This one is known, we are balancing the fact that the beagle board exists in multiple kernel versions and 2.6.37 is a transition point for the serial .. so the docs haven't been update with that change yet. > * There is no video? /dev/fb0 is not being created. > > I know that the previous (Angstrom based) 2.6.32 kernel had > lots of additions which support video (DSS subsystem) and > also camera (ISP).

We are moving onto some other beagleboard variants, so left the forward port of the beagleboard at mainline status (which is enough to meet the existing demo requirements). So whatever has made it to the mainline 2.6.37 kernel works, which is largely what you are seeing. What we are building up for the supported boards is a common set of features (tracing, boot media, filesystems, configuration, etc) that are uniform across architectures and boards. That in turn extends our ability to build, validate and maintain many more boards that would otherwise be possible. On top of the common feature set, comes the board specific functionality. That functionality is selected / ported from the best sources (and is hopefully something on its way to mainline). That porting effort typically comes after we have the base solidified and a board is of suitable interest to have this deeper support (or if patches are contributed). Anyway, that doesn't answer your question, but explains what/why things may appear to be in an early phase of support. Cheers, Bruce > > Thanks >
