[Buildroot] Kernel does not boot : dts is not appended to the kernel (Karo TX53 [imx53])

[Sagaert Johan]

Hi all

I am trying to build the Kernel from within buildroot but fails starting.

When I build the kernel from the commandline en append the dts file then it works :

This is giving me a working kernel:

#The DT configuration data needs to be converted to a binary blob and
#appended to the kernel zImage:
#1. Compile the kernel (including modules and DT data):
make ARCH=arm CROSS_COMPILE=arm-linux- zImage dtbs modules

#2. Concatenate the kernel with the generated DT blob:
cat arch/arm/boot/zImage arch/arm/boot/tx53.dtb > arch/arm/boot/zImage_tx53

When I look under output/images I see only zImage, not the kernel with the appended dts blob (zImge_tx53).
So is there something I am overlooking ?
