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.

Build Environment Setup

Install Ubuntu on a PC for SDK compilation.

  • Hardware: PC with RAM ≥ 16 GB, CPU cores ≥ 4, Hard Drive ≥ 500GB
  • Software: Ubuntu, VM disk space ≥ 200GB

Install dependencies:

Tip

If dependency installation errors occur, check the error messages and install the corresponding packages.

Obtain SDK Source Code

Note

  1. Do not place the SDK in a shared directory for compilation.
    1. Do not compile while logged in as the ROOT user.

1. Click to download Linux SDK source, click to download release_sdk.sh. Download the latest files based on the date suffix.

2. Place the tar.gz package, md5sum file, and release_sdk.sh script in the same directory on the build host.

t527-linux-*.tar.gz
t527-linux-*.md5sum
release_sdk.sh

3. Run the script to extract the SDK source.

chmod +x ./release_sdk.sh
./release_sdk.sh

Diagram: "All files processed successfully!" indicates the script ran successfully.

Full Compilation

Tip

The T527 Linux SDK currently only maintains Debian 11.

1. Navigate to the SDK root directory and run the following command to configure the build target.

./build.sh lunch

Select the configuration file. This determines which DTS file is used. Select the second option.

./build.sh lunch

You're building on Linux
Lunch menu...pick a combo:

1. BoardConfig-t527-default.mk
2. BoardConfig-t527-kickpi-k9.mk

2. Configure the build environment

./build.sh config

Make selections according to the configuration below:

./build.sh config
