Getting Code Composer into BB-xm for testing.

Right now I need to write a simple "blink the LED" app for BB-xm.
However, I can't figure out how to get it into BB-xm to test it, and
how to access the low level stuff like that. Ultimately, I need to be
able to access the hardware itself and skip the OS..so below the OS.
Any help?

You are in luck. You landed the FAQ answer of the week...

Compiling anything to blink an LED is overkill. The quick answer is
just use the kernel: http://www.kernel.org/doc/Documentation/gpio.txt

If you are stuck on using CCS, that is available for download, so:
http://processors.wiki.ti.com/index.php/Category:Code_Composer_Studio_v5

There is an SDK that might help you get started with step-by-step
instructions, so: http://processors.wiki.ti.com/index.php/Sitara_SDK_5.03.02_Release_Notes

CCS is Eclipse, so this might help a bit in thinking about it a bit
broader: http://www.lvr.com/eclipse1.htm

The hardware is abstracted, so just use the abstractions:

If you are hung-up on accessing the registers directly, google the
application 'devmem2' and see how to map registers from userspace.

Oh, and if you really want to skip the OS, I suggest you look at the u-
boot SPL code and create your own MLO: http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=summary

I am indebted to you! Thank you much for your assistance and research.
Actually, I don't need to do that project specifically [LEDs], I just
needed a project to test code at that level, and that allowed an
outcome I could see. Any further suggestions? And again your help is
very much appreciated!

What *is* Puppybits??? There's no there there.

A handful of source files, no documentation... no
activity since April 2010.
