Introduction; System Configuration - Wiznet W5300 Porting Manual

1. Introduction

The W5300 Linux driver is for the products which use embedded Linux OS. The W5300 can
originally use software protocol stack in OS kernel because it supports conventional MAC-RAW
mode and also it can use hardware TCP/IP stack simultaneously. We call this mode 'Hybrid
mode'. The Hardware TCP/IP socket has same meaning with Channel in <Fig 1>
This document is porting guide of Linux driver for new system. So it can be divided to three
parts as below.
Bus configuration

Interrupt configuration

W5300 Default configuration

In this guide, the examples of system settings are based on W5300E01-ARM board.

2. System configuration

If the circuit settings of W5300 are right, the MCU setting must be changed according to its
hardware. The circuit settings can refer to the document '6. External Interface' of 'High-
performance Internet Connectivity Solution-W5300'. In this section, the system setting is
generally set up at the bootloader and the kernel.
