3. Configuration Tool
3.1. Description
In order to configure the WIZ-iRadio, the Configuration Tool program should be installed and used.
Please download Install file from Software CD or WIZnet homepage (www.wiznet.co.kr)
.
Figure 7. WIZ-iRadio Configuration Tool
A. Module list : The MacAddress of all the modules on same subnet are displayed.
B. F/W version : It shows the firmware version of WIZ-iRadio module.
C. Status : It shows the connection status between module and server.
D. IP Configuration Method : It configures network-related parameters of the module..
zStatic
When using fixed IP,, input local IP, subnet, gateway, and DNS.
zDHCP :
When module is installed under the dynamic IP environment, select the DHCP. If
DHCP is selected, local IP, subnet, gateway and DNS are automatically configured.
zServer IP & Port :
Server IP and Port can’t be manually input. After selecting a channel at the Channel
list, it is connected to the selected site through DNS. Server IP and Port are
automatically displayed.

zChannel :
It displays the list saved in the file “Server_list.txt”. “Server_list.txt” is created in the
folder where Configuration Tool program is installed.
E. Search : It searches for all modules installed on same subnet.
F. Setting : It saves changed configurations.
G. F/W upload : It is for upgrading the firmware.
H. URLset : It saves changed channel information.
3.2. How to Use Configuration Tool - Examples
A. Changing Network Information
zClick “Search” button, and select a module at the “Module list”.
zConfigure network setting by changing the parameter values, and click “Setting”
button.
zThe module is reset and operates with changed values.

4. Firmware description
4.1. Firmware Structure
The firmware of WIZ-iRadio is composed of Application and Boot. The role of Boot is for updating
through the network. Therefore, JTAG ICE such as MultiICE is not required when developing. In the
WIZ-iRadio, STR710FZ2 from STMicroelectronics is used. In the Flash of this MCU, Application and
Boot firmware is written according to the memory map (below).
Application 0x40000000 ~ 0x40010000 Internet Radio Function
Boot 0x40030000 ~ 0x40040000 Used for firmware update through network
Table 4. Firmware Structure
4.2. Scat File
According to the memory map, the scat files in each App and Boot folders are written. The scat
file in the App folder is as below (please refer to Figure 8).
Figure 8. App – Scat

WIZ-iRadio User’s Manual

16
There are RAM_MODE and FLASH. In the case of RAM_MODE, it is used for operating at the
internal RAM after writing the F/W and downloading with JTAG device such as MultiICE. The
FLASH is used for operating after writing in the flash memory of STR710FZ2. You can select one
of them. For the not-used mode, mark it as commentary.
The program starts from 0x400300000 of flash memory at the Boot. The scat file in the Boot
folder is as below (please refer to Figure 9).
Figure 9. Boot - Scat
4.3. Compile Environment & Process
WIZ-iRadio is developed by using RealView and MultiICE of ARM. If the source file has ‘prj’
extension, it is the project file of RealView.
-. App : \App\REALVIEW\network.prj
-. Boot : \Boot\REALVIEW\network.prj
