LINUX_SDK COMPILATION

SDK (Software Development Kit) is a collection of development tools provided for a specific software framework, hardware platform, or operating system, designed to help developers create applications more efficiently.

Compilation Host Configuration

Install Ubuntu on a PC to perform SDK compilation.

  • Hardware: PC must meet RAM ≥ 16 GB, CPU cores ≥ 4
  • Software: Ubuntu 18.04, allocate ≥ 100GB disk space for virtual machines

Note

Testing in ubuntu 22.04/20.04 environments results in numerous compilation errors; not recommended.
Compilation in WSL environment has not been tested and verified; not recommended.

Configuration and installation:

sudo apt install git bc bison build-essential curl flex libsdl1.2-dev 
sudo apt install g++-multilib gcc-multilib gnupg gperf libncurses5-dev 
sudo apt install imagemagick lib32ncurses5-dev lib32readline-dev squashfs-tools 
sudo apt install lib32z1-dev liblz4-tool xsltproc libssl-dev libwxgtk3.0-dev 
sudo apt install libxml2 libxml2-utils schedtool lzop pngcrush rsync 
sudo apt install yasm zip zlib1g-dev python device-tree-compiler 
sudo apt install python-pip gawk openjdk-8-jdk u-boot-tools patchelf expect
sudo pip install pyelftools

Obtaining SDK Source Code

Download SDK. Tina 5.0 Linux SDK supports building two filesystems: buildroot and ubuntu.

├── 1-SDK

│       ├── README.txt

│           ├── t113-linux-20251024.tar.gz
│           └── UPDATE_LOG.txt

Note

1.The SDK cannot be compiled in a shared directory.
2.The compilation host cannot log in using the ROOT account.

1. Copy the SDK source code archive to the compilation host directory and verify file integrity using MD5.

md5sum -c *.md5

2. Extract the source code archive.

tar -zxvf t113-linux-*.tar.gz

3. Restore the source code files.

cd t113-linux
ls -al
git reset --hard

Obtaining Rootfs Image

  • Download the Rootfs image. Typically, download the file with the latest date suffix.

  • Buildroot Rootfs

The provided buildroot-dl-*.tar.gz archive can be used for offline compilation of the Buildroot filesystem, reducing the time spent downloading source code during compilation.

Extract buildroot-dl-*.tar.gz into the buildroot/buildroot-201902 directory.

  • Ubuntu Rootfs

ubuntu-rootfs-*.tar.gz is the Ubuntu filesystem archive. Compiling it with the SDK source code can generate the Ubuntu system image.

Copy ubuntu-rootfs-*.tar.gz to the SDK's device/config/rootfs_tar directory and rename it to ubuntu-armhf.tar.gz.

Full Compilation

When executing build.sh for the first time to compile the SDK, you must select the compilation configuration and filesystem type.

  • SDK Compilation Configuration
./build.sh lunch
======you are building t113 linux======
1. BoardConfig-t113-s3-kickpi-k4b-buildroot.mk
2. BoardConfig-t113-s3-kickpi-k4b-ubuntu.mk
3. BoardConfig-t113-s3-kickpi-k4b-nand-buildroot.mk
4. BoardConfig-t113-s3-kickpi-k4b-nand-ubuntu.mk
which board would you like (1-4):            // Select based on board model and desired filesystem
  • Compile Image
./build.sh       \\ Compile
./build.sh pack  \\ Package to generate image

The generated system image is located at out/update-t113-s3-kickpi-k4b-xxxxxxx.img.

Individual Compilation

Compile U-Boot Individually

./build.sh uboot

Compile Kernel Individually

./build.sh kernel

Compile Buildroot Individually

./build.sh buildroot_rootfs

Other Commands

./build.sh menuconfig
./build.sh saveconfig

Buildroot Configuration

Tip

Configuration file path: buildroot/buildroot-201902/configs/sun8iw20p1_t113_defconfig
