1. Article purpose[edit source]
This article describes how to install and use the X-LINUX-AI SDK add-on.
2. Prerequisites[edit source]
2.1. Install the OpenSTLinux SDK[edit source]
First of all, you need to download and install the OpenSTLinux SDK which contains all the basis needed for the X-LINUX-AI add-on. To do this, follow the first four sections of the OpenSTLinux SDK tutorial. Once this has been done, you should have a directory containing the OpenSTLinux SDK.
3. X-LINUX-AI SDK add-on Installation[edit source]
3.1. Download the X-LINUX-AI SDK add-on[edit source]
To add the Artificial Intelligence part into the OpenSTLinux SDK, you need to download and install the X-LINUX-AI SDK add-on. The add-on are delivered through a tarball file named : SDK-X-LINUX-AI-addon.tar.gz and can be downloaded here: X-LINUX-AI SDK add-on.
3.2. Install the X-LINUX-AI SDK add-on[edit source]
3.2.1. For STM32MP15x lines[edit source]
After that, you need to uncompress the tarball file in your OpenSTLinux SDK directory. First, copy the add-on to the OpenSTLinux SDK directory:
cp ~/Downloads/SDK-X-LINUX-AI-addon.tar.gz $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v4.0.0/Developer-Package/SDK
Then, move to you OpenSTLinux SDK directory:
cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v4.0.0/Developer-Package/SDK
Finally, uncompress the tarball:
tar xzf SDK-X-LINUX-AI-addon.tar.gz
3.2.2. For STM32MP13x lines[edit source]
After that, you need to uncompress the tarball file in your OpenSTLinux SDK directory. First, copy the add-on to the OpenSTLinux SDK directory:
cp ~/Downloads/SDK-X-LINUX-AI-addon.tar.gz $HOME/STM32MPU_workspace/STM32MP13-Ecosystem-v4.0.0/Developer-Package/SDK
Then, move to you OpenSTLinux SDK directory:
cd $HOME/STM32MPU_workspace/STM32MP13-Ecosystem-v4.0.0/Developer-Package/SDK
Finally, uncompress the tarball:
tar xzf SDK-X-LINUX-AI-addon.tar.gz
3.3. Start the SDK[edit source]
3.3.1. For STM32MP15x lines[edit source]
The add-on are now installed into the OpenSTLinux SDK, you can start the SDK as it is described in the OpenSTLinux SDK installation process. Go to your OpenSTLinux SDK directory and source the environment:
cd $HOME/STM32MPU_workspace/STM32MP15-Ecosystem-v4.0.0/Developer-Package/SDK
source environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
3.3.2. For STM32MP13x lines[edit source]
The add-on are now installed into the OpenSTLinux SDK, you can start the SDK as it is described in the OpenSTLinux SDK installation process. Go to your OpenSTLinux SDK directory and source the environment:
cd $HOME/STM32MPU_workspace/STM32MP13-Ecosystem-v4.0.0/Developer-Package/SDK
source environment-setup-cortexa7t2hf-neon-vfpv4-ostl-linux-gnueabi
4. Use the SDK[edit source]
4.1. Build an application with the SDK[edit source]
Once the SDK is correctly setup, the applications can be built easily. At first choose the application, in this example the image classification application will be built. Go to the image classification directory:
cd openstlinux-4.0/layers/meta-st/meta-st-stm32mpu-ai/recipes-samples/tflite-cv-apps/files/image-classification/
