IMRT1046 USB Host connection

[JACOBTHOMAS_007]

I couldn't find the USB_OTG1_ID pin in MIMXRT1046XFQ5B processor, does that means by default the USB controller behaves as HOST? We are using this processor to build a custom USB host to get data from other USB devices.

Thanks for the reply, and the design files

The EVK design uses a USB type-C CC logic IC. But My question is what if I don't want to use this CC logic IC, does by default the MIMXRT1046XFQ5B behaves as HOST? In case I only bring out the 4 USB OTG pins out to a USB A connector and connect a USB device/client to this connector?

Hi @JACOBTHOMAS_007 ,

Thanks for your reply.

Yes, You can choose not to use USB type-C CC logic IC.

When the RT1046 is required to operate only as a USB Host, a direct implementation with a Type-A receptacle is sufficient. 

In software, Please explicitly configure the USB role as Host mode.

Please ensure the RT1046 board provides stable VBUS power to the USB port.

Hi @JACOBTHOMAS_007 ,

Thank you so much for your interest in our products and for using our community.

Yes, There is no USB_OTG1_ID pin in MIMXRT1046XFQ5B processor USB peripheral , However, you can use other Chip IO to realize the function.

The USB in MIMXRT1046XFQ5B processor still support Host or Device mode.

I suggest you can refer to MIMXRT1046-EVK design.
