Indeed. I've only just started playing with the RPi3 and have already hit some issues. I was hoping the GPU would be usable, but it looks like there are still problems. I think the BBB (or an SoC+FPGA) is probably a better choice if you don't need a native GUI, and if you _do_ want a GUI a low-end x86 box is likely a much better choice. I've ordered one of these x86 SBCs to play with and see if I can get it talking to Mesa hardware via SPI: http://up-shop.org/up-boards/2-up-board-2gb-16-gb-emmc-memory.html ...if it works out, it may be a good midway point between the ARM based SBCs and a full x86 machine. > https://wiki.debian.org/RaspberryPi > > Seems to suggest that armhf works on Pi >= 2.0 > > buildbot "sim" builds run with realtime on preempt-rt kernels. Yeah, I should be able to use the armhf builds if I'm running stock Debian (which works on the RPi 2 & 3). I started with Raspbian to see what the "out-of-the-box" experience is like, and figure it's unlikely I can tweak Debian to work better than Raspbian. I'm unclear what Gene's running, but I'm guessing it's Debian armhf rather than Raspbian. -- Charles Steinkuehler char...@steinkuehler.net ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
