FIT Image with ramdisk

I have the following problem:

I have uImage + dtb + ramdisk

All it works if I boot in "standard mode" (U-BOOT)

bootargs= root=/dev/ram rw ramdisk_size=256000

fatload mmc 0:1 0x12000000 uImage

fatload mmc 0:1 ramdisk-image-imx6dl.ext3.gz.u-boot 0x20000000

fatload mmc 0:1 0x18000000 fdt.dtb
bootm 0x12000000 0x20000000 0x18000000

If I create a fit image the system is not able to load the ramdisk

my its is:

/dts-v1/;

/ {
description = "FIT image with single Linux kernel, FDT blob and Ramdisk";
#address-cells = <1>;

images {
kernel@1 {
description = "Kernel";
data = /incbin/("./vmlinux.bin.gz");
type = "kernel";
arch = "arm";
os = "linux";
compression = "gzip";
load = <0x10008000>;
entry = <0x10008000>;
hash@1 {
algo = "sha1";
};
signature@1 {
algo = "sha1,rsa2048";
key-name-hint = "eng";
};
};

fdt@1 {
description = "Device tree";
data = /incbin/("./fdt.dtb");
type = "flat_dt";
arch = "arm";
compression = "none";
hash@1 {
algo = "sha1";
};
signature@1 {
algo = "sha1,rsa2048";
key-name-hint = "eng";
};
};

ramdisk@1 {
description = "Ramdisk Image";
data = /incbin/("./ramdisk-image-imx6dl.ext3.gz.u-boot");
type = "ramdisk";
arch = "arm";
os = "linux";
compression = "gzip";
hash@1 {
algo = "sha1";

};
signature@1 {
algo = "sha1,rsa2048";
key-name-hint = "eng";
};
};
};

configurations {
default = "conf@1";
conf@1 {
description = "Boot Linux kernel, FDT blob and Ramdisk";
kernel = "kernel@1";
fdt = "fdt@1";
ramdisk = "ramdisk@1";
};
};
};

After boot the system crashed with the following message:

RAMDISK: Couldn't find valid RAM disk image starting at 0.

A Fit image without ramdisk works fine

Where am I wrong?
