I just started learning about U-Boot and being able to write applications that can be run with U-Boot, so please be patient and if possible add more details to help me learn.

I wanted to ask for help, as I am trying to connect USB flash drive to my Arm Cortex A9 device, which then connects to my laptop via Ethernet. I want to be able to have access to all files on that drive through my U-Boot script. For example My script will just run after U-Boot loads, and my script will parse through all files. Then I'd like to be able to access the files from my host laptop through TFTP commands, but feel will need to write functions that translate TFTP request to a USB read?

I plan to use a U-Boot application, so that I have access to all U-Boot drivers. U-boot supports USB, and I am able to see my USB Flash Drive on the U-boot command line. How can this be done, any help is HIGHLY appreciated please.
