uImage for ls1012frdm?

Trying to generate uImage for ls1012frdm board to boot from network.


I built yocto sdk 2.0 for Qoriq using ls1012afrdm as machine, all builds fine, but I do not get uImage file, only Image file.

In the instructions for Qoriq SDK to boot tftp and nfs mount, you need uImage file:


Section in QorIQ-SDK-2.0-1703-IC-Rev0.pdf:

4. Booting up the System
TFTP the kernel image to the board, then boot it up.
=>tftp 1000000 <uImage name>
=>tftp c00000 <platform dtb name>
=>bootm 1000000 - c00000
Now the board will boot up with NFS filesystem.


So I tried modifying local.conf with this:



Then tested with this:

bitbake -e fsl-image-core | egrep ^"KERNEL_IMAGETYPE"


But still get image type as Image, not uImage. So I modifed this file:


to add this:



Then tested with this:

bitbake -e fsl-image-core | egrep ^"KERNEL_IMAGETYPE"

And now I get image type as uImage, so I built "bitbake virtual/kernel" and get this error:

How can I get uImage to boot from the network? ( uboot is using bootm )
