 What serial terminal do you use?
I had the same problem when I was using hyperterminal.
When I changed to SecureCRT, everything workds fine!

A quick question..

i have been to use succesfully bootloader kernel and
ramdisk , but
only on certain serial port speed .

I am facing a data corruption in dowloading
kernel+ramdisk image
at higher serial port speed.

if i set my baud speed to 19200 it WORKS FINE.

otherwise at higher serial port speed  the execve of
/bin/sh just
hangs and .

also this problem is related to cpu frequency when i
make that
lower or higher the behaviour changed
unpredicatabley.

somebody pointed for skew problem woth sdram at
higher cpu
frequency.

any body has more here to add...
