4. Compile Android10.0

4.1. Download Android SDK

Due to the larger SDK, you can choose the cloud disk to download Firefly-RK3399_Android10.0_git_20211222.7z from the download page :

Download link

Note: the source code and bundle are stored in the Google Driver

After downloading, verify the MD5 code:

$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.001
$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.002
$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.003
$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.004
$ md5sum /path/to/Firefly-RK3399_Android10.0_git_20211222.7z.005

9b1656ae07b4fe9ddf7d9ef2dfa2f95a  Firefly-RK3399_Android10.0_git_20211222.7z.005

After confirming that it is correct, you can unzip:

cd ~/proj/
7z x ./Firefly-RK3399_Android10.0_git_20211222.7z.001 -ork3399_Android10.0
cd ./rk3399_Android10.0
git reset --hard

Note: Be sure to update the remote warehouse after decompression. The following is how to update from gitlab:

1. Enter the SDK root directory
cd ~/proj/rk3399_Android10.0

2. Download remote bundle repository
git clone https://gitlab.com/TeeFirefly/rk3399-android10.0-bundle.git .bundle

3. If the download warehouse fails, the current bundle warehouse is about 1.4G, so there may be stuck or failed problems during synchronization. You can download and unzip it from the cloud disk link below to the SDK root directory.

7z x rk3399-android10.0-bundle.7z  -r -o. && mv rk3399-android10.0-bundle/ .bundle/

4. Update the SDK, and subsequent updates do not need to pull the remote warehouse again, just execute the following command
.bundle/update

5. Follow the prompts to update the content to FETCH_HEAD, synchronize FETCH_HEAD to the firefly branch
git rebase FETCH_HEAD

4.2. ROC-RK3399-PC-PLUS product compilation method

4.2.1. Overall Compilation

Note: Since the the Hardware iteration version of ROC-RK3399-PC-PLUS is ROC-RK3399-PC Pro, so the compilation method of software is consistent. Finally the generated firmware, such as ROC-RK3399-PC-Pro_xxx.img is compatible with ROC-RK3399-PC-PLUS.

4.2.1.1. Public Compile

4.2.1.1.1. HDMI+DP
./FFTools/make.sh -d rk3399-roc-pc-plus -j8 -l rk3399_roc_pc_plus-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3399_roc_pc_plus-userdebug

4.2.1.2. Display DM-M10R800 V2 Compile

4.2.1.2.1. MIPI_DSI0+HDMI

./FFTools/mkupdate/mkupdate.sh -l rk3399_roc_pc_plus_mipi-userdebug

4.2.1.3. Camera OV13850 Compile

4.2.1.3.1. HDMI+OV13850

  • Modify kernel/arch/arm64/boot/dts/rockchip/rk3399-roc-pc-plus.dtsi

 &i2c1{

-    XC6130b@23{
+    ov13850b@10{
     status = "okay";
     };
-    XC7022b@1b{
+    ov13850f@10{
     status = "okay";
     };

-    /delete-node/ ov13850b@10;
-    /delete-node/ ov13850f@10;
+    /delete-node/ XC6130b@23;
+    /delete-node/ XC7022b@1b;

 };

  • Compile

./FFTools/make.sh -d rk3399-roc-pc-plus -j8 -l rk3399_roc_pc_plus-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3399_roc_pc_plus-userdebug

4.2.1.4. Dual Camera SV-TAYSH-TQ Compile

4.2.1.4.1. HDMI+SV-TAYSH-TQ

  • Modify kernel/arch/arm64/boot/dts/rockchip/rk3399-roc-pc-plus.dtsi

    xc7160b@1b{
+    status = "disabled";
    };
    xc7160f@1b{
+    status = "disabled";
    };

    XC6130b@23{
+    status = "okay";
    };
    XC7022b@1b{
+    status = "okay";
    };

  • Compile

./FFTools/make.sh -d rk3399-roc-pc-plus -j8 -l rk3399_roc_pc_plus-userdebug
./FFTools/mkupdate/mkupdate.sh -l rk3399_roc_pc_plus-userdebug

4.2.2. Step by Step Compilation

Before compiling, execute the following command to configure environment variables:

source ./FFTools/build.sh

  • Compile kernel:

cd ~/proj/rk3399_Android10.0/kernel/
make ARCH=arm64 firefly_defconfig android-10.config rk3399.config
make ARCH=arm64 BOOT_IMG=../rockdev/Image-rk3399_roc_pc_plus/boot.img rk3399-roc-pc-plus.img -j8

  • Note：If you going to do kernel debug，you need pack the resource.img and kernel.img together into boot.img,then upgrade the boot,img into boot partition.

  • Compile uboot：

cd ~/proj/rk3399_Android10.0/u-boot/
./make.sh rk3399

  • Compile Android：

cd ~/proj/rk3399_Android10.0/
lunch rk3399_roc_pc_plus-userdebug
make -j8
./mkimage.sh

  • Packaged into unified firmware

After compilation, you can use Firefly official scripts to package into unified firmware, execute the following command：

./FFTools/mkupdate/mkupdate.sh -l rk3399_roc_pc_plus-userdebug

According to different -l XXX-userdebug parameters, the packaged unified firmware will be stored in different directories (rockdev/image-XXX/): product name XXX_XXX_date XXX.img

It is also very simple to package the unified firmware update.img under Windows. Copy the generated files to the rockdev \ Image directory of AndroidTool, and then run the mkupdate.bat batch file under the rockdev directory to create update.img and store it in rockdev \ Image directory.
