Hi,
I have a Memec FG456 evaluation board with P160 module. I
am using Xilinx ethernet core (with default configuration
in mhs file) and the open source linux driver for Xilinx
EMAC. It seems that the ethernet device is detected
correctly but I cannot seem to ping any machine in my
network. I can ping myself though. Here are some diagnostic
results.
1) insmod the driver
bash-2.05# insmod a.out
eth0: Xilinx EMAC #0 at 0xFEFE8000 mapped to 0xC3008000,
irq=31
2) ifconfig
bash-2.05# ifconfig eth0 192.168.0.55
bash-2.05# ifconfig -a
eth0 Link encap:Ethernet HWaddr 00:60:08:27:11:7B

4) interrupts
bash-2.05# cat /proc/interrupts
CPU0

31: 7 Xilinx INTC Level eth0
BAD: 0
5) Running ethereal on host which I am pinging to, I can
see ARP requests from my linux target sent to the host but
nothing is sent back to target.
Any ideas on the source of the problem?
