custom PPC405GPr board almost boots - one last step

[Jerry Walden]

Greetings:

Well I'm getting much further now.  Problem was I did not have ext2
filesystem in
my kernel configuration.  Now the initialization seems to complete and it
looks to
me like either a prompt is trying to print out, or some other type of text.
In any
case I am wonder when the boot gets as far as this one does, can or does
something
happen to the serial port?  Does it try to bring up a console on the serial
port
and somehow is getting confused?


Thanks

Jerry

Check the baud rate of ttyS0 in /etc/inittab

If you are booting with 9600, then you need to have
something like:

# Example how to put a getty on a serial line (for a terminal)
#
T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100
