[yocto] EXT SENDER - yocto Digest, Vol 104, Issue 95

[Tg, Harish]

Hi Paul,
               I understood what you are trying to say but from where does the Yocto pick up the contents for a directory in final rootfs image. Is there any recipe file in which I can find this. For example: do_install() etc.
I also came to know from you that I need a recipe for adding a file into rootfs image. That's well understood. Please clarify about the particular recipe file where the contents are copied from source to the rootfs image.

Thank you for writing to me.

Regards,
Harish.

In a Yocto Project build, the rootfs is built from packages and the packages are in turn built from recipes. The supported process for adding new software to the image is to write a recipe which creates a new package, then add the package to IMAGE_INSTALL for an image.

There isn't a location where you can just drop files for them to be included in a rootfs build.

I'd recommend you search online for a tutorial on this, there's plenty of good resources available.
