Hello list,
I have trouble getting a FIT-image to work on my lite5200-evalboard.
Everything seems to be fine until I want to boot:
"ERROR: Not a FDT image - must RESET the board to recover."
Here's what I'm doing:
1.) compile u-boot 1.3.4 for lite5200 with fit support:
--- 1/include/configs/IceCube.h 2008-08-12 16:08:38.000000000 +0200
+++ 2/include/configs/IceCube.h 2008-09-29 11:26:26.000000000 +0200

#define CFG_MPC5XXX_CLKIN 33000000 /* ... running at 33.000000MHz */
#define BOOTFLAG_COLD 0x01 /* Normal Power-On: Boot from FLASH */
2.) create a kernel image (2.6.25) vmlinux.bin.gz (4MB with
root-filesystem in initramfs)
3.) create a flat device tree blob (using dtc 1.2.0):
dtc -b 0 -V 17 -R 4 -S 0x3000 -I dts -O dtb -f devicetree.dts > target.dtb
4.) create an FIT-image from fdt-blob and kernel with default example
its-file from doc-directory:
mkimage -f kernel_fdt.its kernel_fdt.itb
5.) check, if image-file is valid:
./tools/mkimage -l kernel_fdt.itb

As you can see the image-type of the fdt changed from "Flat Device
Tree" to "Unknown Image" after decompressing the kernel, but the hash
integrity seems to be fine (?!)
What am I doing wrong? What's missing?
greets
Simon
