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.

one more clarification is, if the USB_OTG_OC not connected and left it floating, work for USB host only application?

Hi @JACOBTHOMAS_007 ,

 

Thanks for your reply.

Yes, you can left USB_OTG_OC  pin floating,  and you can also leave this pin uninitialized in the code.

Thanks for the reply,

From the EVK design files I see it uses a CC logic IC PTN5150A, but if I want the MIMXRT1046XFQ5B to only behave as host can I exclude using this IC? and then by default does the MCU MIMXRT1046XFQ5B USB Mode is HOST?

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.
