[12:00:51] <anton_t> I'm a software developer who knows how to get c programs compiled with gcc and use make files, what's the OLinuXino board you would suggest I get if I want it to control a pursa 3d printer or 40w laser cutter?
[12:01:29] <leon> hi
[12:02:12] <braunr> anton_t: any really
[12:03:37] <braunr> although the best supported are the older 32-bit cortex-a based ones
[12:03:46] <braunr> imx233 is old and with a classic arm processor
[12:04:15] <braunr> the virtually-indexed virtually-tagged cache adds overhead to an already old and slow processor
[12:04:47] <braunr> the newer a64 is good though some devices are still not well supported, but it's being worked on
[12:04:54] <braunr> especially by some people from the buildroot project
[12:05:25] <braunr> i think the a20 is the best supported one
[12:06:20] <anton_t> ok I'll have a look at the a20's
[12:07:20] <braunr> i personally use buildroot on all my olinuxino boards
[12:07:44] <braunr> the device you want to control uses usb i assume
[12:08:54] <anton_t> I was hoping to put either real time linux on it and use it to directly control the motors
[12:09:02] <anton_t> after getting leds to blink :)
[12:09:30] <braunr> yeah you can do that
[12:09:37] <braunr> although i don't personally recommend the preempt-rt patch
[12:11:02] <braunr> it depends on your rt needs really
[12:12:14] <braunr> but again i would recommend using buildroot
[12:12:21] <anton_t> not really I'd just like to play around with it
[12:12:45] <braunr> this way you'll have cross-compilation, kernel patching, and ofc the rootfs, all integrated
