May I ask you some basic question(s)
booting MOTOROLA's FADS board by NFS
related to my last posting
http://lists.linuxppc.org/listarcs/linuxppc-embedded/200001/msg00086.html
<Question>
Q.1
At first, mbxroot.min.tgz can be used for FADS ?
Q.2
Why these messages is out?
(1)repeat of "NFS not responding" and "OK"
(2)"error in loading shared libraries" and
"libc.so.6: Out of memory"
[source]
mpc8xx-2.2.13
[NFS Server]
Linux 2.2.5-15 for i686 by Redhat ver 6.0
IP=192.168.0.254
defines client's name, MAC, IP, ... in /etc/bootbtab
Files in Root_Path are from mbxroot.min.tgz.
Those are sh and ls in /bin, /dev ,
ld.so.1, libc-1.99.so, libc.so.6 -> libc-1.99.so,
libtermcap.so.2 -> libtermcap.so.2.0.8,
libtermcap.so.2.0.8 in /lib.
[console]
When booting, cosole messages are:
..........................
eth0: CPM ENET Version 0.2, 00:00:85:30:30:31
Sending BOOTP and RARP requests.... OK
IP-Config: Got BOOTP answer from 192.168.0.254,

*: repeats about 20 times.
I tryed some times. About 20 is average value.
Meanwhile there are many transmissions
FADS's udp-port 800 ------> NFS server's udp-port 2049
128 bytes
FADS's udp-port 800 <------ NFS server's udp-port 2049
1132 bytes
I don't know NFS protocol in detail.
So I can't understand meaning of datagram.
