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

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?

From the diagnostic results cited above it looks like the
problem is in your host: the tagret sends 7 ARP requests
which are decoded correctly (I assume this because neither
you nor you host complain about ARP requests contents), but
host doesn't respond to them.
I would check the ARP requests contents and then your host settings.
Best regards,
Andrei

Hi Andrei,
After my original message, I set up system arp cache
manually for both host and target so they dont need to send
any arp requests. Using tcpdump on the host I sniffed the
ping requests and the host seems to respond to the ping
requests from target but target never receives them.
Here are my results (192.168.0.55 is the target and
192.168.0.5 the host)
Ontarget
--------
arp -s 192.168.0.135 00:0D:56:C5:8E:E2
ping 192.168.0.135
On host
-------
[root@ws054 tmp]# tcpdump icmp
tcpdump: listening on eth0
13:55:09.676075 192.168.0.55 > 192.168.0.135: icmp: echo
request (DF)
13:55:09.676153 192.168.0.135 > 192.168.0.55: icmp: echo
reply
13:55:10.677428 192.168.0.55 > 192.168.0.135: icmp: echo
request (DF)
13:55:10.677462 192.168.0.135 > 192.168.0.55: icmp: echo

So it seems that TX for EMAC is working fine but there are
issues with the RX side. I would like to add that I am not
using the patch that you sent few days back.

Shamile
