OMAP4 Ethernet Driver Issue

Shaan
Intellectual 450 points


Hi,

            We wanted to try ethernet over usb on  on Blaze Tablet ( OMAP4460 processor running ICS android version) . I have a ASIX USB ethernet dongle and want it to be interfaced. Is there any steps available which i can use to bring up the ethernet interface.

The primary reason for going to USB ethernet is because the existing ethernet driver supports only upto 2Mbps throughput which is limiting our application. Any help on this is highly appreciated.

 

Thanks nad Regards,

Shantanu Bhaduri

    Shantanu,

    There is an application note that describes in detail how to use a USB-Ethernet adapter with the Blaze Tablet and how to obtain throughput measurements.  You can contact your TI representative for access to this document.  To summarize the key steps:

    1. Apply these patches to your kernel.  I believe that all but the last patch are already included if you are using the 4AI.1.6 release.  (These are needed to improve throughput performance, but are not required for basic USB-Ethernet functionality.)

    2. Enable CONFIG_USB_USBNET in your menuconfig.  (This option is located in:  Device drivers --> Network device support --> USB network adaptors -> Multi-purpose USB networking framework.)

    3. Connect a self-powered USB hub to the USB OTG or EHCI port on the Blaze Tablet via the micro-A or standard-A USB cable, respectively.  You should see detection messages on the serial terminal.

    4. Connect the USB-Ethernet adapter to the self-powered USB hub.  You should see detection messages on the serial terminal.

    Let me know if you have any further questions.
