[OE-core] Failed to build zImage-initramfs

[JH]

Hi,

Apologize if it is not right mailing list for helps, please advise
which mailing list I should go.

I have been trying to build zImage-initramfs, according to the
oe-core/meta/classes/kernel.bbclass, I defined following variables in
local.conf:

INITRAMFS_IMAGE = "zImage-initramfs"
INITRAMFS_IMAGE_NAME = "zImage-initramfs"
INITRAMFS_IMAGE_BUNDLE = "1"
IMAGE_INSTALL_append = "zImage-initramfs"

But I had following errors:

ERROR: Nothing RPROVIDES 'zImage-initramfs' (but
/build/Ramdisk/oe-core/../meta-solar/recipes-core/images/ram-image.bb
RDEPENDS on or otherwise requires it)

NOTE: Runtime target 'zImage-initramfs' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['zImage-initramfs']

ERROR: Required build target 'solar-image' has no buildable providers.
Missing or unbuildable dependency chain was: ['ram-image', 'zImage-initramfs']

In my ram-image.bb:

inherit core-image

IMAGE_ROOTFS_SIZE = "100000"
IMAGE_FSTYPES += " ${INITRAMFS_FSTYPES} cpio.gz tar.gz"
PACKAGE_INSTALL = "${IMAGE_INSTALL}"

What I am missing for "Nothing RPROVIDES" error?

Thank you.

Kind regards,
