Error booting from EMMC

[KMcev.1]

When trying to boot from emmc I get the following error ...

�NOTICE:  CPU: STM32MP157DAB Rev.Z

I assume this is an error with my tf-a bootloader? 

I compiled tf-a with the build flag STM32MP_EMMC=1. Are there any other modifications/variables to set when building the tf-a to enable it to boot from emmc?

Hi @KMcev.1 ,

can you please specify model and provider of STM32MP157DAB-INSTRUO-SOM ? 

Usually SOM maker have to do the support for their module 

Thanks
