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.

Subject: RE: ML403 Hard TEMAC, PLB
and Linux 2.6
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

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.
