Hello.
I have “altera-image-minimal” recipe which creates minimal rootfs based
on Linux kernel provided by “linux-altera-local” recipe. This kernel is
fetched from local directory.
After first time building “altera-image-minimal”, it produced rootfs
with modules version contained “-dirty” at the end. However kernel built
from sources in local directory doesn’t have “-dirty” in version string.
Thus kernel can’t run with produced rootfs.
I opened directory which contains Yocto’s copy of Linux sources
build/tmp/work/socfpga_socrates-poky-linux-gnueabi/linux-altera-local-1.0-r1/socrates_linux/
then run “make ARCH=arm kernelrelease” to investigate kernel version.
This command outputs the version with “-dirty”. I have found that
“-dirty” string is appended from script in kernel sources. That script
uses output from “git diff-index --name-only HEAD” to determine if
working directory is “dirty”. To find changed files, I ran same command,
it’s oddly but the output was empty. Then I rerun “make ARCH=arm
kernelrelease”. This time it prints the version without “-dirty”.
Does someone have any clue why it can be so?
My main question is: how can I recreate rootfs image starting from the
point after fetching Linux sources, so Yocto’s copy will remain intact?
I spent lot of time trying to figure it out by myself with no luck. My
idea was to find sequence of commands used to create image and run only
commands after fetching kernel sources. Unfortunately I didn’t manage to
find the sequence anywhere. How such things need to be solved in Yocto?
Can you please try this and share if it works for you:
bitbake -c cleanall dirtypackage myimage
bitbake myimage
Regards,
Nikolay
