as usual I probably bite off more than I can chew with my ideas. anyone play with this beast of
embedded boards
?
Curiosity killed the cat with an 8 core ARM processor. I know the wiki only seams to cover the beagle bone and raspberri pi. The xenomai project only seems to make mention of the much older and no longer supported odroid-pc.
This board does have a 30pin expansion port that supports SPI, GPIO, UART, and ADC.
(benchmarks are only a fraction of the story obviously and yes I know this board costs 4 times as much as some of the atom boards + difficulty level. )
I haven't purchased it, yet. still designing my electronic package for my mill.
on a side note, I have been to the boards a number of times and ponder if making all ARM related threads into a child board would be appropriate at this point. I know the BB has its own board but the raspberri pi seems to be an outcast. others even more so.

The BB header is a bit of an iceberg.
There is a huge amount of work going on into it, but it is largely on the user lists.
I think it is anticipated that when the work comes to fruition ( it is not far off ) there will be a huge ramp of interest, because the primary direction for the BB board work is reprap, which is becoming increasingly popular.
If JT wants to create a seperate Category for ARM and move the Pi stuff across, that might be a good idea.
The thread is already full of stuff that does not really apply to the Pi but was inspired by it.

Which ones? It seems pretty snappy, about 30 mins to compile a kernel for itself.
I do like the addition of the sata port on it. curious what the benchmarks look like.

I suppose the more important one would be what the jitter benchmark is to see if it's worth my time. I don't mind tinkering but in the end I do want my machine to have some decent performance for possible production work.

I was thinking of offloading step / pwm to the (onboard) Arduino. Though that looks harder than it should be as 115200 serial is the only link.
I got jitter about 20k with Xenomai, but that was a kludged kernel, and I couldn't make various patches from Gilles compile.

They have the RT Kernel ODROID:
github.com/hardkernel/linux/tree/odroid-3.8.y-rt
I liked the idea of ODROID, it is less expensive and power-full.
ODROID-U3 do not have many GPIO / SPI, but, have I2C, however, it is possible make over USB SPI similary the Udoo (working over USB and Serial to the GPIO/SPI/I2C).
I do not like SPI over USB, but They have github.com/hardkernel/Odroid-USBIO
I would like to see a better performance to run linuxcnc in a compact and inexpensive solution, I think the initiative with Raspberry and BBBlack very good, and better ODROID yet.
