Hi Rudy,
Thank you for the basic file... I have a question here... The git
directory is already saved on my work pc. What is the necessity to
download it again? The reason behind my asking this question is, it is
secured and so password is required. So, in order to avoid confusion I
already downloaded it to a directory called
"/home/damarla/linux-skidata.git". So can I just write
SRC_URI = "dir://home/damarla/linux-skidata.git"
I think in the above way I can just simply remove the KSRC and KBRANCH
variables from the linux-skidata.bb <http://linux-skidata.bb> file. The
revision tag is also not required in this cases as we are using the
kernel provided by the company itself, I mean for the first basic build.
The example code that was posted, already does this. KSRC points to
a git repository on your local machine:
KSRC ?= "<path to>/linux-skidata.git"
And the protocol is set to "file" in the SRC_URI
SRC_URI = "git://${KSRC};protocol=file;branch=${KBRANCH};name=kernel \
file://defconfig"
There's nothing more that you need to do.
One more thing is the skidata-carrier_defconfig is already in the
directory git I mentioned above at
"/home/damarla/linux-skidata.git/arch/arm/configs/skidata-carrier_defconfig"
... When compiling the kernel how can we tell the build system to build
the kernel using that specific defconfig file?
Putting the defconfig on the SRC_URI is all that you have to do.
This information is also covered in the quickstart and development
guides .. have you had a look at them ? If you have a look, you'll
see that more options are available with linux-yocto based recipes
(custom or the ones part of oe-core), which will allow you some more
flexibility in handling modifications to the kernel.
Cheers,
Bruce
Thanks Rudy in advance,
Satya

Hi Satya,
You will first need a kernel recipe, let's call it linux-skidata.bb
<http://linux-skidata.bb>. It can look like this:
DESCRIPTION = "Skidata Linux Kernel"
SECTION = "kernel"
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "file://COPYING;md5=d7810fab7487fb0aad327b76f1be7cd7"
PV = "3.2"
inherit kernel
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:${THISDIR}/${PN}/patches:"
# GIT repository location
KSRC ?= "<path to>/linux-skidata.git"
# Branch to check out
KBRANCH ?= "<branch>"
# Revision tag or AUTOREV
SRCREV ?= "${AUTOREV}"
SRC_URI = "git://${KSRC};protocol=file;branch=${KBRANCH};name=kernel \
file://defconfig \
"
S = "${WORKDIR}/git"
You will need to provide a defconfig file next to your recipe
containing the kernel configuration settings. Your kernel GIT repo
may contain a .config that is good for your hardware. In that case
you do not need a defconfig but is still a good practice and will
allow you to easily change the settings.
Then you need to adjust your machine configuration file:
PREFERRED_PROVIDER_virtual/kernel ?= "linux-skidata"
PREFERRED_VERSION_skidata ?= "3.2%"
That should do it.

Yes I got an error message when I was building the kernel...
Actuallly I have a kernel git given by the company.... I
downloaded it and is in my work pc.. How can I tell the build
system to use that kernel?

Satya,
your machine configuration file looks ok as far as I can
tell. Did you get an error message when building the kernel?
Did you try to build just the kernel e.g. bitbake linux-yocto?

Hello Guys... I think uImage is important but it is not

the rootfs and uboot.bin. Is there any variable that has
