[meta-xilinx] Newbie woes

Hi Rich,

Addressing your original post, it always helps if you can include the bitbake
summary at the start of the build, then we can see what layers (and their
commit IDs) are being used by your build.
Failing that though, I noticed that one of your warnings "WARNING: No recipes
available for:"
was for linux-xlnx_3.14.bbappend.
This is on the master branch of meta-xilinx so I think you have a mismatch
with poky-dora-10.0.1.
In any yocto/open embedded development you need to maintain consistency with
layer branches or you will get these recipe warnings due to "layers"
having different versions of recipes.
You will need to check out the dora branch of meta-xilinx (and any other
layers you are using): "git checkout dora" in your meta-xilinx directory.

Regarding the dtb files, (this is relevant on master branch, they had
different naming on dora branch).
meta-xilinx master (daisy branch to be) has
linux-yocto kernel "targets": built against
git.yoctoproject.org/linux-yocto_?.??.git with a few patches as necessary.
linux-xlnx kernel "targets": built againts github.com/Xilinx/linux-xlnx.git
The kernels differ in their dts requirement, so two dts/dtb files are necessary.
Pick the one you are building the kernel for (by default linux-xlnx).
But as I mentioned when you use the dora branch of meta-xilinx the naming
convention is different and the same dtb files exist. If you are interested,
search through the meta-xilinx mailing list and you will find posts about
this shift in linux-yocto targets between dora and now master branch.

I'm hoping that if you use dora of meta-xilinx you will start to get a
working build and booting image. Give it a try and see if the recipe
warnings go away. Given you are not using a supported distribution you may
find some host related issues, but fingers crossed.
Regards
Sipke
