How to include fitImage-initramfs in rootfs image

How to include fitImage-initramfs in rootfs image

[Richard Leitner]

Hi,
I'm currently facing issues on how to include a fitImage with 
devicetrees and a INITRAMFS_IMAGE in my rootfs image.

My config is something like:

KERNEL_IMAGETYPE = "fitImage"
KERNEL_CLASSES  = "kernel-fitimage"
KERNEL_DEVICETREE = "a.dtb b.dtb c.dtb"
INITRAMFS_IMAGE = "initramfs-mine"

To include the "normal" fitImage without the initramfs in the rootfs the 
following works:

IMAGE_INSTALL_append += " kernel-image"


When digging around a little bit I found that the 
fitImage-initramfs-mine is deployed to tmp/deploy/images but there's no 
package including that file.

Therefore I'm unable to include it via IMAGE_INSTALL.

Am I missing something?
Is anybody of you aware of a solution?
Does kernel-fitimage and kernel.bbclass offer this at all?

Any help would be greatly appreciated! Thanks!

regards;Richard.L

Ok. I saw how it's generated in the kernel-fitimage.bbclass and 
kernel.bbclass... But is there any "clean" way of adding it to my rootfs 
image like the fitImage?

fitImage-initramfs-mine is an image, so it is not in any package, it is
handled by kernel.bbclass, you can check it for more info.

I think that set both INITRAMFS_IMAGE and INITRAMFS_IMAGE_BUNDLE should work,
you have set INITRAMFS_IMAGE, so also set:

INITRAMFS_IMAGE_BUNDLE = "1"

That was also my first thought, but unfortunately this doesn't work. 
There's still one fitImage and one fitImage-initramfs-mine in the deploy 
dir and the one included in the rootfs image has the same checksum and 
size as the fitImage without the initramfs.

Try:

$ bitbake virtual/kernel -e >kernel.py

And check INITRAMFS_IMAGE_NAME in kernel.py, make sure it contains 
initramfs-mine, and try:

$ bitbake virtual/kernel <your image> -ccleansstate
$ bitbake <your image>

Both fitImage's get built and deployed in tmp/deploy/images/.

But in tmp/work/../<image>/1.0-r0/rootfs/boot/ there's only the fitImage 
without the initramfs.

Apart from the tmp/deploy dir I "find" the fitImage-initramfs also in:

tmp/work/../linux/.../deploy-linux/
and
tmp/work/../linux/.../deploy-linux/linux-standard-build/arch/arm/boot/

Any more ideas?

I'm n not sure bundling the initramfs with the kernel is the best approach
when using a fitImage. After all, the purpose of the FIT is to describe to
U-Boot the individual components and their location already.

I usually just add the fitImage manually in a ROOTFS_POSTINSTALL_COMMAND,
either via a specific project's bbclass that all actual images inherit, or
directly in the actual image recipe.

The INITRAMFS_IMAGE_NAME is set correctly.

Nonetheless unfortunately the image still includes the fitImage without 
initramfs... Any further ideas?
