I started with Michaels's BBW work here: http://static.mah.priv.at/public/beaglebone/
The BBW 3.2 kernel won't work on the BBB, so I had to build a kernel. Here's a working 3.8.10 kernel for BBB: kernel-3.8.10-vanilla.tgz It's a vanilla kernel; there's no xenomai for 3.8 yet, so you're not going to get proper realtime yet. Procedure: download beaglebone_sd4GB.img from Michael's site above flash that image onto a 4G or bigger uSD card download kernel tarball above mount the root partition of the uSD card, untar kernel tarball into the root. It contains uImage, the dtb file, and all the kernel modules. unmount and boot on BBB. Now you have a running debian system. Michael's image comes with two different source trees of linuxcnc; I believe they're mainline and Charles's pru branch. If you want to try my gpio driver, you can switch to my branch and check it out: from within one of the linuxcnc source dirs: git pull git checkout -b bb-hal-gpio origin/bb-hal-gpio now you need to build linuxcnc without realtime threads (since we don't have an RT kernel yet), enabling hardware drivers and BB platform: ./configure --with-threads=posix --enable-drivers --with-platform=bb make sudo make setuid should do it. Note that it takes awhile to build on the BBB :) Hope this helps, shoot me an email if you have any further questions!
