Hello,

I am using Debian image on my BBB, and want to learn how to program PRU as 
quickly as possible. (Deadline is pretty much close, 1.5 days left :) )

What I need to do is: 

* First I should be able to toggle GPIO pins on and off by using PRU
* Then I need to establish communication between Cortex A8 and PRU such 
that, according to what A8 says, PRU will toggle that pin.

I am pretty new to these stuff, so do not have much idea about how to do it.

My first question is, do I need to buy something (debugger etc.) to be able 
to program the PRU?
Second question is more general: where should I start to accomplish what I 
just mentioned about. Could you please provide me some informative links? I 
guess there must be lots of people who have done what I want to do however 
couldn't find good sites.

Thank you all for your help!
