The BeagleBoard-xM is a nice unit, but you're facing several hurdles in using it with LinuxCNC: * It uses a different CPU than the 'Bone, so it will be difficult to leverage the work happening with LinuxCNC on the BeableBone. * It has less available expansion I/O, and the extra built-in I/O isn't particularly applicable to machine control (ie: DVI, S-Video, audio in/out). * There is no PRU available for direct real-time control of I/O. There is a DSP available, but you (or someone) would have to write code to make it useful. I have not reviewed the data sheets to see how suitable the DSP is for real-time I/O control, but it's intended purpose is for audio and video decoding, not real-time I/O processing. While the BeagleBoard-xM could possibly make a good platform for LinuxCNC (especially with a small FPGA based expansion I/O board), you'll probably face a lot less work using the 'Bone for LinuxCNC (unless there's someone working on supporting the xM who hasn't been posting here). - -- Charles Steinkuehler char...@steinkuehler.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlD5o/gACgkQLywbqEHdNFz2fQCeIcn+PF8425X7FWw7eLB/TVIm +NIAoJuSw6Cnton8QUkK21SFxt8j+Ebv =eYQ1 -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.
