[yocto] How to select defconfig for kernel build with yocto/bitbake

[Sathish Kumar Balasubramaniam -ERS, HCL Tech]

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."
}


Regards,
B.Sathish Kumar

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
