Baud rate = 57600 8N1
Hardware Flow control = NO
Serial device = dev/ttyS0

Sorry, I did not do that. How do I turn on the network debug in redboot?
However, I get some message when I start the board after the redboot is
loaded.

I watched it. I watched through ethereal what are the packets that the
device is sending after installing redboot & restarting it.
It is sending nothing.
I am less into ethereal stuff. I just doubt, Is the ethereal capable of
capturing the bootp request patkets on the network. Just becos the
fields on the ethereal display are
Time Source destination xxx xx
& if the board is sending some BOOTP packets how will the ethereal
display them on the screen. I just doubt as there is no IP assigned yet
to the board we are using.
