After the above message the device should be running kernel code. So,
you are going to need to add debugging output to the kernel.

Serial console is the easiest way. But barring that, I've used irda,
written pixels to the fb, and used the vibrator as debugging aids.

When one compiles a kernel it is built with a specific list of mtypes
that it supports. You need to make sure haret uses an MTYPE that the
kernel recognizes. Otherwise, the kernel will just silently hang on
boot.

What is the cpu type? Omap, samsung, other?
