It seems like CortexM55 would be first NN supporting via HW MCU and the MPS3 AN547 is the EVK with Zephyr supported.
But I cannot find the contact on getting the board for investigation or development, is there any way to purchase the HW? Or is there any misunderstanding I need to know about the platform of supporting NN with HW capability?
Here is the page for the MPS3 board, though it does seem that there is no availability of it currently:https://developer.arm.com/Tools%20and%20Software/MPS3%20FPGA%20Prototyping%20Board
Could you make use of the Fixed Virtual Platform (FVP), which is available (see Corstone-300):https://developer.arm.com/downloads/-/arm-ecosystem-fvps
It is also available as a component of Arm Virtual Hardware on AWS:https://www.arm.com/en/products/development-tools/simulation/virtual-hardware
Thanks for your information.
I will try to look into the virtual platform for development.
