Linux Boot to Monitor not to Console

[PaulDeMetrotion]

Need help getting local video to work on a Linux kernel.

I have built a Linux 3.0.35 kernel for a custom SBC in development. The kernel boots fine on the console display. I am able to log on as the root and perform basic Linux commands. This is great, but I want to have the Linux display on one of the local monitors and use a local keyboard to control the kernel. How do I redirect the Linux display to a supported monitor? I assume I should be able to see video on the console and the selected monitor simultaneously.

I tried to remove the 'console=' command line argument in u-boot and this almost worked. This did redirect the video to my desired monitor but the boot stops and the file system does not mount.

Here is the bottom of the monitor output. I have noted where the boot process stops when I disable the console.

SOLVED: Found that the code in rc_mxc.S was going into a sleep mode if no console was attached. Changed the else statement to use my video source instead and everything worked fine!!!

Nobody has any ideas???

Not sure if this is what you want, but you can leave the console as it is and connect to the board through a SSH connection. On the SSH session, run any command you want and on the serial console, monitor your kernel messages.
