NS1081S_U disk_BGA153/221/254

Overview

It cannot be tested temporarily or there are design problems. This design is for reference only.
I used two pieces of emmc for testing. Both of them can update the firmware, but the formatting error occurs. The emmc is good. There is no problem in reading the files in the dg software, but it cannot be written.

Updated on 2022/08/09, debugging passed, usb3.0 cannot be used, and it can be used by leaving the rst of emmc unconnected. .
Now the usb3.0 cannot be recognized when plugged in. I don’t know why
the speed test U2 has no problem at full speed.
A 4g chip is used here.
