The image artifacts can then be subsequently assembled by an external tool such as wic to create an actual image. This eliminates redundant image creation when using such tools. --- .../images/core-image-tiny-initramfs.bb | 31 ++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 meta/recipes-core/images/core-image-tiny-initramfs.bb diff --git a/meta/recipes-core/images/core-image-tiny-initramfs.bb b/meta/recipes-core/images/core-image-tiny-initramfs.bb new file mode 100644 index 0000000..216f3e0 --- /dev/null +++ b/meta/recipes-core/images/core-image-tiny-initramfs.bb @@ -0,0 +1,31 @@ +# Simple initramfs image artifact generation for tiny images. +DESCRIPTION = "Tiny image capable of booting a device.
