STM32MP257F-DK: M33 Master / Cold boot

SquishyHeart · ‎2025-09-07

Hi,

I saw this post on the forum about 'M33 cold boot' and the possible release of the ecosystem to do so :

https://community.st.com/t5/stm32-mpus-products-and-hardware/using-only-the-m33-on-the-stm32mp2-feasibility-and-peripheral/td-p/768536

Is there any update about it ?

If released, will it be possible for the M33 to launch the boot process of the Cortex-A and maybe power it off depending on the context ?

Thanks.

Regards.
