Hi everyone,


I currently made the update from sumo to the latest zeus (5.4.24_2.1.0)  and I have some issues.

In my custom meta-layer I have a patch that was applying ok in u-boot with sumo but doesn't apply anymore with the latest zeus revision.

I need this patch in order to change the default fdt_file.

Basically the default fdt_file is imx7ulp-evkb.dtb but I need to use a custom dtb file named imx7ulp-evk-custom.dtb.

Is there any other file structure for zeus in the *.bbappend file that I should follow? Maybe I need to replace the SRC_URI with another key-word?

- If I provide a patch file that doesn't exist in the u-boot-imx_2018.03.bbappend file I get a warning when compiling (bitbake -f -c compile u-boot-imx) -> so the patch is read from disk when compiling
