Hi Neeraj Garg,

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

no interrupts on eth0:
0: 0 Xilinx Interrupt Controller Edge eth0
1: 889 Xilinx Interrupt Controller Level serial

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.
