But I am facing a new problem while using bitbake for the build process. I have checked to build the odroid kernel with a standard crosscompiler tool chain and it works without any problems. When I do the same with the bitbake toolchain (bitbake virtual/kernel), it somehow creates a recursive link in the folder package/usr/src/kernel/drivers/gpu/arm/mali400/ump/arch/arch-release -> arch-release This causes a crash in the build system. Compilation runs fine though. This error seems to be within do_package. I have removed the link, but somehow it is created automatically. Any ideas? /Markus On 09.07.2014 14:44, Bruce Ashfield wrote: > On 14-07-09 05:38 AM, Dr. Markus Eich wrote: >> 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"? > > To trigger the oe-core kernel processing to use the defconfig, you need > to put that defconfig in your SRC_URI. > > Which means you should grab a copy of that from the kernel tree, and > in the same directory structure as your kernel recipe. > > See meta-skeleton/recipes-kernel/linux/linux-yocto-custom.bb for an > example. > > Cheers, > > Bruce > > >> >> 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 >> >> >> >> > -- Dr.-Ing.
