I was charged to do a project with NXP LPC54618 that involves TCP/IP communication. They got me an example board with LPC54628 where I found (in the SDK) some lwIP working examples that got rid me from PHY init and other low level init stuff. In the actual project we changed PHY (LAN9303) and I need to understand the correct workflow for configuring at least the internal LPC's MII interface.
I also need to understand how to use fsl_enet (or fsl_phy).
I'm new to nxp microcontrollers/mcuxpresso, so I'm still not familiar with the architecture.
Until now, I've configured the pins (i hope) and searched some LAN PHY drivers. We're not running any RTOS.
