imx6 kernel patching error

riteshpanchal — Thu, 25 Jun 2015 06:53:09 GMT

i am using imx6qsabresd board.

I am lerning kernel patching using yocto.

for testing i changed 'build-x11/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.14.28-r0/git/drivers/media/platform/mxc/capture/ov5640.c' file.

i followed below link for creating the patch.

https://community.freescale.com/docs/DOC-95252

and then i created custom layer using

yocto-layer create fsl-custom

in source directory.

PFA layer folder with .bbappend and patch file.

I also added new BBLAYER info in conf/bblayers.conf.

And then if i try to execute following command

bitbake -c cleansstate linux-imx

i got following error

ERROR: No recipes available for:
/home/ritesh/fsl-release-bsp/sources/meta-fsl-custom/recipes-kernel/linux/linux-imx-3.14.28.bbappend

Please suggest any solution

The steps overall look fine.

Have you checked that your layer is being parsed by bitbake using the following command?

$ bitbake-layers show-layers

If the layer is showing next I would recommend making sure that the append file is being picked up. Please run:

$ bitbake-layers show-appends

Is the append showing?

Please find the output of show-layers and show-appends

No append is not showing.

But if i add contain of my .bbappend that is

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:"
SRC_URI += "file://0001-Test1.patch"

in sources/meta-fsl-bsp-release/imx/meta-fsl-arm/recipes-kernel/linux/linux-imx_3.14.28.bb i can able to successfully patch kernel.

And the other method is that after modifying the source file i executed following command

bitbake linux-imx -c compile -f
bitbake linux-imx -c deploy

and pasted modified .ko module in rootfs partition of my sdcard. This works for testing purpose.

But i want to do that step using patching.

Hello Ritesh Panchal,

I'm glad you made it work with a workaround.

The problem seems weird since your layer is being parsed. I believe the problem might be that the linux-imx_3.14.28.bb recipe moved away from the regular naming convention of using dashes trough the name and is using an underscore now.

So you usually did had the linux-imx-3.14.28.bbappend format but now the recipe seems to be named linux-imx_3.14.28.bb, causing a mismatch if you stick to the regular naming convention.

linux-imx-3.14.28.bbappend

linux-imx_3.14.28.bb
