Demo Image Componentes

The demo image is packed into the raw NK.bin file that is stored in the CM-X300 NAND flash during installation.

RAM

The CM-X300 supplied with the evaluation kit is equipped with 128MB of RAM. The demo image requires approximately 40MB and leaves 88MB for application use.

NAND Flash

The CM-X300 supplied with the evaluation kit is equipped with 512MB NAND flash. U-Boot and Eboot bootloaders are stored in the NAND flash.

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.

Space for a second runtime image is reserved to facilitate a fail-safe update mechanism.

Approximately 400 MB of free space is available for data storage on the NAND. Data may be stored in the NAND directory ("\nandflash").

Persistent Registry

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 with 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 flush period may be changed through the following registry value:

[HKEY_LOCAL_MACHINE\System\ObjectStore\RegFlush]
        "FlushPeriod"=dword:7530 

Networking

The following network interfaces are supported in the demo image:

• CM-X300 Ethernet - Full-featured 10/100 Ethernet interface. Implemented with the Davicom DA9000A Ethernet controller on the CM-X300 module.
• Wireless LAN - incorporates full-featured 802.11 b/g capabilities. Implemented with the Wi2Wi W2SW0001 WLAN controller on the CM-X300 module.

The demo image image is configured to use a DHCP server to obtain network settings for the two network adapters. Network settings may 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-X300 Ethernet controller:

[HKEY_LOCAL_MACHINE\Comm\DM9CE1\Parms\TcpIp]
    "EnableDHCP"=dword:0
    "IpAddress"="10.1.1.44"
    "Subnetmask"="255.255.255.0"
    "DefaultGateway"="10.1.1.1"
    "UseZeroBroadcast"=dword:0

A static IP may be assigned to the Ethernet interface using Eboot configuration menu. For further details please refer to Configuring Eboot article.

In order to run a custom application on the system startup, use the AutoLaunch utility integrated into the demo image.

The AutoLaunch utility extends the functionality of the HKEY_LOCAL_MACHINE\Init registry key and allowing configurable launch delay for each application. AutoLaunch monitors the following registry keys and values:

[HKEY_LOCAL_MACHINE\Startup]
	“Process0” =”Application.exe param1 param2”
	“Process0Delay”=dword:delay ;in milliseconds

[HKEY_LOCAL_MACHINE\Startup\ApplicationName]
	“Process0” =”Application.exe param1 param2”
	“Process0Delay”=dword:delay ;in milliseconds

Usage example:

[HKEY_LOCAL_MACHINE\Startup\ceplayer]
	"Process0” =”ceplayer.exe \windows\sound2.wav”
	“Process0Delay”= dword:1388 ;5000 in decimal

The above example launches CEPlayer five seconds after boot completion. The additional "\windows\Sound2.wav" parameter is used by CEPlayer to play the specified file.
