STM32MP257F-DK bare metal

[Sivakumar_Mulugu]

Hello,

I would like to ask about the current status of Bare-Metal support for the Cortex-A35 core on the STM32MP2x platform (STM32MP257F-DK).

While searching the ST Community, I came across the following discussion related to this topic:

https://community.st.com/t5/stm32-mpus-embedded-software-and/stm32mp257f-dk-bare-metal/td-p/787100

Since that discussion is now more than one year old, I wanted to check whether there have been any updates regarding Bare-Metal development support on the STM32MP2 platform.

When creating a project in STM32CubeIDE for the STM32MP257F-DK, I could not find an option to create a Bare-Metal project targeting the Cortex-A35 core.

Could you please clarify the following:

• Is there now an official Bare-Metal project template for Cortex-A35 in STM32CubeIDE?

• Are there any application notes, examples, or documentation demonstrating how to run Cortex-A35 without Linux?

• Is there any roadmap update regarding official Bare-Metal support for STM32MP2x?

Our use case requires:

• Fast boot time (Linux boot time is not suitable for our application)

• Direct control of the LVDS/display pipeline

• Standalone execution on Cortex-A35 without a full Linux stack

If Bare-Metal execution on A35 is still not officially supported, could you please advise on the recommended approach from ST?

For example:

• Using Trusted Firmware-A (TF-A) with a custom BL33 payload

• Using minimal U-Boot to load and execute an ELF

• Any internal reference design or recommended architecture

Any guidance or reference material would be greatly appreciated.

Best regards,
Siva Kumar Mulugu

Hi @Sivakumar_Mulugu ,

We have launch the support of Baremetal and we are in Alpha phase

If you are interesting to be involved please contact your local ST support.

Hi @Olivier GALLIEN ,

Thank you for your response.

It is great to hear that Bare-Metal support for Cortex-A35 is now available in the Alpha phase. I am very interested in being involved.

Our current use case requires fast boot time, direct control of the display pipeline (LVDS), and standalone execution on Cortex-A35 without a full Linux stack. Hence, this support is highly relevant to us.

Could you please guide me on how to proceed with local ST support or share the appropriate contact/channel to get access to this Alpha program?

Looking forward to your guidance.

Best regards,
Sivakumar
