MPC5777C-DEVB and FEC ethernet

[alain_albert]

hi, I have the MPC5777c-DEVB board, ethernet does not work. I cannot see any LED lightning on my RJ45 connector. Can you help me ? do you have documentation on the MPC5777c-DEVB board other that quickstart guide ? Do you have any FEC code example configured in MII mode that run on this board ?

thanks

Hi,

the LEDs on RJ45 connector cannot light as both are not connected. You can check board' schematic on https://www.nxp.com/downloads/en/schematics/SCH-29962.pdf .

The TJA1100 is used here, it is 100BASE-T1 compliant PHY. So you should connect it to the T1 compliant PHY or have some media converter if want to connect to 100BASE-X compliant PHY

I am not aware of any demo example for this board, but I will try to ask Apps team for that.

BR, Petr

Hi Petr,

Thanks for your answer, I found out that I need to buy a converter to connect the 100BASE-T1 to 100BASE-X to see frames on my PC.
