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 4.4.1.9.3 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:

KERNEL_IMAGETYPE = "uImage"

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:

./meta-nxp-npi-1703/conf/machine/ls1012afrdm.conf

to add this:

KERNEL_IMAGETYPE = "uImage"

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:

Log data follows:

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

Look at the Section 11.2.5.6.7 of NXP SDK 2.0-1703 documentation:

https://www.nxp.com/docs/en/supporting-information/QORIQ-SDK-2.0-IC-REV0.pdf

Use mkimage for uImage creation.

Have a great day,
