Does stm32mp157-dk1 support traditional SPL boot uboot?

[Tuzki]

HI.

Recently I purchased a stm32mp157-dk1. I am going to learn to use uboot. I know that Uboot startup is divided into several parts. The second part is SPL, and then SPL will boot uboot, and uboot will continue to boot the Linux kernel.

I have read the STM32MP157 documentation and it says that STM32MP157 does not support SPL. Is this true? Is the SPL boot option never available or is it optional?

Hi @Tuzki 

 

as you can see on this page, OpenSTLinux is not compatible with U-boot SPL.
You can use it, but it cannot be used for product development :

HI @Tuzki 

I confirm SPL is not supported.
