6.1.6 Booting from SD on the i.MX 7Dual SABRE-SD board

It is written as follows.

Download mode (MFGTool mode)	SW4: 00100000 (from 1-8 bit) Boot_Mode: 01 (from 1-2 bit)
SD boot	SW4: 00111000 (from 1-8 bit) Boot_Mode: 10 (from 1-2 bit)

To boot from SD, perform the following operations:
Chang the board Boot_Mode switch to 10 (from 1-2 bit) and SW4 00100000 (from 1-8 bit).

I think that SW4: 00111000 (from 1-8 bit) is the correct answer.

Which is the correct answer?
