Hi,everyone
I want to add uart port to kernel,so I need update patch
but I always get fail,when do bitbake -f compile linux-imx
my steps:
1.creating new Layer
fsl-community-bsp $ ./setup-environment build(my build folder)
sources $ yocto-layer create fsl-custom
*Edit and add the layer to the build/conf/bblayers.conf file
build $ bitbake-layers show-layers
2.patching the linux kernel
build $ cd tmp/work/imx6dlsabresd-poky-linux-gnueabi/linux-imx/4.1.15-r0/git
build $ # Edit any files you want to change(i change my imx6dl.dtsi to add uart port)
build $ git add /arch/arm/boot/dts/imx6dl.dtsi
build $ git commit -s -m uart
build $ git format-patch -1
3.create custom folder
sources $ cd meta-imx6
sources $ mkdir recipes-kernel
sources $ cd recipes-kernel
sources $ mkdir linux
sources $ cd linux
sources $ mkdir linux-imx-4.1.15
sources $ cd linux-imx-4.1.15
sources $ mkdir mx6
4.add patch
sources $ cat > meta-fsl-custom/recipes-kernel/linux/linux-imx_4.1.15.bbappend
FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}-${PV}:"
SRC_URI += "file://imx6/0001-uart.patch"
build $ cd tmp/work/imx6dlsabresd-poky-linux-gnueabi/linux-imx/4.1.15-r0/git
build $ cp 0001-uart.patch /.../linux-imx-4.1.15/mx6
fsl-community-bsp $ ./setup-environment build
build $ bitbake -c cleansstate linux-imx
build $ bitbake -f -c compile linux-imx (always fail )
build $ bitbake -c deploy linux-imx
thanks for help
