I apologize if this has been answered. It so, I cannot find it. I am using an OM13098UL which has the LPC54628 processor. My customer has a need to use USB1 as a dual roll host and device. I have exhaustively search the code examples from the latest SDK and although there are hints as OTG support I cannot find a formal API. Or at least one that jumps out at me. I am new to NXP SDK, but not new to embedded software. The SDK seems very well organized with fore thought with respect to ease of use. I would appreciate very much some pointers to code examples or documentation to get me started on the right path. Right now, I am floundering.
