TDA3LX: About conenct PC via Ethrnet

user4975810
Intellectual 445 points
Part Number: TDA3MV

Hello,

We are trying to connect to LAN with PC using custom board with Vision-SDK 3.02 and TDA 3 (different configuration from EVM).

TDA 3 recognizes that there are two pins for ETHERNET, RGMii 0 and RGMII 1.
Where should I change to switch between RGMII 0 and RGMII 1?

Also, although the AR8031 installed on the EVM board seems to be compatible with 1000 BASE - X and 100 BASE - FX, where can I switch this function?

* We are planning to give RGM II 0 and RGM II 1 different functions in the future respectively.

Thanks and regard.

    Hello,

    Does your board have both Ethernet ports populated? If yes, you should be able to use either of them by simply plugging LAN cable. Driver takes care to initializing network on port where LAN cable is connected.

    To change speed setting, you need to modify it in GMACSW_getConfig function of  vision_sdk\src\utils_common\src\ndk\ndk_nsp_hooks.c.

    >>>We are planning to give RGM II 0 and RGM II 1 different functions in the future respectively

    Do you mean you would be using both ports simultaneously? If yes, it is not supported currently and stack can run only on one port unless you want to use it as switch which is supported.
