Re: [Ltib] Warning: unable to open an initial console

[Stuart Hughes]

Hi Vijay,

It's hard to tell what's happened.  All you can say is that there's
something wrong with the root filesystem.  One thing that can cause this
is missing device nodes (/dev/console).  Make sure you have these.

Maybe you could boot NFS and then mount the NAND rootfs.  You can then
take a look.  If that seems okay, try to chroot to it.

Is this the default configuration for this BSP? maybe it's worth trying
Freescale support.  I don't have this board, nor have I tried a NAND
Flash boot, so I'm afraid I can't help that much here.

Regards, Stuart
