Yocto change psplash image without rebuild the system

I'm trying to change yocto splashscreen (generated by psplash) in a current built system, with no yocto rebuild process... Is there any possibility to change this image? I think I've to mount the boot partition that contains the start image and replace it...

Thanks a lot,

Solution

  • Yocto psplash recipe can be found here.

    As you can see, it uses an encoded image psplash-poky-img.h generated with help of this script then it compiles /usr/bin/psplash binary.

    If you want to patch your splash screen, you can use make-image-header.sh with your own image, then compile your own psplash binary with yocto SDK help, then replace psplash.

    Patching image is dependent to image type.

    Nevertheless, easiest way is to create a psplash_git.bbappend file, add your png image in files, and let magic appends:

    # Example of recipe-core/psplash/psplash_git.bbappend
# (insert my-custom-psplash.png image in recipe-core/psplash/files folder)

FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SPLASH_IMAGES = "file://my-custom-psplash.png;outsuffix=default"
