Thanks for the reminder from Wolfgang. I tried to send my first post to
this list in html format and got failed. Now I redo my post and hope to
get some help from you.
Hi Guys,
I am new to both this mailing-list and embedded linuxppc. Currently I
am working on IBM ebony evaluation platform, and I got couple of doubts
which I can't figure out. I programmed u-boot 3.0.0 into the flash and
trying to use NFS to boot the kernel. Here are my questions,
1. At U-Boot phase
I got output on console:
U-Boot 0.3.0 (Apr 15 2003 - 14:12:33)

=>
Why u-boot failed on my DRAM I2C read although it still can find out the
correctly amount ?
At this point of time, I am not able to ping the target from my host(RH
7.3). From the host:
root at Jeff u-boot-0.3.0<1063>ping 7.1.1.6
PING 7.1.1.6 (7.1.1.6) from 7.1.1.4 : 56(84) bytes of data.

eth0
I guess that dear Ms. U-Boot does not bring up arp, is that correct?
2. Now, I am trying to tftp kernel image, and on target console:
=> tftp
ENET Speed is 100 Mbps - FULL duplex connection
ARP broadcast 1
TFTP from server 7.1.1.4; our IP address is 7.1.1.6

Ok, she got the image.
On host side, I have:

eth0
Ms. U-Boot looks more pretty and coorprative now, right? But I still
couldn't ping her,
root at Jeff u-boot-0.3.0<1066>ping 7.1.1.6
PING 7.1.1.6 (7.1.1.6) from 7.1.1.4 : 56(84) bytes of data.

3. Now I am trying to boot up kernel, she says:
=> bootm

Look, Mrs. U-Boot bring up the kernel and Mr. Kernel talks lot but he
stucks here refusing to move ahead. Seems like kernel didn't get his MAC
address properly, so he couldn't connect to host bootp server. My
question is that how does Ms. U-Boot pass the environment variable to
Mr.
Kernel, as something I got from this archive?

4. Then I issued a ping from host,
root at Jeff u-boot-0.3.0<1068>ping 7.1.1.6
PING 7.1.1.6 (7.1.1.6) from 7.1.1.4 : 56(84) bytes of data.

This makes Mr. Kernel keep going:

Looks like the kernel got himself's MAC through the icmp message. It is
fairly wired to me.
At this moment, on host:

You will see Mr. Linux Kernel tries to cheat the host by a wrong MAC
address.
Below is my environment variable settings special for dear Ms. U-Boot:
