Mu current setup fails to build it :( (1) I've been following the steps outlined here: http://www.yoctoproject.org/docs/bsp-guide/bsp-guide.html (2) I'm tracking the bernard branch of poky. (3) My new meta directory (meta-tephra) is inside the top-level of my poky checkout. Here's what's in there (find): ./recipes-kernel ./recipes-kernel/linux ./recipes-kernel/linux/linux-yocto-stable_git.bbappend ./recipes-kernel/linux/linux-yocto-stable ./recipes-kernel/linux/linux-yocto-stable/defconfig ./conf ./conf/machine ./conf/machine/tephra.conf ./conf/layer.conf ./images ./images/poky-image-tephra-sdk.bb (4) Contents of tephra.conf TARGET_ARCH = "arm" MACHINE_FEATURES = "kernel26" IMAGE_FSTYPES ?= "tar.bz2 ext3" ROOT_FLASH_SIZE = "280" IMAGE_ROOTFS_SIZE_ext2 ?= "280000" IMAGE_ROOTFS_SIZE_ext3 ?= "280000" # Don't include kernels in standard images RDEPENDS_kernel-base = "" PREFERRED_PROVIDER_virtual/kernel ?= "linux-yocto-stable" #PREFERRED_PROVIDER_linux-libc-headers ?= "linux-libc-headers-yocto" EXTRA_IMAGEDEPENDS += "" MACHINE_ESSENTIAL_EXTRA_RDEPENDS = "" require conf/machine/include/tune-arm1136jf-s.inc KERNEL_IMAGETYPE = "uImage" SERIAL_CONSOLE = "115200 ttyS0" (5) Contents of linux-yocto-stable_git.bbappend FILESEXTRAPATHS := "${THISDIR}/${PN}" COMPATIBLE_MACHINE_tephra = "tephra" KMACHINE_tephra = "arm_versatile_926ejs" SRC_URI += "file://defconfig" (6) Contents of defconfig Same as mx3_defconfig (for freescale iMX 3) (6b) for completeness here's layer.conf # We have a conf directory, add to BBPATH BBPATH := "${BBPATH}:${LAYERDIR}" # We have a recipes directory containing .bb and .bbappend files, add to BBFILES BBFILES := "${BBFILES} \ ${LAYERDIR}/recipes*/*/*.bb \ ${LAYERDIR}/recipes*/*/*.bbappend \ ${LAYERDIR}/images/*.bb" BBFILE_COLLECTIONS += "tephra" BBFILE_PATTERN_tephra := "^${LAYERDIR}/" BBFILE_PRIORITY_tephra = "5" (7) Minor confusion - When I invoke bitbake virtual/kernel -DDDD -v The process warns during the start of kernel_do_compile() (from kernel.bbclass) that "Warning: make dep is unnecessary now." It's trying to build deps - fair enough, as the value of KERNEL_MAJOR_VERSION is 'None' because that information is taken from the kernel build output: oe_runmake include/linux/version.h CC="${KERNEL_CC}" LD="${KERNEL_LD}" but this won't generate include/generated/utsrelease.h which is where the kernel version now lives. Changing the line to generate this target ensures that utsrelease.h is built, but KERNEL_MAJOR_VERSION is still 'None'. I'm pretty confused by this and need help :) (8) Major problem - The copying of my defconfig into .config causes the kernel build to terminate with: linux is not clean, please run 'make mrproper' Commenting out the defconfig reference in my bbappend: #SRC_URI += "file://defconfig" allows the kernel build to complete, but obviously not with the configuration I was after :( Any insight into what I'm doing wrong (either philosophically or technically) would be awesome. Thanks in advance, Tim
