sorry for the self-reply, but pinging from the minimodul increases the
interrupts :-)
can you tell me the changes in the driver file ?
thanks

Hi Neeraj Garg,
First look at ethernet interface RJ45 connector that power is coming,
LED should blink.
Yes, LEDs are blinking, an if a cable is connected the link leds are
on. while pinging from the host pc the traffic led in front of the
jack is blinking also
1) check whether IRQ is right, its zero in your case. If it is right
then issue ping and read interrupts arriving on your ethernet
interface (cat /proc/interrupts), If number of interrupts are
increasing then its sure that your PHY is ok , the problem is with
mode selection (10 MBPS, or 100 MBPS) if that is the issue let me
know , I'll tell you where to make changes in driver files.
no interrupts on eth0:
0: 0 Xilinx Interrupt Controller Edge eth0
1: 889 Xilinx Interrupt Controller Level serial
2) If nothing of the above works then there is problem with PHY
address detection. You have to look in hardware specification (your
hardware board ) to find out PHY address.
Yes, i will try this. i use this board with the edk 8.2 a year ago.
with this edk version the emaclite was working fine. but in this
project there was an ip core "Hard Temac" this is missing now. i think
i have an error in my edk project.

Hi again,
mmh, there is no kernel message with PHY detection, but all PHY
drivers are compiled in.
i looked at my xps project and there is only one ip-core
"Ethernet_MAC" with type "xps_ethernetlite".
is it possible that the phy connection is missing ? i use the base
system builder with the board support files supported from avnet.
where can i look for the ethernet speed ? the ethernetlite ip has no
speed options
thanks for your help

Hi Georg,
Can you post linux bootup message where its says PHY is detected at
paticular address, and check with your hardware what is actual
address of PHY. Also I would like to know the configuration of your
hardware whether its configured of 10MBPS OR 100MBPS.

Hi all,
im trying to use the emaclite core which comes with the EDK10.1
with the 2.6.26 kernel from git.xilinx.com on virtex4fx12
minimodul. the emac is detect by the kernel:
xilinx_emaclite xilinx_emaclite.0: MAC address is now 2: 0: 0: 0:
0: 0
xilinx_emaclite xilinx_emaclite.0: using fifo mode.
xilinx_emaclite xilinx_emaclite.0: Xilinx EMACLite at 0x81000000
mapped to 0xC5060000, irq=0
i can change the mac-address with ifconfig and i can give an
ip-address to the device,
but a ping is not possible and arp is not working. i think that the
phy is not working right.
has someone others the same problem ? what can i changed ? i have
tried out all possible phy driver in the linux kernel
a setup with the lltemac is working fine, but i want to use the
emaclite
thanks
regards
georg
