How to use MPC5748G ethernet switch ?

[dukaizhu]

There are three MCU on my board,  they are MPC5748G,  MPC5777M(MCU0)  and MPC5777M(MCU1) .  They are interconnected through MPC5748G ethernet switch module.   MPC5777M(MCU0)  and MPC5777M(MCU1) are connected to MAC-NET0 and MAC-NET1,   then I want to ask the follow questions.

    1.   Can MCU0 and MCU1 communicate through MPC5748G ethernet switch module ?

    2.   Can MPC5748G connect to MPC5777M through  MII interface without PHY ?

Hi Kaizhu,

1. Yes, that's possible

2. This was already discussed here:

networking - Can two Ethernet MAC chips be connected directly (without going thru PHY)? - Stack Over...
