2. Software Preparation

SDK Overview

Tina5.0 Linux SDK supports two filesystems: Buildroot and Ubuntu.

Obtain SDK Source Code

Download SDK from Cloud Storage Cloud storage directory:

1-SDK/linux/sdk/xxxxxxx/  
    t113-linux-*.tar.gz  
    t113-linux-*.md5  

Copy SDK to Build Host

Important: Do not place the SDK in shared folders if using a VM.

Verify File Integrity

$ md5sum -c *.md5  

Extract SDK

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

Warning: Do NOT use root privileges! The SDK contains Git repositories (check .git with ls -al).

Initialize Source Code

$ cd t113-linux  
$ git reset --hard  

Warning: Do NOT use root privileges!

Obtain Rootfs Images

Filesystem Directory in Cloud Storage:

1-SDK/linux/rootfs/  
    buildroot-dl-*.tar.gz  
    ubuntu-rootfs-*.tar.gz  

• Buildroot Filesystem Extract buildroot-dl-*.tar.gz to buildroot/buildroot-201902/.

• Ubuntu Filesystem Copy ubuntu-rootfs-*.tar.gz to device/config/rootfs_tar/ and rename it to ubuntu-armhf.tar.gz.
