lwIP Integration

Overview

Use this skill to integrate lwIP by separating hardware Ethernet/Wi-Fi drivers, netif glue, memory pools, threading model, and protocol configuration. A successful port proves link, IP configuration, packet RX/TX, and resource stability under load.

When To Use

Use this skill when:

• The user wants to add or debug lwIP on bare metal, FreeRTOS, RT-Thread, Zephyr, vendor SDKs, or custom network drivers.
• The issue involves lwipopts.h, sys_arch, netif, DHCP, TCP/UDP, pbufs, memory pools, packet loss, or hard faults in networking.
• The target uses Ethernet, Wi-Fi, PPP, SLIP, or a vendor network interface.

Do not use this skill when the physical link or board interface is not proven. Use hardware-interface-debug first for PHY, RMII/MII, clocks, or wiring issues. For FreeRTOS-native TCP/IP, use freertos-plus-tcp-integration. For MQTT over lwIP, use mqtt-embedded-integration after basic connectivity works.
