when I try to use "loadb 0xa0008000" command to transfer kernel file to RAM
in lubbock,
then use Kermit protocol supported by HyperTerminal in Windows 2000 to send
the uImage file,
always timeout, why?
I can success transfer file using the same procedure with Armboot-1.1.0.

That's probably because of a bug I introduced  recently.  Please  try
applying this patch:
