Problem with overlayed recipes

Problem with overlayed recipes

[-- Attachment #1: Type: text/plain, Size: 2462 bytes --]

Hi all,

I am trying to to generate an image with PREEMPT_RT kernel for an intel-corei7-64 target machine.
I see that the meta-intel layer already has a couple of recipes for that in recipes-rt/images/core-image-rt.bb and core-image-rt-sdk.bb, so I add this layer.
I choose core-image-rt-sdk.bb since I would like to have the development tools too.
In my local.conf I set
PREFERRED_PROVIDER_virtual/kernel = "linux-intel-rt"
as requested by meta-intel/recipes-rt/images/core-image-rt-sdk.bb, and also
MACHINE ?= "intel-corei7-64"
After several hours of bitbake core-image-rt-sdk , I get a core-image-rt-sdk-intel-corei7-64.rootfs.wic with which I can boot my machine, where uname .-r says 6-1-59-rt16-intel-pk-preempt-rt.
Everything looks fine up to here.

Now I am trying to add a new layer of mine, where I will put some stuff I need on the target machine. For the moment, I only have a "hello world" program there, just to check.
So I have meta-mytest/conf/layer.conf with:

BBPATH .= ":${LAYERDIR}"
BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \
${LAYERDIR}/recipes-*/*/*.bbappend"
BBFILE_COLLECTIONS += "mytest"
BBFILE_PATTERN_mytest = "^${LAYERDIR}/"
BBFILE_PRIORITY_mytest = "6"
LAYERDEPENDS_mytest = "intel"
LAYERSERIES_COMPAT_mytest = "nanbield"

and meta-mytest/recipes-mytest/images/mytest-image.bb with:

require recipes-rt/images/core-image-rt-sdk.bb
DESCRIPTION="Just a test"
IMAGE_INSTALL += "simple-local"

where simple-local is the hello world program, having its own recipe.

When I try bitbake mytest-image I get

ERROR: Nothing PROVIDES 'mytest-image'
mytest-image was skipped: Set PREFERRED_PROVIDER_virtual/kernel to linux-yocto-rt to enable it

If I understand, the problem is that there are two overlayed recipes, poky/meta/recipes-rt/images/core-image-rt-sdk.bb and meta-intel/recipes-rt/images/core-image-rt-sdk.bb , and bitbake is giving preference to the first one, requiring linux-yocto-rt as the PREFERRED_PROVIDER (the second one requires linux-intel-rt instead)

I also changed the priority of the meta-intel layer from 5 to 6, but to no effect.

Could somebody be so kind as to tell me what am I missing here?

Thank you in advance and best regards

Hi Daniele,
maybe you forgot to add your layer *meta-mytest* to *bblayers.conf* ?

Ciao

Thank you Marco,

it is there:

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
POKY_BBLAYERS_CONF_VERSION = "2"

BBPATH = "${TOPDIR}"
BBFILES ?= ""

BBLAYERS ?= " \
/home/vboxuser/yocto/poky/meta \
/home/vboxuser/yocto/poky/meta-poky \
/home/vboxuser/yocto/poky/meta-yocto-bsp \
/home/vboxuser/yocto/meta-openembedded/meta-oe \
/home/vboxuser/yocto/meta-intel \

"

Grazie, ciao

I'd say including recipes across layers is not a good idea to begin
with. Rather copy, rename and tweak it.

What happens if you change the recipe like this?

*mytest-image.bb* :

```
inherit core-image

DESCRIPTION = "Just a test"

IMAGE_INSTALL:append = " simple-local"
```

Thank you for your reply.

I replaced the content of mytest-image.bb with that of meta-intel/recipes-rt/images/core-image-rt-sdk.bb and added

IMAGE_INSTALL += "simple-local"

at the end. This way I get a bootable wic, but find / -name simple-local finds nothing.

Thank you Marco.

Adding inherit core-image as suggested, I still get

ERROR: Nothing PROVIDES 'mytest-image'
mytest-image was skipped: Set PREFERRED_PROVIDER_virtual/kernel to linux-yocto-rt to enable it

It could be that above IMAGE_INSTALL did not get effective. Check

bitbake-getvar -r mytest-image  IMAGE_INSTALL

IMAGE_INSTALL="packagegroup-core-boot  rt-tests hwlatdetect kernel-dev simple-local"

By the way, rt-tests are missing too.

Re: [yocto] Problem with overlayed recipes

[Alexander Kanavin]

You need to inspect ${T}/log.do_rootfs for your image to check what is
actually being installed.

Also check the packages for simple-local to verify that they contain
what you expect to see on the image.

Probably I booted from the wrong pen drive, I have a bunch of them on my
desk.

So, copying the image recipe from the meta-intel layer to meta-mytest and
modifying it  did work.
I still am curious why the brand new recipe didn't.

Thank you and best regards.
