eth0 and eth1 on C6678

Vladimir,

I'd suggest starting with the MCSDK 2.0.  There's a Network Developers Kit (NDK) in the MCSDK 2.0

Here's a link to the MCSDK 2.0 info http://processors.wiki.ti.com/index.php/BIOS_MCSDK_2.0_User_Guide

Best Regards,

Hi Chad!

It's no problem with eth0, but eth1 can not be detected after POST:

TMDSEVMC6678L POST Version 01.00.00.02
FPGA Version: 000B
Board Serial Number: ECD0032999
EFUSE MAC ID is: 90 D7 EB 0B D6 86
SA is disabled on this board.

And eth1 can not be detected on Linux boot:

Where is eth1?

Can I work with eth1?

Vladimir,

Actually, I'll assume that it's Ethernet Port 1 that you're connecting to.  If you look through the EVM documentation you'll see that SGMII1 is connected via a switch to the RJ45 connector.  Etherenet Port 0 (SGMII0) is put out to the AMC header for SGMII connection across an AMC backplane.  You'd need to connect the SGMII up to another SGMII device such as a SGMII EMAC switch to communicate to that port on the EVM.

    On the EVM,the SGMII Port 0is put out to the AMC header for backplane ethernet. Now I have another board which has 1000BASE-X Ethernet on the AMC header . Can I connect the SGMII Port 0 to the 1000BASE-X (SerDes Ethernet)port across an AMC backplane? If not ,what  should I do ?

I'm wondering whether the SGMII port on the C6678 can connect to SerDes GbE(which mostly is 1000BASE-BX)?

Henry,

The answer would be.  Maybe.  If the GbE uses SGMII for the media interface then yes.  I believe if it's SerDes based then it would be SGMII, I'm not aware of another SerDes based GbE xMII.  That said 1000BASE-BX is a fiber interface, so I'd suspect the chasis would have a SGMII to (whatever fiber uses) Switch.  That's what I would suggest looking at to see what it is.

Best Regards,

Chad
