Hi all, Considering the last commit by now dd8157136f63a665b3002ab99d2fe16db117d9fc then this files includes a debian directory grep file:// isar/meta/recipes-kernel/linux/linux-custom.inc SRC_URI += "file://debian" I created my own layer with a kernel recipe with my files/debian folder because I want some changes and then I tried - cleaning everything sensible - but just the isar debian dir is copied in place. Thus, I moved the isar debian folder mv isar/meta/recipes-kernel/linux/files/debian isar/meta/recipes-kernel/linux/files/debian.bak Then I cleaned and tried to build. This time, the correct debian folder has been copied in place. I think this is a bug and I wish to receive some help to fix it. Here following the recipe require recipes-kernel/linux/linux-custom.inc KBUILD_DEPENDS += " dwarves" KERNEL_DEFCONFIG = "debian-amd64-rt-defconfig" SRC_URI += " https://git.kernel.org/pub/scm/linux/kernel/git/cip/linux-cip.git/snapshot/linux-cip-${PV}.tar.gz " SRC_URI[sha256sum] = "9a45929d91ebaddbf6a0ef29750775e33d3c3f56f42f0a9e95e77e5b4eba3c6e" SRC_URI += "file://${KERNEL_DEFCONFIG}" S = "${WORKDIR}/linux-cip-${PV}" Thanks, R.
