RTOS/TDA2PXEVM: supporting Marvel Ethernet

Part Number: TDA2PXEVM
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

Hello All,

We need to support the custom board based on TDA2Px which will be having ethernet device 88Q2110 connected at RGMII1 interface.

 . The custom board is also having another ethernet device DP83867RPPAP connected to RGMII0 interface.

We need to support both simultaneously. Can you please provide any reference on how to support this device

We are using PSDK3.03 with sysbios all configuration

regards

Hrishikesh

    Hello Hrishikesh,

    Do you want to use both ports as separate interfaces or as a switch?
    If as a interfaces then it is not supported in the current network driver of VSDK. For adding support for new PHY you can refer to below

    Hi Prasad 

    Thanks for the reply,

    Please let me rephrase the querry as follows

    As per client application requirement we intend to bring two Ethernet interface on custom board with TDA2px.
    Configuration is as below.
    1)      RGMII0 interface shall use PHY DP838867 . This port to be used as debug port . ( support is available on TDa2x –EVM )
    2)      RGMII1 interface shall use PHY Marval 88Q2110. This port to be used for connectivity with vehicle network.
     
    Query
    1)      How to enable simultaneous two Ethernet support for TDA2px with vision SDK 3.03.00.00, SYSBIOS
    2)      With reference to TI forum link  e2e.ti.com/.../615336 it is suggested to do the changes in  file  ndk_nsp_hooks.c in vision_sdk/src/utils_common/src/ndk.  This refers to change of phy module as per our understanding.
    Do let us know is it correct understanding?
    3)      For enabling another interface what changes required in vision SDK3.03.00.00 and location of the SW components.
    4)      What changes are required to enable interface in NDK to have Ethernet interface available for application.

    Hello Hrishikesh,

    1) How to enable simultaneous two Ethernet support for TDA2px with vision SDK 3.03.00.00, SYSBIOS

    >> Simultaneous usage of both ports is not supported on VSDK BIOS. With current SW you wouln't be able to use both ports simultaneously. Only one port can be used.
    Dual MAC (2 ports) is supported on Linux, so if you want to use this feature you would have to use VSDK Linux.
