U-Boot

[Shakhrukh Shakirov]

Hi guys,

I need consultation regarding U-BOOT, how to realize following on Raspberry pi 5:
We have 1 SD card which stores: U-BOOT, OS1, OS2, OS config
So UBOOT starts OS1 with OS config.
>From OS1 I can upgrade OS2, and change boot orders (so it will run not OS1, instead will run OS2 with OS config).
>From OS2 I can update firmware of OS1.
In case of failure of OS1 or OS2, it will run other OS version.
With who can I consult and what would be the rate?

Thanks  in advance.
