CCS: DSP647 PHY and NDK

Tool/software: Code Composer Studio

The DM647 MAC is used to connect PHY 88E1111, just as reference design of DM647 with only one PHY.

After the project "HelloWord" ran on dm647 circuit board, NDK kept on looking for another PHY, just as it did

on DM648. furthmore, the ethernet interface of dm647 can't ping from another PC.

I wan to know:

(1) How to update DM648 ethernet driver to tell NDK dm647 has only one PHY?

(2) Where to find a simple testcase for dm647 ethernet?
