have you add one line for your dtb in the makefile?

Hello veeranjaneyulu g,

The 'compile' task builds only the zImage while the 'build' task will perform all the tasks for that specific recipe, 'linux-imx' in your case, which includes generating the dtb. So, Your dts is causing this build error. It looks like 'make' is not able to find the dts file "imx6_zcam_custom.dts" in the arch/arm/boot/dts/ directory. Could you confirm that this file is present in the source or not?

Regards,

Shubham
