Hi Flavio,

I have a client side package at my layer, you could check it at:

http://github.com/veter-team/veterlayer/tree/master/recipes/xenomai

It's pretty strait forward. Kernel is different story, I've just made
a patch to customized kernel:

Hope this helps,
Maksym.

Adding I-pipe and Xenomai as a single patch to the kernel does not seem
the way to go.

I would rather have the linux kernel building rules call
prepare-kernel.sh to apply the I-pipe patch and setup xenomai links to
the xenomai package source directory. It is not really hard, and it
makes things way easier to maintain.

It was just a quick way to get result, when I have time I'll try to
rework recipe with your suggestions.

No problem, really, it was just a remark.

Hi
I am OE developer and looks like there is any Xenomai recipe inside it.
BTW which platform are you using?

You mean "there is not any" ? or "there is a" ?

Anyway, using a search engine yields the following URLs:

Hello,

Thank you for your quick response (despite my delayed answer).

I used the separated kernel approach too (delivery time issues). I
intend to reorganize in order to have the complete procedure, such as
recommended by Gilles. When I get it done, I'll send here the patch.

I'm using imx53 quick start board for my project, using meta-fsl-arm
with Yocto project.

Thank you very much for your help.

Best regards,

Flavio

PS: I couldn't find a Xenomai recipe in Openembedded tree.

Sorry,
I meant there is not any Xenomai recipe inside OE.

Hi,

I'm just working on it. I'm newbie in Yocto, but those recipes seem to be working to me.
I use Freescale Linux SDK (based on Yocto) for QorIQ processors. 

Recipe for building kernel:

#-------------------------------------------------------------------------------

inherit kernel
require recipes-kernel/linux/linux-dtb.inc

DESCRIPTION = "Linux kernel 3.2.21 patched by Xenomai 2.6.1"
SECTION = "kernel"
LICENSE = "GPLv2"
DEPENDS = "xenomai-libs-2.6.1"

WW_KERNEL_VER = 3.2.21
WW_XENOMAI_VER = 2.6.1

S = ${WORKDIR}/linux-${WW_KERNEL_VER}

LIC_FILES_CHKSUM = "file://${WORKDIR}/linux-${WW_KERNEL_VER}/COPYING;md5=d7810fab7487fb0aad327b76f1be7cd7"

# require recipes-kernel/xenomai/linux-xenomai-${PV}.inc

SRC_URI = "http://www.kernel.org/pub/linux/kernel/v3.x/linux-${WW_KERNEL_VER}.tar.bz2 \
		http://download.gna.org/xenomai/stable/xenomai-${WW_XENOMAI_VER}.tar.bz2 \
		file://missing-ipipe-include-in-gpio-mpc8xxx.c.patch	\   
	"

# Find the kernel config file in the right directory.
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:"

# Name of the Woodward kernel configuration file
WW_KERNEL_CFG_FILE := "config-${WW_KERNEL_VER}-ipipe"

# use this ww kernel configuration
SRC_URI += "file://${WW_KERNEL_CFG_FILE}"

# prevent the fsl-layer kernel_do_configure_prepend() from using the kernel defconfig,
#  our config should be used instead
KERNEL_DEFCONFIG = "${WORKDIR}/${WW_KERNEL_CFG_FILE}"

do_configure_prepend() {
	# copy desired defconfig so we pick it up for the real kernel_do_configure
	echo "Copying WW defconfig"	
	cp ${KERNEL_DEFCONFIG} ${B}/.config

	cd ${WORKDIR}/xenomai-${WW_XENOMAI_VER}
	./scripts/prepare-kernel.sh --arch=powerpc --linux=${WORKDIR}/linux-${WW_KERNEL_VER} --ipipe=${WORKDIR}/xenomai-${WW_XENOMAI_VER}/ksrc/arch/powerpc/patches/ipipe-core-${WW_KERNEL_VER}-powerpc-1.patch

	cd ${WORKDIR}/linux-${WW_KERNEL_VER}
}

require recipes-kernel/linux/linux-tools.inc
#-------------------------------------------------------------------------------

Xenomai libraries (xenomai-libs.bb):

#-------------------------------------------------------------------------------

	rm -rf ${D}/xenomai/share/doc/

# We enumerate all directories excluding /usr/xenomai/share/ (it contains only documentation which occupies about 33MB)
