Demo Image Components
The demo image is packed into the raw NK.bin file that is stored in the CM-T3530 NAND flash during installation.
The CM-T3530 supplied with the evaluation kit is equipped with 256MB of RAM. The demo image requires approximately 96MB of RAM and leaves 160MB for application use.
The CM-T3530 supplied with the evaluation kit is equipped with 512MB NAND flash. XLDR and Eboot bootloaders are stored in the NAND flash. Demo image installation process partitions the NAND flash and reserves unpartitioned space for the runtime image.
During demo image installation, the NAND flash is automatically partitioned and space is reserved for the runtime image, which is stored in the NAND flash unpartitioned space.
Approximately 480 MB of free space is available for data storage on the NAND. Data can be stored in the root directory ("\My device").
The demo image is built with a “Hive-Based Registry” option. This means that the system registry is stored in the NAND flash data partition, making registry entries persistent when the device is powered off. The demo image is configured according to a “Lazy Flush” registry policy. The registry settings are stored in RAM and are flushed into the NAND flash every 30 seconds. After changing registry settings, allow 30 seconds before turning off the power or performing a hardware reset. This will ensure that the changes are saved into the NAND flash.
The following network interfaces are supported in the demo image:
- CM-T3530 Ethernet - Full-featured 10/100 Ethernet interface. Implemented with the SMSC LAN9220 Ethernet controller on the CM-T3530 module. The interface is routed to connector P18 of the SB-T35.
- SB-T35 Ethernet - Full-featured 10/100 Ethernet interface. Implemented with the SMSC LAN9220 Ethernet controller on the SB-T35 base-board. The interface is routed to connector P16 of the SB-T35.
- Wireless LAN - incorporates full-featured 802.11 b/g capabilities. Implemented with the Wi2Wi W2SW0001 WLAN controller on the CM-T3530 module.
The demo image image is configured to use a DHCP server to obtain network settings for the three network adapters. Network settings can be changed in the Windows CE Control Panel.
Defining static IP address
It is possible to configure a static IP address by modifying the registry.
For example, the following registry settings disable DHCP and define the static IP 10.1.1.144 for the CM-T3530 Ethernet controller:
[HKEY_LOCAL_MACHINE\Comm\SMSC91181\Parms\TcpIp] "EnableDHCP"=dword:0 "IpAddress"="10.1.1.44" "Subnetmask"="255.255.255.0" "DefaultGateway"="10.1.1.1" "UseZeroBroadcast"=dword:0
- Connector P17 provides 2 USB host ports that operate at high/full/low speeds.
- Connector P8 provides a USB device port (used mainly for ActiveSync).
- Connector P21 provides a high speed USB host port.
- The SB-T35 evaluation board feauters SD socket (connector P13).
- When an SD card is inserted it is mounted automatically as “Storage Card” under “My Device”.
- The demo image has been tested successfully with the following types of SD cards: SanDisk Ultra III 2Gb, Kingston 2Gb, SanDisk 1Gb, and Kingston Micro SDHC 4Gb.
The demo image is calibrated for the Toppoly TD035STEE1 LCD touch screen. To fine-tune the calibration, run the touch screen calibrator by tapping Start >> Settings >> Control Panel >> Stylus >> Calibration. For further details about touch screen calibrator registry settings refer to the Touch Screen (Stylus) Registry Settings MSDN article.
The CM-T3530 image supports a generic 36 (6x6) button keypad.
