>From below it looks like u-boot finds the kernel in the FIT, but your ramdisk is "corrupt". The error above suggests something is missing from the FIT. Can you check the initrd/ramdisk node in your FIT to make sure it is present and uses all the correct options and paths with respect to the initrd you intended to package?

Might also be helpful to provide the content of the .its file.
