Thank you Sathish for the quick answer.
The recipes now copies odroidxu_ubuntu_defconfig to defconfig in the
workdir, but it still seems to be ignored.
Maybe I am missing some includes to make the .config from defconfig?
Using "make odroidxu_ubuntu_defconfig" using cross compiling (followed
by "make zImage") works fine, while bitbake virtual/kernel produces some
errors which are probably due to the wrong .config.
Cheers,
Markus

Hi Markus,
Try adding the following to your recipe file
KERNEL_DEFCONFIG = "odroidxu_ubuntu_defconfig"
do_configure_prepend() {
install -m 0644 ${S}/arch/${ARCH}/configs/${KERNEL_DEFCONFIG}
${WORKDIR}/defconfig || die "No default configuration for ${MACHINE} /
${KERNEL_DEFCONFIG} available."
}

Subject: [yocto] How to select defconfig for kernel build with yocto/bitbake
Dear all,
I work on the process to compile odroid xu kernel with yocto/bitbake
In the kernel sources (from hardkernel) I have the corresponding
defconfig file, i.e. in the git folder
/arch/arm/configs/odroidxu_ubuntu_defconfig.
How can I tell bitbake in my recipe to use "odroidxu_ubuntu_defconfig"?
My recipe looks as follow:
===
require recipes-kernel/linux/linux-yocto.inc
KERNEL_IMAGETYPE = "uImage"
COMPATIBLE_MACHINE = "odroid-xu"
LINUX_VERSION = "3.4.91"
LINUX_VERSION_EXTENSION = "-custom"
FILESEXTRAPATHS_prepend := "${THISDIR}/linux-hardkernel-3.4:"
S = "${WORKDIR}/git"
# from where to fetch the kernel
KERNEL_REPO_OWNER ??= "hardkernel"
KERNEL_REPO_URI ??= "git://github.com/${KERNEL_REPO_OWNER}/linux.git"
KBRANCH = "odroidxu-3.4.y"
SRCREV = "${AUTOREV}"
KV = "3.4.91"
PV = "${KV}+gitr${SRCPV}"
LOCALVERSION ?= ""
SRC_URI = " \
${KERNEL_REPO_URI};nocheckout=1;branch=${KBRANCH} \
"
PACKAGES =+ "kernel-headers"
FILES_kernel-headers = "${exec_prefix}/src/linux*"
===
Cheers,
Markus
