8 Release Folder Structure

The lwIP demo software supports eight different variants. The folder for each variant contains the following:

  • Build folder: This contains the CCS project that can be imported into your workspace and built.
  • HALCoGen folder: This folder contains the source and include folders generated using the latest version on HALCoGen.

NOTE

  • The 'Build-xx' folder contains the CCS project for the device.
  • The 'HALCoGen-xx' folder contains the HALCoGen generated driver files for the device.
  • The 'doc' folder contains manifest and user's guide.
  • The 'example' folder contains a port of the lwIP example.
  • 'lwIP-1.4.1' contains all the lwIP library files.

The active web server demo software supports two different variants. The folder structure is similar to the lwIP demo. In addition,

  • The 'fs' folder contains the html file and Java script to generate webpage file.
  • The 'tools' folder contains makefsfile utility.
  • The 'utils' folder contains lwIP related initialization code.
