You should take care the followings.
Would you refer it ?
1) Modify some code for peripheral IC at FSBL.
=> It depends on your environment.
2) Use booting sequence and code at u-boot.
=> You need to re-configure and/or re-build u-boot from source code to support USB booting. It depends on version and configuration of u-boot.

Sorry, maybe I didn't say it clearly. I see UG1209 usb startup steps. But starting up requires that you use a computer as the host to download the image. I would like to ask is USB boot can support boot from the U disk?

The only way to boot from USB (as a primary boot device) in MPSoC is using the DFU protocol to communicate with an attached host.
