Configuring Multiple Ethernet Cards for a CEPC

  • Article

You can set up a CEPC with a debug Ethernet card and one or more product Ethernet cards. The following steps show how to configure a CEPC that has multiple Ethernet cards.

To configure multiple Ethernet cards for a CEPC

  1. In Platform Builder, when you use the integrated development environment (IDE) to set up your Windows CE–based platform, set the following environment variables:

    • KERNELNOSHAREETH=1
    • BSP_NOSHAREETH=1

    These settings disable the VMINI Ethernet sharing library. This library supports the sharing of a single Ethernet card on a CEPC between debug and application traffic. For information about setting an environment variable in the Platform Builder IDE, see Setting or Clearing an Environment Variable.

  2. Verify that your platform includes support for the type of product Ethernet card that you installed on your CEPC.

    For information about how to verify that a platform includes support for an Ethernet card, see Building a CEPC OS Image for Use with an Ethernet Card.

  3. If your platform does not include support for the product Ethernet card, add support for the product Ethernet card.

    For information about how to add support for an Ethernet card, see Building a CEPC OS Image for Use with an Ethernet Card.

  4. To build your platform, from the Build menu, choose Build Platform.

  5. In the BIOS for the CEPC, verify that the interrupt used by the product Ethernet card does not conflict with the interrupts used by other PCI cards.

    You should be able to change the value of interrupts in the BIOS. For more information, see Configuring the BIOS on the CEPC.
