Hi, Jeet14.

Thanks for comment.

As I know, some configuration needs for using Gadget Serial feature like below url.

Can I use the usb-gadget.cfg mentioned in this document as Agilex5 kernel configuration?

In device tree, the "dr_mode" property in usb node have to be added as I know.

This property can be configured as "peripheral", "otg", or "host".

Which value shoud I use?

Jung.
