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 
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


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.

In xapp902, they are using the old cores for Temac. So it will be easier 
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.

this is funny, but the wizard does not use hard temac , is it true? )
