IIRC the usual way was to add kernel-devicetree package and let u-boot pick the proper dtb during boot. As for IMAGE_BOOT_FILES, you can tell wic to automatically rename files by passing the desired name after a semicolon like this: IMAGE_BOOT_FILES = "zImage zImage-imx6ul-14x14-evk.dtb;mx6ul-14x14-evk.dtb" -- Maciej Borzęcki Senior Software Engineer at Open-RnD Sp. z o.o. www.open-rnd.pl, Facebook, Twitter -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
