That part should have worked for you, though it will only have
support for the 10.1" Freescale display.

Why did you do this part? Was it because of this bit in the U-Boot
README?

Otavio, does the "mx6qsabrelite" configuration place U-Boot in
unformatted space?

I'm not seeing that a boot script is created in the machine layer:

If the image does what I think it does, and has unformatted
space before the first formatted partition, you may be able
to do this by hand like so:

	sudo dd if=u-boot.imx of=/dev/mysdcard bs=512 seek=2

If that's the case, you can use the imx_usb tool described here
to at least load U-Boot over the USB link

There's no NAND on the board. Only SPI-NOR.

Sorry for the confusion here. It seems that some piece of
documentation went missing.

In general, we're recommending the use of the nitrogen6x
machine, even for SABRE Lite as discussed in a separate
thread yesterday.
