The FIT file in yocto Thud (and actually Morty up) is generated by inheriting the kernel-itbimage.bbclass. This FIT image only includes the kernel and device tree (from what I can see). The FIT file from qoriq_sdk_v2.0 is generated by the fsl-image-kernelitb.bb recipe, which contains a kernel, device tree and rootfs. I have tried to move the fsl-image-kernelitb.bb recipe over to yocto Thud, but this recipe had errors building an image and seemed incompatible. Given the differences, is the FIT file from yocto Thud a file that can be used to boot the ls2088ardb? If the Thud FIT file can be used, what is the best way to load a rootfs to the system (say the hard drive) and get it to boot?
