7 Design of lwIP Integration

The integrated software deliverable consists of four main layers:

  • Hardware Abstraction Layer (HAL): EMAC and MDIO HALs are part of the HALCoGen release and the PHY HAL is part of the application.
  • lwIP Network Interface Layer – Hercules NetIF port for lwIP
  • lwIP Application Layer – An IP stack application based on lwIP. Examples are provided for HTTP server, UDP based client and echo server. The packets start and end at this layer.
  • System Application Layer – This includes the system initialization and is generated based on the HALCoGen GUI. This layer configures the PLLs and PINMUX.
