Hello,

We need to use both usb host and usb device with am572x EVB.

I see in dwc3 wiki, that examples are for configuring both as host or both as client, so I am not sure if it's possible (to use one port as host and the other as client) .

in the wiki it is said

"AM57xx-evm use USB1 as Super-Speed host port and have a on-board Super-Speed hub which provides 3 Super-Speed Host (Type-A) ports. USB2 is used as High-Speed peripheral port. VBUS detection for USB2 port is provided through Power Management IC (palmas). " , so the assumption is that both should work at the same time, Right ?

Best Regards,

Hello Biser,

Thank you for the link. I understand the description.
Yet,
Does it mean that both ports can operate together ,at the same time, (so that one is host and the other is peripheral) ?

Regards,
Ran

Ran,

Yes, both configurations can operate at the same time. This is how all current AM57x EVMs (GP-EVM, IDK, ...) are configured, one USB module is in host-only mode, another is in peripheral-only or dual-role mode.
