I pulled a default Arago/yocto image to build using bitbake and the output image is 8 GB. I need to reduce the size ot be less than 4 GB, so I tried to remove the meta-ros layer. I am getting an error, but cannot determine the source of the error:
ERROR: Nothing RPROVIDES 'packagegroup-ros-ti' (but /opt/PHYTEC_BSPs/yocto_ti/sources/meta-arago/meta-arago-distro/recipes-core/images/tisdk-rootfs-image.bb RDEPENDS on or otherwise requires it)
(yes, that is the whole error message and seems very grammatically incorrect and I got confused when I re-read it...)
Then tisdk-rootfs-image.bb says nothing about ROS and I can't find (grep -r ros) where ros is required.
How can I figure this out or what depends on ROS.
Bonus points for figuring out other things I can remove (I need GStreamer, but I don't think that I need qt5. Also I don't need any examples, samples, demos, etc).
How about building your own image up, instead of starting from a large image and trying to cut bits out? Much easier to build up than down.
