I know what you mean, Jon. At the time you began talking up the Beagle Board I had just wrestled with the ARM-based 8" Chumby (actually the BestBuy version called the Insignia 8" InfoCast that I got at a fire-sale price), built a working cross-compiling toolchain, ported some bits and pieces of software and got them to run on the installed Linux, and then built my own Linux. Cocky from that exercise, I looked up the available material on the BeagleBoard and the available info on porting RTAI and was quickly deflated. I'd have to raise my skills a whole 'nother level or two or three .... I was just hopeful because of your last line "No RTAI so far, but that might come soon." I found another hopeful sign just this morning. At http://sourceforge.net/project/rtai-cortex/files/ there is a new file linux-2.6.20.13-5b27ed7.patch.bz2 (667.9kB) dated 2012-01-13. That's less than two weeks ago! I'm in no position to assess the progress being made by asprakash (tko79) and others, perhaps you are, but at least there is recent activity. Like you, I think the BeagleBoard is a potent contender. I bought an xM version to play with for possible mobile robotics applications with my grandkids but with my wife's health issues taking center stage I have only confirmed that it boots. The recently announced headless BeagleBone that Ron mentioned looks even better for my intended use, given its price and I/O.
