[yocto] Bitbake: error in cachedpath.py

[Markus Eich]

Dear all,

I am setting up Yocto to compile my kernel for odroid xu. During the 
package phase of building the kernel, I get an error in cachedpath.py

================

====================

Seems that the path is to deep?

To track the error, I have attached my kernel.bb


==================
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}"

SRC_URI = " \
   ${KERNEL_REPO_URI};nocheckout=1;branch=${KBRANCH} \
file://defconfig \
"


Any ideas ?

Cheers,

Markus
