How to boot Linux directly from UUU

[Ryo_Aoki]

Hi community.

I am currently using an i.MX6 SabreAI board.
I want to boot linux directly from serial downloader mode without writing to emmc or QSPI or SD card.
Is such usage possible?

I have already checked the following documents, but I do not understand the procedure.
whether it can be used in such a way
If possible, could you please tell me the command procedure?
