But I have not been lucky to solve my problem. May be I have old kernel version - 2.4.3. >>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. >> >> >... > > >>How to make kernel use console on /dev/fb/0 ? >> >> > >You have to configure the kernel to use the framebuffer as console >device.

When trying *cat /etc/group > /dev/tty*, it is send to serial line. Is it correct ? How to test that frame buffer is assigned to text console ? BTW: [1] CONFIG_SERIAL_CONSOLE is set - it is hardwired to CONFIG_8xx - may be it is problem - isn't it ? Thanks for help , HANYS ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
