Multiple interfaces working simultaneously on P1020RDB

Hi,

I can use all the three eTSEC controllers on my P1020RDB individually but I cannot use them all at the same time. My application needs to have more than one ports enabled at a time.

Has anyone got multiple eTSEC controllers working simultaneously on this board?

Thanks!

Multiple eTSEC controllers should work. May I know more details of the problem you are facing? When you said "..but I cannot use them all at the same time.", what does that mean?

Thanks for your interest.

It actually turned out to be a problem with my driver it was overriding the buffer descriptors in TBASE registers.

My use case is to run eTSEC2, eTSEC3 and one of the ports from eTSEC1 controller simultaneously. The bug in my driver was corrupting buffer descriptors for all of them that's why I wasn't able to get it going.
