Can anyone share how to manually mount and unmount USB storage device in U-boot?

I need to program the u-boot to search for a file in the USB.
The USB will be having fat file system.
I want to search for a image and load the image and then execute it. Its a small firmware/executable.

Thanks.

Answer 1

You can't.

U-boot doesn't really have a concept of mounting filesystems, so it also can't unmount them.
