As such, they start with a whole bunch of different layers, most of which are BSP layers, and then simply do: $ MACHINE= bitbake e.g. $ MACHINE=raspberrypi2 bitbake angstrom-image $ MACHINE=beaglebone bitbake angstrom-image ... and build the exact same image for a bunch of different boards/machines. They've recently switched to using a repo manifest (which I think is a great idea): https://github.com/Angstrom-distribution/angstrom-manifest I've been playing around with doing essentially the same thing for a "poky" distribution here (but it's still a work-in-progress and not really ready for prime time yet): https://github.com/twoerner/layer-repos > Seems > to me that is the ideal goal of Yocto, but I don't see many BSPs > listed under the project > downloads page. Take a look here: http://layers.openembedded.org/layerindex/branch/master/layers this is the "master" list of all the "known" layers, recipes, etc. As you can see, there are quite a few BSP layers.
