STM32L5 has Cortex-M33 processor. In the official documentation it says that Cube.AI supports Cortex-M CPUs (including M33). Why is it still not possible to choose AI library for Cortex-M33 on STMCubeMX IDE? Is there anything fundamentally different that there is no support?
When selecting a MCU or board STM32L5 (Cortex M33) please don't activate the trustzone. You will be then able to select Cube.AI and generate project with the Cortex M33 AI library. The multi-context is not yet enabled in Cube MX, but the generated library will run whatever the context (trustzone or not), you just need to deactivate the trustzone in Cube MX to enable Cube.AI.
