I am a bit confused about few things.
In firmware release 9, 9.1, and 11, when downloading from source.sierrawireless.com yocto was always built for an mdm9x28.
When using leaf, suddenly yocto is built for an mdm9x06.
Looking at the product technical specification for the WP77XX the core is a mdm9x06 core.
Would the linux source built for an mdm9x28 be incompatible with an mdm9x06?
This is only half the problem though, as when I try to build the linux source after downloading using leaf it is missing the meta-swi-mdm9x06 layer and the build fails.
