Hi I've compared the configs and I cant find any difference that would affect the output.
What i've discovered is that when I dont append any "console=" to the Kernel command line the output says: <6>console [tty0] enabled And when I append: console=ttyS0,115200n8 this line doesn't appear. So I suspect that the output is directed to tty0 but I cant see that anywhere, the VGA display is blank and so is the serial console. Any ideas on what I've missed in the kernel config or what I can do to see the output on tty0?
