If you can do that then that's perfect because my English is always not very good. So that means I sometimes need more review on my English sentences.

Thanks for the clarification.

I can work on creating a README file for this board after I manage to boot it.

What is the process of flashing the flash.bin and u-boot.itb binaries
to the eMMC?

Do you use the uuu tool? If so, what is the  uuu_script script that you use?

Thanks,
