BSP Environment Variables (Compact 2013)
3/26/2014
You can use environment variables to define the level of support for a board support package (BSP) for Windows Embedded Compact.
After you update an environment variable, run MakeImg.exe to apply the change to your run-time image. If including a file or module is conditional on whether a variable is set, you must also add Romimage conditionals to code in the Platform.bib file. For more information, see Romimage Tool (romimage.exe).
There are two categories of BSP environment variables.
- BSP variables Set default information about a driver. For example, if your device uses an RTL8139 network interface card (NIC), set BSP_NIC_RTL8139 = 1.
- BSP_NO variables Set options that are not supported by a BSP or device. For example, if your device does not have a USB controller or USB host controller, set BSP_NOUSB = 1.
BSP variables
The following table shows BSP variables.
Environment variable |
Description |
|---|---|
BSP_CREDSVC_IN_DEVICE |
Enables the credential manager and sets it for operation in Devices.exe, even if the OS design includes Servicesd.exe. |
BSP_DISPLAY_FLAT |
Adds the FLAT display driver, Ddi_flat.dll, to the configuration. |
BSP_DISPLAY_MQ200 |
Adds the MQ200 display driver (Ddi_mq200.dll). |
BSP_DISPLAY_NOP |
Adds the stub display driver, Ddi_nop.dll, to the configuration. |
BSP_DISPLAY_RFLAT |
Adds the rotated-FLAT display driver (Ddi_rflat.dll). |
BSP_DISPLAY_S3V |
Adds the S3 Virge Display Driver. |
BSP_GLES2COMPOSITOR |
Adds the Windows Embedded Compact OpenGL compositor and OpenGL device driver. Requires SYSGEN_COMPOSITION. |
BSP_KEYBD_NOP |
Adds the stub keyboard driver to the configuration. |
BSP_NIC_AR6K_SDIO |
Adds the AR6000 Wi-Fi secure digital input output (SDIO) adapter. |
BSP_NIC_DC21X4 |
Adds the DEC21140 NDIS miniport driver. |
BSP_NIC_E100BEX |
Adds the Intel EtherExpress PRO Ethernet Network Driver for Intel i82559 PCI NIC. |
BSP_NIC_NE2000_PCI |
Adds the PCI NE2000 NIC driver. |
BSP_NIC_RTL8139 |
Adds the RTL8139 NIC driver. |
BSP_NIC_RTL8180 |
Adds Nativewifi RTL8180 wireless support and sets it to Access Point (AP) mode. |
BSP_NIC_RTL8180_STA |
Adds Nativewifi RTL8180 wireless support and sets it to the default Station (STA) mode. |
BSP_NIC_RTLNWIFI |
Adds the native Wi-Fi driver for the RTL8185 chipset. |
BSP_NIC_TIWLAN |
Adds the WLAN driver for TI WiLink 7.0 on OMAP4470. |
BSP_NOTIFY_IN_DEVICE |
Enables the notification subsystem engine for operation in Device.exe. By default, if this variable is not set and Servicesd.exe is included in the OS design, the engine runs in Servicesd.exe. |
BSP_PCCARDATADISK |
Uses Atapi.dll for ATA cards. |
BSP_SDHC_ELLEN |
Assigns the standard SDIO host controller to the TE4370 Evaluation Board. |
BSP_XRPLUGIN_DDRAW |
Includes the DirectDraw rendering plug-in, to support hardware acceleration with XAML for Windows Embedded. |
BSP_XRPLUGIN_OPENGL |
Includes the OpenGL rendering plug-in, to support hardware acceleration with XAML for Windows Embedded. |
