1. Re-generate X-LINUX-AI OpenSTLinux distribution[edit | edit source]
With the following procedure, you can re-generate the complete distribution enabling the X-LINUX-AI expansion package.
This procedure is mandatory if you want to update frameworks by yourself, or generate your own X-LINUX-AI distribution by selecting the relevant AI framework for your applications.
1.1. Download the Distribution Package[edit | edit source]
- Install the OpenSTLinux Distribution Package by following the dedicated article : STM32MPU Distribution Package, but do not initialize the OpenEmbedded environment (do not source the envsetup.sh).
1.2. Install X-LINUX-AI environment[edit | edit source]
- Clone the meta-st-x-linux-ai git repositories
For X-LINUX-AI v6.0.1: cd <Distribution Package installation directory>/layers/meta-st git clone https://github.com/STMicroelectronics/meta-st-x-linux-ai.git -b v6.0.1
- For a new environment
Source the build environment with the correct board and layer:
cd ../.. DISTRO=openstlinux-weston MACHINE=<machine> BSP_DEPENDENCY='layers/meta-st/meta-st-x-linux-ai' source layers/meta-st/scripts/envsetup.sh
Note that:
- Possible values for DISTRO, MACHINE and IMAGE are proposed in OpenSTLinux distribution
- For an already installed environment
Add the meta-st-x-linux-ai to Yocto environment:
cd ../.. source layers/meta-st/scripts/envsetup.sh bitbake-layers add-layer ../layers/meta-st/meta-st-x-linux-ai/
1.3. Build the image[edit | edit source]
- For STM32MP2x with AI hardware accelerator
bitbake st-image-ai-npu
 Information
|
| Note that building the image could take long time depending on the host computer performance. |
- For STM32MPU without AI hardware accelerator
bitbake st-image-ai-cpu
| Information
|
| Note that building the image could take long time depending on the host computer performance. |
1.4. Flash the built image[edit | edit source]
