Well after considerable delay, I now have two working A13-Olinuxino-wifi
boards. I was sent two replacement boards direct from Bulgaria confirming
that there was something wrong with the SD ports on the two I received from
a local supplier.

I have now managed to successfully compile a very slightly customized kernel
(only enables the GPIO on the Olinuxino), install on an SD with a Debian
Wheezy image, and boot from the SD.

I am now looking to patch the kernel for Xenomai. I have the
arm-linux-gnueabi cross compile tool chain installed on an X86 ubuntu 12.04
machine, although I expect the Olinuxino has sufficient horse power to
compile in situ as well. I see some basic instructions on doing this with
Michael's prebuilt kernel  for the Beaglebone here:

xCNC

In searching around I found some generic notes which I think I can work with
here:
http://wiki.micromint.com/index.php/Electrum_Xenomai_Notes

I know Michael previously mentioned something about needing a high res
timer.

At any rate, I seem to be at the point in the road where it would be
beneficial to choose my rut wisely. Any pointers or other references for
getting started would be appreciated.

Thanks,
Eric
