how to boot OpenSTlinux for the Stm32MP157 from ram ?

[iheb]

Hello

Newbie question here, so i was working for with the stm32mp157 for quite a while now .the boot process for me was flashing an SD Card or a USB stick and boot the thing up.

How ever i was wondering if there is a method to load openstlinux or just u-boot into RAM and Un-mount the disk or something and the Linux will keep working like with Ubuntu (Boot to Ram) ?

if so how to do it ?

Thank you

I can understand the concept on a minimal linux system setting if initially tailored for such use.

But not on our OpenSTLinux delivery, u-boot needs a mount partition from an NVM storage (SDcard, NAND flash, emmc) that is not unmounted afterwards.

I recommend you to read our wiki articles on the subject:
