Dear Massimiliano
Well I do not know the solution to the problem, but just,
In your post, there is some thing interesting for me,

How could you implement such large circuit on one FX12 FPGA?
We have done many experineces with both of AVNET MM and ML403,

you have, DDR SDRAM Controller, GPIO, UART, SYSACE and two intances of Tri-mode TEMAC GMII, 
In our tests, with one instance of Tri mode TEMAC and UART and DDR controller, the whole FPGA resource were consumed we could not even put sysace interface.

For me, another important question is, how many PHY chips are available on your board? Each of Tri-mode temac modules are connected to a separate phy chip, yes?

Hi,
The first thing I would try is to make sure eth1 comes up without first bringing up eth0.  In other words, does it come up independently?  If not, there could be something wrong with its configuration in the kernel or perhaps a hardware design issue.  If both interfaces come up independently, but not together, then there’s likely a driver issue as we have not tested dual channel TEMAC with the Linux plb_temac driver.  Perhaps others on the list have.  The areas that I would look at would be:  make sure each interface is getting a unique and correct PHY address; make sure any calls to the shared registers of the two channels are protected with semaphores/spinlocks.  For example, I’m pretty sure the PHY registers are shared, so any PHY accesses should be protected.  I would think other Xilinx driver accesses like Start/Stop/Reset/Get or SetOptions/etc… should be protected as they may access shared registers.
-Rick

Hi, we are trying to use both side of an hard temac + 2 plb temac in a Virtex4FX12 project.
we succesfull implemented a single temac Montavista tree with eth0.
when trying to use both temac, devices are correctly registered with kernel-
eth0 comes up and working ok-
when manually start eth1 (/sbin/ifconfig eth1 up) kernel hang without any error or info in the console

RE: ML403 Hard TEMAC, PLB and Linux 2.6
Hi,
As Ming says the Linux 2.6 TEMAC driver is made available in EDK 8.2.2 as part of the BSP and Libraries generation for Linux 2.6.  Note that we made a recent fix for better PHY address detection and speed negotiation. I've attached the adapter here, and it will be available in EDK 9.1.1 when that's released.
Thanks,
Rick

Hi,
In xapp902, they are using the old cores for Temac. So it will be easier to
generate a project in EDK 8.2. Not only the cores there are new, but also
it can generate the driver for linux 2.6.

You can start from XAPP 902 from Xilinx, this design demonstrate TEMAC
use in loopback mode. Some memers from that community have tried from
that design as a starting point. I did not nknow if the succeed.
I would recommand to get EDK 8.2 SP2 and use the Wizard to build a new

For the kernel you can get it from Montavista source code site using
GIT
quoted
quoted
to download it (linux-xilinx-26). This is 2.6.17.4 version (last week!)

Then you will need to pacth the Kernel with TEMAC drivers (look for
TEMAC PAULUS MVISTA with google, or follow my messages in that mailing
list)
NOTE: If you use that TEMAC patch do not use SGDMA on your TEMAC, use
FIFO.

Well, our board is a custom board and we have no problem on inplementing 
both TEMAC.
we have 
2 TEMAC with related separated hw phy.
sdram controller 
can controller
2 uartlite
sysace
graphics lcd interface
and other custom peripherals
external peripheral interface
no problem to fit into FX12..
