i want to build a bootable system for a BBB, and i can see at least
three possibilities:
1) the meta-yocto-bsp layer defines the beaglebone as one of its

3) there is a "meta-beagleboard" layer, but that one looks a bit
stagnant
any preferences out there for people working with the BBB?
The generic "it depends" answer applies here.
Due to the efforts of TI,the core BBB support made it into the
mainline kernel for 3.14, so that forms a common baseline of feature
support.
Outside of that, it depends on the functionality you need in the
image and your familiarity with integration of multiple layers and
features.
meta-ti gets you the latest and greatest features and support, while
the reference BSP was also done by TI to provide a good baseline
level of support (graphics, usb, ethernet, etc) and is supported via
Wind River in the linux-yocto repository.
excellent. since i want to configure and build for a classroom
environment and probably don't need bleeding edge, i'll stick with the
yocto-bsp stuff, which has served me well thus far.
The big thing missing from this version(*) is no cape support,
so if you need an LCD display or CAN driver or ..., you're not
going to find it. The meta-ti version does support those AFAIK
(*) unless this changed in the last three weeks while I was on holiday :-)
