Media boot

Hy Ladies and Gentlemen ^^.
For a Project, sometime i would need to boot on sd and sometime on emmc (or M2 i will see).
Can we do it ?
Something to modify in the u-boot?

Thanks by advance.

This is a feature of u-boot’s distro boot configuration. Please refer to u-boot’s documentation on booting individual devices, u-boot/README.distro at master · ARM-software/u-boot · GitHub

Thanks you to answer me ^^
I will work on the u-boot
