USB Ethernet Adapters

The 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.

There are 2 areas USB Ethernet support may be needed:

  1. Bootloader - For flashing new firmware images
  2. Operating System - for standard connectivity

Two drivers that are currently turned on in the bootloader are:

  • ASIX AX8817X
  • SMSC LAN95xx
  • Note: These drivers may not support all variants of those chipsets, please refer to the UBoot mailing list and source code.

For other adapters, the driver will need to be added.

Gateworks has successfully used the following modules in their development

Bootloader Support

For single board computers like the GW5510, a USB ethernet adapter is often used.

Once the board is powered, break into the bootloader on the serial console.

Type the command:

usb start

The result should look something like this:

Ventana > usb start
starting USB...
USB0:   USB EHCI 1.00
scanning bus 0 for devices... 2 USB Device(s) found
USB1:   USB EHCI 1.00
scanning bus 1 for devices... 1 USB Device(s) found
       scanning usb for storage devices... 0 Storage Device(s) found
       scanning usb for ethernet devices... 
Warning: asx0 using MAC address from net device
1 Ethernet Device(s) found

Operating System Support

This will vary on operating systems and drivers may need to be added.

Mini-PCIe Ethernet Adapters

For certain situations, customers can also use a Mini-PCIe Ethernet adapter as shown here:
