>From my perspective, the fancy BeagleBone specific kernel bits that Bas is wanting are not particularly necessary for LinuxCNC. Running under Xenomai, we can't call into the Linux kernel to update anything without a severe latency hit, so we'll have to talk to the raw hardware anyway. It's easy enough to talk to the PRU directly since it's unused by Linux, but some of the other hardware (like the ADC and PWM) is a bit trickier. I'm actually hoping I don't have to *disable* the Linux drivers for the AM335x hardware to keep the kernel from stepping on registers while we're talking directly to the hardware via Xenomai/userspace. -- Charles Steinkuehler char...@steinkuehler.net ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
