[meta-freescale] trying to boot a bitbaked image in various ways

Hi there,
thank you for the reply.
well, considering (2) below, I have already 'dd' the .sdcard image. but the boot fails. I think the 2009.08 uboot image looks for a couple of files in the root folder of the target fs. The questions is though, how does one use this u-boot.imx image that has been bitbaked?

as for (3), I understand this kernel will fail as  the hardware is missing. But then again why does yocto have a command to even extract and run the .tar.bz2 images "for use with nfs or qemu" ? 
how can I run the specific rootfs i bitbaked through the emulator?

Thank you once again for your help!

Hi there, I am trying to boot the image I created in several ways:
1) extracted the tar.bz2 image (with tar xjvf) and did an nfs boot directly from the sabrelite board ! This succeeded.

Good. 2)
 copied the .sdcard image to an microSD card and tried to boot locally 
from the microSD. This fails as the uboot version on the board is the 
one that sabrelite shipped with , (2009.08 i think). How do I go about 
updating the uboot (.imx file) that has generated from bitbake process?

You should 'dd' the .sdcard file to your microSD card. 
3) I started reading on yocto project and tried runqemu but it fails. Here is what I did:
        cd <yocto root>/sources/poky/
        . ./oe-init-build-env
        cd build #done automatically at exit from above script

 runqemu ../../../build/tmp/deply/images/uImage-blabla.bin 
../../../build/tmp/deply/images/fsl-image-test-blabla.ext3 ext3
 the qemu start running, 

The image built for SabreLITE won't be compatible with QEMU so it is expected to fail.
