check http://osadl.org .. if you can find some system resembling the beagle board in the test rack, they have a number of ARM versions. If not ... send a beagleboard :-D ......
Anyhow, latency will not be better than what osadl are getting, sometimes a system gets worse latency from a driver, once found you can always fix the driver. EMC on the beagle board would be 'super nice' ... but I don't think the latency from RT-Preempt on ARM will be good enough for servo loops, it might be good enough for 'rep-rap' and similar ... ie. steppers ... / regards, Lars Segerlund 2011/6/17 Jon Elson <el...@pico-systems.com>: > EBo wrote: >> Agreed.
