Hi John,
 
What is the error that XMD
reports during download?  Could you do a cut/paste of the xmd 
console commands and error?
 Have you run a full memory test on the AFX SDRAM?
 
Hyperterminal is unfortunately
a very poor terminal IMHO, scrolling up does not work properly, 
and has caused many headaches
us in the past.  In windows world I use the free Tera Term 
Pro - http://www.ayera.com/teraterm/.
 
The Uart lite does not currently
support hardware flow control as you mention, so set the 
terminal to “None” for flow
control.
 
Best regards
 
Kris

Hi,
I am using a very basic V2p7 AFX 456 board, from Xilinx. It doesnt't have
an ethernet port or flash, so I usually remove those too. I leave the gpio
in, as there are 8 on-board LED's. And 8mb of SDRAM, where i download the
image.bin. It looks like I do everything the same as you!

One thing which is curiouis is sometimes the XMD console will report EDK
Error -  when the kernel is trying to boot. This leads me to beleive
the MB is trying to write something to the XMD console...by any chance
is it possible the system starting up is trying to use the XMD uart as
the console after boot?

Regarding hyperterminal - if you scroll up more than one page, it always
mangles the "history" of what it displayed. I don't know why!
Also, I dont think xon/xof should be used, as I beleive the uartlite does
not support hardware flow-control...

Cheers,
John

John, 
Suprisingly I did not do a whole lot.  I run an update on my kernel
and dist directories.  I then made sure my auto-make file was up to
date in the kernel architecture microblaze directory.  Once I had
this  I built the kernel with as little as possible.  I took
out the ethernet, flash, and gpio drivers.  I also changed the mdm
from the flash driver to the generic uclinx rom driver.  then I ran
the make dep and make and then booted thejimage.bin file through xmd.  My
commands I used where dow -data images/image 0x80000000 and then con 0x80000000.
 Simple as that.  But I am still having the issue that is will
nto let me login now.  So if it keeps doing this I may still go back
and try an older kernel download.  Also what board are you using?

Hi 
It seems like you got past the previous problem you were having, detailed
in the "booting uclinux" thread. How did you do this? I am still
"hanging" at the line

uclinux[mtd]: root filesystem index=0
VFS: Mounted root (romfs filesystem) readonly.
Freeing init memory: 32K


Can you help?

Cheers
John

When booting the uclinux on a memec v2p board I get the results below.
 But once it hits the login part I can not login.  I have tried
root as the username and pass and jsut root as used and no pass and I can
nto get it to login.  Also there is the one fail listed and not sure
if that is causing me a problem or not.  Also the only thing I changed
when I built the kerneal is I disable the ethernet and networking stuff
and the gpio driver and I also changed the MDM to the generic rom selection.
 All other option I left alone.
