The default location of <ZTP Installed Dir> is C:\\Program Files\\ZiLOG. 4. Select Build Set Active Configuration to open the Select Configuration dialog box, and select the RAM configuration. 5. From the Project menu in ZDS II, select Settings. The Project Settings dialog box appears. 6. In the Project Settings dialog box, select the Debugger tab. In the Debugger tab, ensure eZ80F91_WiFi_RAM option is checked and the correct debug tool is selected. In this Demo, USB Smart Cable is used as the Debug Tool. 7. Click OK to close the Project Settings dialog box. If the ZDS II prompts to Rebuild the Project, click YES to enable the configuration on Project Settings. 8. After the successful build, ru n the Demo application using Debug Go. This is observed on Hyper Terminal window: Initializing SPI Initializing SDIO card get SYSCLKR=c0000000 set SYSCLKR=c0000003 get SYSCLKR=c0000003 RTL8711_3rdCUT SYSCTRL : 68 !

To support FLASH and COPY_TO_RAM configuration on Wireless Zdots SBC (due to new external SP ANSION Flash) ZDS II Flash driver configuration file must be modified. Replace the FlashDevice.xml the file given in the WLANDemo folder. In the Project Settings Debugger; eZ80F91_WiFi_Flash must be selected for FLASH and COPY_TO_RAM configurations. After replacing the FlashDevice.xml file close all ZDS II instances and reopen again. 2. By default the wlan_conf.c file contains WLAN parameters set to zero. In this case, you can configure these parameters through shell and connect to a BSS (AP). 3. If the WLAN parameters in wlan_conf.c are valid (that is, not initial- ized to NULL), the Demo connects to the specified BSS (AP) without the user interaction. 4. In FLASH and COPY_TO_RAM configurations the SSID and WEP key can be set through the configwlan shell command. For more details, refer to Zilog TCP/IP Software Suite Programmer’ s Guide (RM0041). 5. The Zdots® WLAN solution cannot be configured to work as an Access Point. Web Server Demonstration Follow the steps below to use the features of WLAN Demo: 1. When you run the WLAN Demo applica tion Zdots SBC accesses the BSS with the specified SSID and displays the network parameters such as IP address and a login prompt on the HyperTerminal. You can type help on the prompt to know other command line applications. 2. Use ping command from any PC in the same BSS/ESS as Zdots SBC running ZTP. Ping command can be used from Zdots SBC shell to other PC also. 3. Open an Internet Explorer from a PC/laptop where the router is connected and browse the eZ80® WLAN Zdots SBC with the IP specified on the Hyper Terminal. In this IP Address may vary. Please verify this value on IP addr on the hyperterminal. Notes: Note:
