About  i.MX8M Mini's USB usage

I want to design a USB circuit using i.MX8M Mini.The circuit scheme is that USB2 as OTG, USB1 as slave, can you give me some design reference or suggestion.

I experimented on the development board, USB2 OTG can be used normally, but I can't use the USB1 OTG as a slave(USB1 OTG as a host is OK).

Additionally, after I disabled USB2 port,  USB1 OTG can be used normally. I don't know if USB1 can be used as a slave?

I am very troubled now, I hope to get your help as soon as possible.

Best wishes.
