Hi,=0A=
=0A=
I'm trying to create a image recipe based on a existing one.=0A=
I've searched online, and I could find such an example.=0A=
=0A=
My problem is that the image I what to serve as a base is changed in=0A=
another layer, and I want to include that changes.=0A=
=0A=
Ex:=0A=
=0A=
(tree)=0A=
=0A=
Prj_root=0A=
    -> layer1=0A=
        -> recipes-core=0A=
            -> images=0A=
                -> my-image.bb  [This is the base recipe]=0A=
    -> layer2=0A=
        -> recipes-core=0A=
            -> images=0A=
                -> my-image.bbappend [This is the changed one]=0A=
    -> layer3=0A=
        -> recipes-core=0A=
            -> images=0A=
                -> my-image-dev.bb [this is the new image, based on my-imag=
e]=0A=
=0A=
my-image.bbappend is something like this:=0A=
=0A=
--------------------- my-image.bbappend ---------=0A=
PROVIDES =3D "product"=0A=
=0A=
IMAGE_INSTALL +=3D " \=0A=
        <some_packages> \=0A=
"=0A=
IMAGE_INSTALL_remove +=3D " \=0A=
        <other-packeges>=0A=
"=0A=
=0A=
(+ other functions related with signing the image)=0A=
_________________________________________________=0A=
=0A=
The final image is created with 'bitbake product'.=0A=
And, I want to create a dev image that must be based on the current=0A=
"product" image (my-image.bb + my-image.bbappend) with some dev=0A=
packages.=0A=
So, I need to include the changes that my-image.bbapend does to this=0A=
dev image I'm trying to create.=0A=
=0A=
=0A=
Tried simple create a new image that should be a copy of the working=0A=
one, and then add the needed packages for development.=0A=
So I did the following...=0A=
=0A=
---------------- my-image-dev.bbappend ----------=0A=
=0A=
SUMMARY =3D "dev Image"=0A=
=0A=
require layer1/recipes-core/images/my-image.bb=0A=
------------------------------------------------=0A=
=0A=
I can run 'bitbake my-image-dev' and it runs, but doesn't produce the=0A=
same output as 'bitbake product'.=0A=
=0A=
Also, If I run 'bitbake my-image-dev' 1st, it finishes fine. Running=0A=
'bitbake product' after makes a bunch of other tasks and finishes fine.=0A=
Running again 'bitbake my-image-dev' finishes with an error on a=0A=
specific task. ( It shows that they are not building the same thing)=0A=
=0A=
How can I do what I need?=0A=
NOTE: I can't change anything in the layer1 and layer2.=0A=
=0A=
PS. Also tried to require the bbappend file, but bitbake fails saying=0A=
that it's not a bitbake file.=0A=
=0A=
Thanks in advanced.=0A=
