Does the NSP support the DP83848YB Transceiver?

Other Parts Discussed in Thread: DP83848YB, OMAPL138

Hi,

I've got a question according to a certain PHY we are using on our board, The PHY is the DP83848YB by TI. We've tried to build a simple UDP client using the EVM6748 from LogicPD. The application works fine on the evaluation board and we are able to receive data on the PC-side, but when  the same application runs on the custom board which has the mentioned PHY, no data is sent via ethernet. It seems that the PHY is simply not supported. Is there any code out there which adds support to NSP / NDK for this transceiver? If we have to port this device to the NDK is there any guideline what describes what to do? http://processors.wiki.ti.com/index.php/Guidelines_when_porting_NDK_to_different_PHYs seems to be a little bit outdated?

Any help on this issue would be very appreciated. Please let me know if you need additional information...

NDK Version is 2.20.6.35

NSP Version is 1.10.0.03

Kind Regards,

Steve

    Hi Steve,

    The OMAPL138 uses a SMSC LAN8710 Ethernet PHY (http://support.logicpd.com/downloads/1231/).  I don't believe we have support any driver support for the DP83848YB PHY.

    Have you seen this guide? It may help you:

    - TMS320C6000 Network Developer's Kit
    (NDK) Support Package Ethernet
    Driver Design Guide

    • This document discusses the Ethernet driver design
    • You can find this in your NDK installation, for example on my machine, it's here:

    C:\Program Files\Texas Instruments\ndk_2_20_04_26\packages\ti\ndk\docs\stack\sprufp2_nspethdrvdesign.pdf

    Hi Steve,

    thanks for your answer and sorry for the late response, I was busy on another subject till now.

    We decided here to redesign our board and we will use now the PHY from SMSC since this device works well with the NDK...

    Thanks again!

    Kind Regards,

    Steve
