The role of two EMACs on xtcievmk2x board

Hi,all:

I note that there are two EMACs port on xtcievmk2x board.One is red color and the

other is blue color like below:

My question is that :

What's the role of the two EMACs? Does the red one used by ARM and the blue one used by DSP-6678?

I think my guess seems ok. Because when I worked on ARM I used the left one/red one to rx/tx data.

Isn't it?

How can I get the mac address of the two EMACs?

what's the mac address of the red one?

So is the blue one?

Any help will be appreciated.

Hi,

Yes, dual Ethernet ports on board.
Get more details at technical reference manual,

For 66AK2Hx Evaluation Modules:
The EVM is enabled with two 10GB Ethernet interfaces for a bandwidth of 20Gbps backplane connectivity
and optional wire rate switching in high density systems.

Hi,Pubesh:

Before I have seen that TRM docment but I cannot find the answer.

Would you answer my above two questions directly ?

That TRM docment doesn't say which ethernet port of those two ethernet ports

can be used by ARM ,which ethernet port can be used by DSP?

What's more,that TRM docment doesn't say how to get the mac address

Hi,

Yes, it is not mentioned, which port will be used on this EVM.
Here I like to share one thing, there is no idea for one port support for ARm and another for DSP.
Both ports you can be used for ARM and DSP. I think so, you can use working port for ARM as well as DSP.

I will check for one of the non working port which is mentioned by you.
