Hi,
I am new to yocto, so I don't know if this is the right list.
This will work, we also have the [email protected] kernel
mailing list.
I tried to build a kernel for the MTX-1 platform that uses an AU1500
which is a MIPS32 based SoC.
After some work I got the standard kernel (3.8.4) used in poky 9 to work.
But I encountered some problems:
In poky-dylan-9.0.0/meta/recipes-kernel/linux/linux-yocto.inc the
builddir is set to
"${WORKDIR}/linux-${MACHINE}-${LINUX_KERNEL_TYPE}-build", but
KERNEL_EXTRA_ARGS does not contain O="${B}". How is the the out of
source build of the kernel meant to work?
Can you elaborate on this ? Are you actually seeing a problem, or
just wondering about the glue ? If it's the glue, kernel-yocto.bbclass
sets:
KBUILD_OUTPUT = "${B}"
For the desired source/binary split.
The task do_kernel_configme trashed my kernel config. This may be
because defconfig is copied to ${B}/.config and do_kernel_configme is
executed in ${S} and does not find .config.
Same question as above. This is basic functionality and kernel_configme
is aware of the source/binary split, and has been doing this since
yocto 0.9.
Can you define "trashed" ?
Is the intended behavior of the out of source build for the kernel
documented.
Everything should be in the kernel-dev manual and the other yocto
project documentation. There's not that much to document, since the
functionality has been unchanged for quite some time and works behind
the scenes for a linux-yocto* based build.
Cheers,
Bruce
BTW: The kernel works and boots the core-image-minimal with usb USB
Storage as rootfs.
Best regards
Michael
