hi

after upgrading my toolchain and u-boot sources to CVS 1.0.2 version I 
still can't manage to get 'clean & fast' downloads of kernel image from 
tftp server, though sometimes I do.
I'm using lan91c111 ether driver and following occours (compiled with 
either gcc-2.95.3 or gcc-3.2 toolchain)
uboot> boot
BOOTP broadcast 1
got BOOTP packet (src=67, dst=68, len=300 want_len=300)

Bootfile: kernel.img
Got good BOOTP

after len bad is reported transmission stalls for a while then 
continues. I also noticed that sometimes it copies kernel with only few 
len bad notices sometimes it timeouts. During stalls arp requests are sent:
arp who-has 10.10.10.2 tell 10.10.10.1
14:12:00.735751 arp reply 10.10.10.2 is-at 0:c4:e:43:36:68

no reply from lan91c111 ?

Anybody had similar issues ?
Where should I start debugging ? - ether driver smc91111.c seems like a 
good start.
What else am I looking for ?

Are you sure your hardware is ok? I've seen similar things on hardware
which works only "sometimes". 

In general, the SMC91111 driver works on several boards here (although I
havn't tested today's CVS).

I have flawlessly working u-boot.bin (I didn't compile it myself) image 
from 1.0.0 version on the same hardware, but I can't seem to reproduce 
the same image from the 1.0.0 sources , plus I was told that I should be 
using latest CVS version of u-boot.

I'm not using that image cause it has disabled command line passing to 
kernel so I can't boot over NFS.

My board is similar to Trizeps II, pxa255 cpu with 64M  ram and 32M flash.

do you have a 

#define __LITTLE_ENDIAN

in your config?

no, it's not defined in any of my sources in include/configs/board.h nor 
in board/board.c.

Should I put it somewhere ? It was not defined in configuration for 
1.0.0 version of u-boot.

how did you get the working 1.0.0 u-boot?  i thought you said you have
been unable to recreate a valid 1.0.0 base, or a cvs base, or <foo> ?

if your platform is LE, you need the define.  the PXA/XScale series 
can be either, it's just a bit set in the processor.

i got it on cd as already compiled bin image, along with the source that 
some third person previously worked on. bin image created date is 
supposed to be compiled from the sources provided. we are both even 
using the same toolchains.
i'm unable to recreate 'working' image (as the one i got on the cd) from 
the sources provided which are dated at 15.12.03 (as uboot 1.0.0 version).
