[U-Boot] Booting a dt zImage kernel

[Fabio Estevam]

Hi,

I am able to successfully boot a zImage kernel with latest 2012.04
U-boot on mx28evk.

Now I want to boot a dt zImage version.

These are the steps I am doing:

make menuconfig and select [*] Support MXS platforms from device tree

make imx28-evk.dtb

make

cat arch/arm/boot/imx28-evk.dtb arch/arm/boot/zImage > arch/arm/boot/zImage_dtb

cp arch/arm/boot/zImage_dtb  /tftpboot/zImage

Then I get the following result:

U-Boot 2012.04-00001-ga1f2367-dirty (Apr 23 2012 - 10:01:52)

Bad Linux ARM zImage magic!

Any idea of why this is failing?

Thanks,
