuntu eflasher friendlydesktop-arm64 friendlycore-arm64

The MBR partitioning is only used by the Linux v4.4 kernel. You can check the partition layout by clicking on this link: partmap. To write an image file, you can use the dd command. For example, in the parameter.template file, "0x00014000@0x00014000(kernel)" specifies that the kernel partition starts at 0x00014000, which is equivalent to 81920 in decimal. Therefore, the dd command should be as follows: 

dd if=kernel.img of=/dev/mmcblk0 seek=81920
3.7.1.2 GPT partition

This section applies to the following operating systems:

ubuntu-focal-desktop-arm64 debian-bookworm-core-arm64 debian-bullseye-desktop-arm64 debian-bullseye-minimal-arm64
friendlycore-focal-arm64 ubuntu-noble-core-arm64 friendlywrt21-kernel4 buildroot
friendlywrt21 friendlywrt21-docker friendlywrt23 friendlywrt23-docker

The OS uses GPT partitions by default which is using the Linux v4.19 and Linux v5.15 kernel, 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

The following is an example of how to update the kernel to eMMC:
Use the 'parted' command to view the partition layout: 

parted /dev/mmcblk2 print

Sample outputs: 

Model: MMC BJTD4R (sd/mmc)
Disk /dev/mmcblk2: 31.3GB
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               trust
 3      16.8MB  21.0MB  4194kB               misc
 4      21.0MB  25.2MB  4194kB               dtbo
 5      25.2MB  41.9MB  16.8MB               resource
 6      41.9MB  83.9MB  41.9MB               kernel
 7      83.9MB  134MB   50.3MB               boot
 8      134MB   2500MB  2366MB  ext4         rootfs
 9      2500MB  31.3GB  28.8GB  ext4         userdata

as shown above, the resource partition is located at 5 and the kernel partition is located at 6. 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/mmcblk2p5 bs=1M
dd if=kernel.img of=/dev/mmcblk2p6 bs=1M

If you want to update u-boot: 

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

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

3.7.2 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 v4.4.y sd-fuse
linux v4.19.y
sd-fuse_rk3399/kernel-4.19
linux v6.1.y
sd-fuse_rk3399/kernel-6.1.y
3.7.3 USB flashing

Note: kernel v4.4.y is not supported

3.7.3.1 Linux

Reboot the board and enter loader mode with the following command: 

sudo reboot loader

To flash U-Boot and kernel using the "upgrade_tool_v2.17_for_linux" tool, please use the following command: 

sudo upgrade_tool di -k kernel.img
sudo upgrade_tool di -re resource.img
sudo upgrade_tool di -u uboot.img
sudo upgrade_tool RD

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