     3The GW5510 board does not have a standard ethernet port on it. Because of this there may be a desire to have a temporary ethernet port for flashing new firmware, etc.
     4
     5There are 2 areas USB Ethernet support may be needed:
     6 1. Bootloader - For flashing new firmware images
     7 2. Operating System - for standard connectivity
     8
     9Two drivers that are currently turned on in the bootloader are:
     10 * ASIX AX8817X
     11 * SMSC LAN95xx
     12 * Note: These drivers may not support all variants of those chipsets, please refer to the UBoot mailing list and source code.
     13
     14For other adapters, the driver will need to be added.

     16Gateworks has '''successfully''' used the following modules in their development

     21== Bootloader Support ==
     22For single board computers like the GW5510, a USB ethernet adapter is often used.
     23
     24Once the board is powered, break into the bootloader on the serial console.
     25
     26Type the command:
     27{{{
     28usb start
     29}}}
     30
     31The result should look something like this:
     32{{{
     33Ventana > usb start
     34starting USB...
     35USB0:   USB EHCI 1.00

     44
     45== Operating System Support ==
     46This will vary on operating systems and drivers may need to be added.
     47
     48== Mini-PCIe Ethernet Adapters ==
     49For certain situations, customers can also use a Mini-PCIe Ethernet adapter as shown here:
