How to make eZ80 Webservers configurable online, update its website contents and the firmware

v 1.6

Date: 02.07.2002 - 16.09.2002

The Command Protocol structure. The v.1.6. release is called "New Generation". This release is major rewrite of the UDP control thread. The goal is to make the command processing in universal way. The control thread contains the UDP receive loop as before and as before it makes call to udp_parse_cmd function. The udp_wait flag is added after the call to syncronize with binary downloads (TCP data threads). The change is made in the udp_parse_cmd function. Now it contains a general loop that compares the contents of the datagramm received with the members of the ezconfig structure of the type struct CommandProtocol. This structure contains three fields: the command name, the function to execute on the command receive and the help string for the command line user interface convenience. The number of commands in the structure is given by the
  const int num_commands;
variable.

The Application Header. At the 8 byte offset after the program start there is an area where application header resides. Every application that wants to be compatible with the eZ80 Remote Access should declare this header. The header structure is as follows.
  eZRA - the identifier, 4 bytes
  application size - the size of code in ROM, 4 bytes
  application name - the name of the application, arbitrary size

  • 21.11.2002 NetBooter Release 1.6.6 for IPWorks 1.3.2
    It is important to leave this archive working because it was the first full featured release. Now recreating the Release based on the new generation idea.

    Features:

    Project Structure:
    The project consists of configuration files, source files, libraries and header files. The header files of the Remote Access Server are in include directory. The project file is in the netboot/realtek directory which peflects the version compiled for the eZ80 Realtek board. The source directory contains all necessary source files to configure the project and adjust it for specific user needs.

    The ipworks directory provides the version 1.3.2 of IPWorks. The set of includes, libraries and stubs eliminates the necessity to install that over again.
