Hi!
I have a number of products with am335x processors running at different
frequencies. In fact the processors are marked with different suffixes. For
example I have am3352bzczd30 (300MHz) and am3354bzcz100 (1000MHz). Of
course the linux kernel is the same for both products but the system does
Hello,
First off, a little about my BBB software version:

Linux beaglebone 3.8.13 #1 SMP Wed Sep 4 09:09:32 CEST 2013 armv7l GNU/Linux

Distributor ID: Angstrom

I am porting a piece of software to the BBB. To make my life easy, I would
like to know if there is some predefined compiler macros that would
identify the compilation platform which in this case is a Beaglebone Black.
I know that __arm__ is defined but that isn't good enough. I am porting

Like the DMA controller, the PRUSS operates as a bus controller and

How are you powering your BBB?
I've heard that if you power it via USB instead of the 5V DC connector,
that the CPU speed will be reduced due to the lower power.

We test the boards at the factory at 1GHz on USB and DC prior to shipping.
The issue there is if you have a SD card, then that can exceed the 500mA

I recently got my beaglebone black, and thought that it would be a great
