Hi,
I have a question. How to add commands like "ubiattach" to /usr/bin of
rootfs image. I struggling with the recipes. I do not want to write my own recipe but I
need to edit some recipe and add the command. Which is the place? I am using yocto for my
project on TI platform and Linux.
Kindly help.
There is oe-pkgdata-util which can help to map files to recipes but we
do not have a database for mapping. Maybe it is a good thing to have
for your problem ubiattach is provided by mtd-utils-ubifs which is built
from mtd-utils recipe. I found it via above tool
% oe-pkgdata-util find-path /usr/sbin/ubiattach.mtd-utils
mtd-utils-ubifs: /usr/sbin/ubiattach.mtd-utils
% oe-pkgdata-util lookup-recipe mtd-utils-ubifs
mtd-utils
So you need to add
IMAGE_INSTALL_append = " mtd-utils-ubifs" in your image recipe or local.conf
Thanks,
Harish.

Hello team,
I want to remove some GPLv3 package from rootfs, but it is still present.
I am using INCOMPATIBLE_LICENSE = "GPL-3.0 LGPL-3.0 AGPL-3. 0"
still some package gnutls, libidn2, libassuan, are added into rootfs.

Hi there,
I am currently working on a minimal CLI only system.
The image is based on 'core-image-base' using sysvinit and busybox.
To reduce image size and boot time, I removed as many packages as possible. For
some application cases I will need python3 though.
My idea was to have python3 as some kind of add-on in a squashfs image, that
can be mounted only when needed.
So I tried to build an image only containing the python3 package, but as little
as possible otherwise, like this:
inherit image
IMAGE_FSTYPES = "squashfs-xz"
DEFAULT_TASK_PROVIDER = ""
DISTRO_EXTRA_RDEPENDS = ""
DISTRO_FEATURES = ""
POKY_DEFAULT_EXTRA_RDEPENDS = ""
IMAGE_FEATURES = ""
IMAGE_LINGUAS = ""
CORE_IMAGE_BASE_INSTALL = ""
RDEPENDS_${PN} = ""
PACKAGE_EXCLUDE = "busybox openssl run-postinsts update-rc.d"
VIRTUAL-RUNTIME_dev_manager = ""
VIRTUAL-RUNTIME_login_manager = ""
VIRTUAL-RUNTIME_init_manager = ""
VIRTUAL-RUNTIME_initscripts = ""
VIRTUAL-RUNTIME_keymaps = ""
VIRTUAL-RUNTIME_base-utils = ""
PREFERRED_PROVIDER_virtual/base-utils = ""
IMAGE_INSTALL = "python3"
But like this I can only manually exclude packages I already have in my main OS
image. Some packages can't be excluded at all, as python3 depends on them and
won't build if they are excluded.
Is there a way to have dependencies between images? So I could have the
python-image build know which dependencies are already built into my OS image
and therefore not include them itself?
Or would it be better to avoid building a second image and rather build
'python3' with my OS-image, adding it to PACKAGE_EXCLUDE and from within this
build process pack all python3 files into an image? If I were to pursue this
method, any suggestions on how to separate the python3 files from the rest of
my rootfs, including the necessary dependencies?
Any advice and idea is much appreciated.
Mit freundlichen Gr??en / Best regards
