Note that you can easily cross-compile kernels...building Linux natively on these ARM boards is painful, and on many systems capable of running Linux it's just plain impossible (at least without massive upgrades to available memory/disk). I haven't experimented with cross-compiling LinuxCNC. That's more mountain than I want to climb right now. :) <snip> > As for the Raspberry: that has very limited potential - the > platform is about half as fast as the Beaglebone, has fairly > minimal GPIO, and it is wed to the Broadcom chipset, which I would > rate as a company which still doesnt get it.

Even worse, the Pi isn't an ARM chip with a bunch of stuff attached, it's a black-box video decoder/GPU that happens to have an ARM as a co-processor. The GPU is in total control of the system (including booting from flash), everything about the GPU is undocumented, and the GPU can eat up as much bus/memory/system as it wants, holding off even a real-time Linux kernel for unknowable amounts of time. I agree with you that Broadcom doesn't get it, and TI does. - -- Charles Steinkuehler [email protected] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAlC8kKwACgkQLywbqEHdNFy6twCcDpJHxKPLeZvdh0qkkfhW0rOq WN8AoIMd94vUzsaQlz9s/qRzt1lLsNoR =QJ7F -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Keep yourself connected to Go Parallel: BUILD Helping you discover the best ways to construct your parallel projects. http://goparallel.sourceforge.net _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
