[yocto] ask a question about filesystem in yocto
Dear all, I'm new learner and user of yocto. When I used it, I encountered a problem. I don't know how to resolve it, so I ask for help. the problem is how can I create a new partition on yocto? if I have a package named webui, it can be generate several execute files and configuration files, the execute files will be install into filesystem, such as "/usr/bin", and be packed to rofs. but I don't want pack the configuration files to rofs, and I want create a new image and the image will be a partition of the global image, and pack the configuration file to it, when the system start running, it can be separatemount to the filesystem. When pack to rofs image, I don't know how to separate the execute file and configuration file in the webui package and pack to different part. Can someone help me to tell me how to solve this problem? I am looking forward to your reply. thanks， Byron-- ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
[yocto] Adding dtb to machine.conf extending it
Hi all. I need to add my dtbo to overlays. I'm using RaspberryPI 3 with pyro and meta-raspberrypi I have to add tft35a.dtb to /boot/overlays in the file image. Can I extend raspberrypi3.conf? MZ -- ___ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto

You can and it will work, but modification of external layers is considered as a bad practice. You would rather want to override the given variable you need to modify in local.conf or in your custom layer.

Please take a look at wic:
https://www.yoctoproject.org/docs/2.4.2/dev-manual/dev-manual.html#creating-partitioned-images-using-wic
You can for example exclude some subdirectory from main rootfs partition
and place it onto another partition instead.
Take a look at following wic flags:
--rootfs-dir
--exclude-path
You can define subdirs to split in local.conf or another config file
(e.g. distro config) using the WIC_CREATE_EXTRA_ARGS
and flags as: --rootfs-dir rootfs-main=${IMAGE_ROOTFS}
I am looking forward to your reply.
thanks，
Byron
