Just wanted to know if anyone has tried.

Has anybody tried running EMC on an ARM based system? I have seen several dev kits at 800MHz, 256MB RAM, 128MB ROM, sd, usb, and large touch screens. I thought it would be a perfect fit for a machine..
I see that RTAI runs on ARM, so it should be possible to make it work, but it sounds like an awful lot of work.
The Atom330 micro-ITX boards are a much more straightforward proposition (lots of people have already used them, and the latency is very good)

I can get these boards: ARM Cortex-A8 units for quite cheap and they have 3D openGL GPU's, DSP for video, 256MB RAM, and 256MB ROM. They can run at a max of 720MHz at ~1440mips
I see RTAI supports ARM7 (v4T) and StrongARM so it shouldn't be to much hassle to port to an ARM Cortex (v7T) For processor info goto Wiki and under OMAP3 see OMAP3530.
How portable is EMC? I have not even looked at the source yet...

You would probably have to write your own driver to get EMC2 to drive that IO.My design goal is a completely self contained controller and I would like to run my I/O directly off the chip to remove all possible lag.
I don't think EMC supports any USB devices for motion control.(USB is inherently non-realtime).I could use a micro-atx atom motherboard and a usb breakout for my I/O
For other alternatives look at:
wiki.linuxcnc.org/emcinfo.pl?EMC2_Supported_Hardware
I am happy with the Mesa 7i43, but your requirements might be different,
It's open source, so inherently portable. How much work do you want to make for yourself though?How portable is EMC? I have not even looked at the source yet...

Considering you can get a dual core Atom + motherboard for less than half that price, it seems like a pretty high price for what you get.MicroMinded wrote:I can get these boards: ARM Cortex-A8 units for quite cheap and they have 3D openGL GPU's, DSP for video, 256MB RAM, and 256MB ROM.

I would like to help with this.
I also started with embedded arm in the mini2440 arm board.
im a litle newbie, so i had much difficulties, starting with porting linux to arm.
i had compiled the 2.6.32 kernel with rtai, but it didnt worked, something was wrong.
so, if you decide to continue with this im with us.

It seems someone already implements a similar project
You can tell me, this:
Kernel version?
linux distribution?
RTAI version?
EMC2 version?
whit you make this job?.
thanks.
