5.1. Memory Map

The memory map of WIZ-Embedded WebServer is composed of 128Kbyte code memory and 64Kbyte data memory. The data memory is composed of internal SRAM and W5300. In addition, 4Kbyte EEPROM is built in AVR. Environment variables of the board are saved in this EEPROM.

Below figure shows the system memory map of the test board.

Figure 24. WIZ-Embedded WebServer Memory Map

5.2. WIZ-Embedded WebServer Firmware

The firmware performs ProcessWebServer, ProcessDhcp and ProcessConfig in the main() Function ProcessWebServer() operates as webserver. It processes HTTP protocol from web browser, reads the web page in the Flash memory, and sends it. ProcessConfig() function processes network related configuration. ProcessDhcp() function does DHCP related functions.

5.3. Compile

The sources mentioned in the Chapter 5.2, are compiled by aligning in the SRC. The firmware compile can be performed by using WINAVR and AVRSTUDIO. Install the WINAVR and AVRSTUDIO in the PC. For the easy working, open the firmware project file "~/main/ex03_webserver/wiz-web.aps” through AVRSTUDIO project file. Check compile setting of Configuration option of ‘Project’ menu. For the setting method, refer to ‘AVR Studio User Guide’. The firmware provided by WIZnet is based on AVR-GCC 3.4.6. In another version, the operation can be abnormal.

Figure 25. AVR Studio

When compile is completed, hex file is created in the folder that user defined before. This file is programmed to ATmega128.

5.4. Downloading

For the Hex file downloading, use AVR Studio and AVR ISP cable.

WIZ-Embedded WebServer User’s Manual

29

1) Connect the AVRISP cable to J9 of the Base Board.

2) Connect the power adaptor and turn on the switch.

3) Execute AVRStudio.exe

4) Select Atmega128 at the Device section

5) Select HEX file at the FLASH section

6) Click Program button.

For more detail, refer to ‘AVR Tool Guide.pdf’.

Figure 26. ATmega128 ISP

In order to update the firmware through network, the bootloader should be programmed first. Bootloader is written to be input at 0x1E000. For the re-programming the firmware file, remove the Atmega128 and program the ‘Boot.hex’ file. At this time, do not check the option of “Erase Device Before Programming” for not removing the bootloader.
