When IMAGE_GEN_DEBUGFS is enabled, and IMAGE_FSTYPES_DEBUGFS is left at its default (as suggested by local.conf.sample.extended), recipe parsing fails: bitbake kern-tools-native # or anything else for that matter ERROR: <poky.git>/meta/recipes-core/images/build-appliance-image_15.0.0.bb: No IMAGE_CMD defined for IMAGE_FSTYPES entry 'debugfs_vmdk' - possibly invalid type name or missing support class ERROR: Failed to parse recipe: <poky.git>/meta/recipes-core/images/build-appliance-image_15.0.0.bb Summary: There was 1 WARNING message shown. Summary: There were 2 ERROR messages shown, returning a non-zero exit code. i.e. bitbake doesn't even finish parsing... Since IMAGE_FSTYPES_DEBUGFS is based on IMAGE_FSTYPES, and since the build-appliance-image is setting IMAGE_FSTYPES to vmdk, image.bbclass/image_types.bbclass will be trying to build a debugfs_vmdk, causing the error, as this is not implemented. One solution to solving this problem could be as simple as adding a line IMAGE_FSTYPES_DEBUGFS_remove = "vmdk" to the build-appliance-image recipe, but that is very specific to the error encountered and carries the risk of the error being reintroduced in another recipe. Another solution could be to add 'debugfs_vmdk' to IMAGE_TYPES_MASKED in image-vm.bbclass, but again, this approach doesn't seem generic enough. None of the live and vm type images have an implementation for building a debugfs version, it doesn't seem to make sense to build debugfs versions of any of them anyway, and given IMAGE_TYPES_MASKED appears to be intended for those image types exclusively, it seems the right approach is to unconditionally also mask all debugfs_ flavours from IMAGE_TYPES_MASKED to achieve a generic solution. Do that so.

Poky
Poky is an integration of various components to form a complete prepackaged build system and development environment. It features support for building customised embedded device style images. There are reference demo images featuring a X11/Matchbox/GTK themed UI called Sato. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at: http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions of OpenEmbedded. It is distro-less (can build a functional image with DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website: http://www.openembedded.org/
Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
Everything else should be sent to the OpenEmbedded Core mailing list. If in doubt, check the oe-core git repository for the content you intend to modify. Before sending, be sure the patches apply cleanly to the current oe-core git repository.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of oe-core and poky-specific files.
