Not an error,  you're in the bootloader - u-boot.
You need to boot past that into the OS.

I'm pretty new about that module. I don't know how I do. Can you help me if you know something?

Also I want to use this module for image processing. There are some OS in that. How can I change some files in it? I wanna do some image processing with it. I need to do modification and add some code to OS. Can I do that?

Suggest read the uBoot docs for what is (possibly) available.

a uboot is a preboot that loads the OS
You will need to see if you have an OS on your board to boot into.

I'd try some common commands like

and try see what partitions you have etc
