Must have been WAY harder than he originally thought. I would have expected that the BeagleBoard has such wide application that RTAI would have wanted to make a port available for it. I have used the original BeagleBoard in one project, and it was really great. It is a signal multiplexer to go in an area that becomes inaccessible when equipment is running. It allows the operators to remotely check on equipment in that room. I created a TCP server, it is a single file of C code about two pages long, and is started as a service in the /etc/init.d files. The ease of setting up the TCP server was really mind-boggling. 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! Yes, he's still picking away, but I have no idea how much closer it might be. Jon -- Try before you buy = See our experts in action!

Has something happened recently concerning RTAI and the BeagleBoard/OMAP3? Also, since then the BeagleBone has come out, which has more GPIO pins. It has a TI AM3358 ARM Cortex-A8 CPU running at 700 Mhz. They claim over 1.5 billion Dhrystone operations per second and vector floating point arithmetic operations. http://beagleboard.org/bone -- Keep Your Developer Skills Current with LearnDevNow!

I know that completing a port like that was WAY out of my league. Jon 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. Regards, Kent -- Try before you buy = See our experts in action!
