Console on frame buffer for mpc823

From: Jan Damborsky <hidden>

  Hello,

I use custom board with MPC823 and TFT display
connected directly to TFT processor interface.
I would like to use display as console on framebuffer
when booting and running Linux.
I use Linux distribution from ElinOS (version 2.0),
kernel 2.4.3 running busybox on it.
I successfully compiled in kernel support for framebuffer on /dev/fb/0
(trying command ¨*dd if=/dev/urandom of=/dev/fb/0 count=100¨* is working
as expected)
but console always works on serial channel SMC1.
How to make kernel use console on /dev/fb/0 ?
I have attached output of *dmesg *command as well as
*.config* file.
                          Thanks in advance, HANYS

Good luck.

I have tried it, but without success.
I will try to upgrade kernel to newer
version.
                Thank you for your help.
