Yocto, OpenEmbedded, and TI layers
The Yocto, OpenEmbedded, and TI layers contain the key information on which the u-blox layers are created
upon. The u-blox layers require a specific revision of the layers and are managed by the setup script.
6.4
Working with the meta layers
Sometimes, it is necessary to modify or override the settings in a layer. The default way to modify the layers is by
creating an override layer with a high priority. Bitbake will parse all layers specified in the bblayers.conf and
resolve the dependencies and priorities.
6.4.1
Creating a new meta layer
Yocto provides a script that assists in creating new meta layers.
Goto the poky directory and source the ublox-init-build-env file and then start the Yocto layer setup script.
Choose default priority and create an example recipe named bar. Skip creating a bbappend file.
$ cd poky
$ source ublox-init-build-env
$ cd ..
$ yocto-layer create foobar
yocto-layer create foobar
Please enter the layer priority you'd like to use for the layer: [default: 6] 6
Would you like to have an example recipe created? (y/n) [default: n] y
Please enter the name you'd like to use for your example recipe: [default: example] bar
Would you like to have an example bbappend file created? (y/n) [default: n] n
New layer created in meta-foobar.
Don't forget to add it to your BBLAYERS (for details see meta-foobar\README).
