Re: [openrisc] How to make ping work on or1ksim

[youwenyi@attbi.com]

Hi,

After I sent out the question on how to run ping on or1ksim, some
people told me they have the same problem and asked me whether I 
have solved the problem. I have finally figured out how to do that. 
Here is how:

1. Use "--enable-ethphy" as option when "configure" or1ksim.
2. Assume your LAN subnet is 192.168.0.0/24. Go to or1k/romfs/etc,
   edit "rc" to be
   ifconfig eth0 inet 192.168.0.9 netmask 255.255.255.0 hw ether 
00:11:22:33:44:55
   route add -net 192.168.0.0 netmask 255.255.255.0 dev eth0
3. Run genfomfs, and compile uCLinux.
4. Run or1ksim as root. (It took me a lot of time to figure this out! )
5. Run "ping 192.168.0.9", you should see loop-back reponse.
6. Assume another host on LAN is 192.168.0.1, run
   "ping  192.168.0.1". You should see ping reponse from that host.
