Timing fails with two TSE MACs

Hi everyone, I'm working on a DBC3C40 board and I'm building a system based on the TripleSpeedEthernet sample. I need to use both Ethernet PHYs available on the board, so I added a second TSE MA...

Sorry, but I posted some wrong information

Actually the timing issue is present with the single TSE MAC, too, but in this case all works fine.

Is this normal? or should I work to avoid the timing warning?

Second point: why the first MAC stops working and the whole system gets stuck whenever I add the second MAC?

Maybe an error in the connection to the Nios, base addresses or interrupts?

Note that so far I'm not really using the second MAC, neither I initialize it; the Nios app is exactly the same. I simply added it in SOPC builder, generated and recompiled the fpga core and rebuilt syslib and application.

I think I made some silly mistake but I'm a very beginner and I can't find out it.

Regards
