Is it possible to acces single bb file for two machine configurations ?in yocto setup?

[veeranjaneyulug]

Hi all,

we are using yocto setup.But we one doubt is it possible to access two machine configurations from single u-boot source bb file ?

machine1 and machine2 configure in sources/meta-fsl-bsp-release/imx/meta-fsl-arm/conf/machine/machine1.conf

like that i gave two machine configurations but i added both machine related patches in u-boot source bb file.

But with out commenting both patch files how can I access one machine patch file in bb file .in bb file

$ vi sources/meta-fsl-bsp-release/imx/meta-fsl-arm/recipes-bsp/u-boot/u-boot-imx_2014.04.bb

From above bb file is it possible to access two different machine configurations by setting machine name

we added the below two lines in above u-boot bb file .

do_patch_prepend(){

if [ "$MACHINE" = "imx6_zcam" ]; then

        SRC_URI +="file://0001-imx6_zcam_uboot_customization.patch"

elif [ "$MACHINE" = "imx6_zcam_custom" ]; then

        SRC_URI +="file://0002-imx6_zcam_custom_uboot_customization.patch"

else

        echo""

fi

}

Then export build directory

$source setenvironment -b build

$vi conf/local.conf

In the above file we gave MACHINE ??=machine1   selected

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

Then extract u-boot source

$bitbake u-boot -c unapck -f

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

Then apply patch

$bitbake u-boot -c patch -f

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

But patch was not applied .so any body have any idea of that .

$bitbake u-boot -c compile/build -f

i gave its not compiling giving patch was not extract .

Thanks & Regards

Hi,

try this

do_pre_configure() {

    patch -p1 < ${WORKDIR}/<your patchfile name>

}

add the task pre_configure before do_configure, but after after do_patch, also dont give .patch extension to patch file

Hi Pranav Madhu

Thanks for your reply reply.

But i tried no use .its not extracting .I gave normal syntax patch added like SRC_URI+=<"file://patchname">.Its working but i want gave two patch files at the same time  for different machine configuration patch files.Is it possible to give ?

Thanks & Regards

Hi Veeranjaneyulu,

Sorry I'm not sure about it, try to give the do_pre_configure in if-else condition.

[veeranjaneyulug]

Its ok pranav .

Any way thanks for your reply.

Hello Veeranjaneyulu,

It should be theoretically possible to do this, although I haven’t personally tired it. It seems odd that you’re not seeing the patch being applied. Have you tried using MACHINE ??=’machine1‘ on the configuration file and then performing a clean to the recipe to force it to build it from scratch? It may be possible that Bitbake already has the file so does not need to run the tasks again.

Please let us know of your findings!

Hello Veeranjaneyulu,

On a second thought, I think the syntax should be like the following to use the value of MACHINE on the logic argument of the function. Perhaps this may help.

if [ "${MACHINE}" = "imx6_zcam" ]; then

        SRC_URI +="file://0001-imx6_zcam_uboot_customization.patch"

elif [ "${MACHINE}" = "imx6_zcam_custom" ]; then

        SRC_URI +="file://0002-imx6_zcam_custom_uboot_customization.patch"

Thanks for your reply.

I tried like that syntax also but patch was not extracted ,it means in source directory we cant able to get patch related extracted source .Thats we got custom config error issue.

Then compile by using bitbake .Its giving below error .ie reason patch extracting issue.I gave individual buildings .Those builds are compiling and building.

Hi @veeranjaneyulug did you resolve your issue? I am stuck at the same point. I want to apply same patch for 2 different machines in single .bbappend file
