MPC5746C ENET On EVB MPC574XG-MB

Question asked by Hedi BASLY on Aug 28, 2018

Hello,

I'm Working with the MPC5746C on the EVB MPC574XG-MB, my current subject is send/receive frames over ethernet on RMII mode.

I used the exemple "MPC5748G-ENET_external_loop-test-GHS614".

on my EVB i have an external loopback cable (RX signals are connected to TX signals).

 

When i put The MPC5748G on the EVB, i compile the exemple and dwnload it to the board, the communication is working and the frames are sent/received, that seems to be good.

 

but when i put the MPC5746C on the EVB, the code does not run, so i created a new project on GHS and used the MPC5746C as target and i used the sources files from "MPC5748G-ENET_external_loop-test-GHS614".

 

on my debugging terminal i got this.

the code is running but the frames are sent and not received .....

 

am I missing something here. i verified the SIU pad config and it is correct... Any help would be appreciated.

 

my code is attached.
