I am really admire the great job have been done by you guys.

I am just start working on using BBB but limited to normal usage only. Now, I have decided to move on to do real-time task and I found your link and tutorial, I am happy to see that! But I have a question regarding to the image of the chosen OS(debian) by you guys to demonstrate the usage of PRU, does it bound to that particular OS only? I am having Arch linux Arm version on my BBB, I hope I can utilize it on the SPI communication, just not sure is it compatible or not. I wish I can learn as much as I can from you guys.
