1 Developer package : build AI application from the X-LINUX-AI add-on SDK
In order to easily develop and build an AI application without using the Yocto build system, X-LINUX-AI comes with a SDK add-on extending the OpenSTLinux SDK with AI functionality. To install and use the X-LINUX-AI SDK Add-on please refer to the following steps.
2.1 Install the OpenSTLinux SDK
First of all, you must download and install the OpenSTLinux SDK, which contains all the basis needed for the X-LINUX-AI add-on. To do this, follow instructions given in STM32MP1 Developer Package : Installing the SDK chapter. Once this has been done, you should have a directory containing the OpenSTLinux SDK.
3 X-LINUX-AI SDK add-on installation
3.1 Download the X-LINUX-AI SDK add-on
To add the Artificial Intelligence part into the OpenSTLinux SDK, you must download and install the X-LINUX-AI SDK add-on. The add-on is delivered through a tarball file that can be downloaded here: X-LINUX-AI SDK add-on.
3.2 Install the X-LINUX-AI SDK add-on
Once the X-LINUX-AI SDK add-on is downloaded, uncompress the add-on:
tar xzf en.SDK-x86_64-stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21-addon-x-linux-ai-v5.0.0.tar.gz
Then, copy the .sh script to your OpenSTLinux SDK directory:
cp stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21-addon-x-linux-ai-v5.0.0/st-image-ai-openstlinux-weston-stm32mp1-x86_64-toolchain-4.2.1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21-addon-x-linux-ai-v5.0.0.sh $HOME/STM32MPU_workspace/STM32MPU-Ecosystem-v5.0.0/Developer-Package/SDK
Finally, run the script contained in the tarball:
Optionally, once the script is executed, you can delete it.
3.3 Start the SDK
The add-on is now installed into the OpenSTLinux SDK. You can start the SDK. Go to your OpenSTLinux SDK directory and source the environment:
Check that the SDK is properly installed:
X-LINUX-AI version: v5.0.0
4 Use the SDK
4.1 Build an application with the SDK
Once the SDK is correctly set up, the applications can be built easily. In this example, it is the image classification application that is built.
Download the github repository:
Go to the image classification directory:
Then, use the make command to build the application:
A new file is displayed, named label_tfl_gst_gtk. This is a binary file, which has been generated using the make command. It is compiled for the STM32MP1x architecture. It must now be transferred to the board.
4.2 Use the application
Once the STM32MP1x board is correctly set up and the X-LINUX-AI packages are installed with the right version, it is possible to send the application to the board.
To do it, use the following command using your own IP address:
scp -r -p label_tfl_gst_gtk root@<ip_address>:/usr/local/demo-ai/computer-vision/tflite-image-classification/bin/
Then, use the ssh protocol to connect to the board:
On the board, go to the right directory and use the image classification script to launch the application:
cd /usr/local/demo-ai/computer-vision/tflite-image-classification/bin/ ./launch_bin_label_tfl_mobilenet.sh
This script is using the label_tfl_gst_gtk application that has been compiled before.
