STM32MP257F-DK bare metal

[CrazyChel]

Hello!
Please tell me how to create a basic C/C++ BareMetal project in CubeIDE for the A35 core of the STM32MP257F-DK board?

When I create a project for STM32MP1 I have a choice to create a "BareMetal" project or a Linux project.
Unfortunately, when I create a project for STM32MP257F-DK, I did not find such an opportunity for the A35 core. Only a Linux project.

Considering that I need LVDS on the board, I cannot switch to the STM32MP1 series and the Linux boot time does not suit the customer.

My CubeIDE Version: 1.18.0
Build: 24413_20250227_1633 (UTC)

Hi @CrazyChel ,

ST does not have "Baremetal" offer yet on STM32MP2x platform. 

It's in our roadmap but only at evaluation stage. We will communicate as soon as we can.

Hi @Olivier GALLIEN ,

This thread is now more than one year old, so I would like to check whether there has been any update regarding Bare-Metal support on the STM32MP2x platform (specifically STM32MP257F-DK).

Is there now:

• An official Bare-Metal project template in CubeIDE?

• Any application notes or examples for running Cortex-A35 without Linux?

• Any roadmap update you can share?

Our use case requires:

• Fast boot time (Linux boot is not suitable)

• Direct control of LVDS/display pipeline

• A35 standalone execution without full Linux stack

If Bare-Metal is still not officially supported:

• What is the recommended approach from ST?

  • TF-A + custom BL33 payload?

  • Minimal U-Boot + ELF?

  • Any internal reference design?

Looking forward to your update.

Best regards,
