Question about using ARM in OMAP

Pawel Pyszko

Hello. I'm trying to start ARM on OMAP. I just for starter want to start program which do nothing ( or even better: wake DSP ) I do not want to install Linux kernel. . I want my eXperimenter Kit from LogicPD to run autonomously without connection to CCS 4. Where shoud I start?

From what I've read I guess I shoud use sam AISgen tool and maybe same flash utility to write AIS to some memory ( don't know which ). Am I right? Can you help me with this task? I can't find suitable guide.

I read about programming ARM using CodeSourcery - shoud I start reading about this?

This guide should help you:

http://processors.wiki.ti.com/index.php/Boot_Images_for_OMAP-L138

The second example shows how to run DSP code as well.

Ok, I did run this 2 examples: one for ARM and one for DSP + ARM. Can you help me sum up?

To use both cores ( ARM and DSP) I have to write 2 separate programs in C++ and then compile it in CCS ( I used v3.3). So CCS can make .out files for both kinds of processors?

Than I used a AISgen tool to make AISimage. I manage to run programs only in UART2 mode from host drive by RS232. I couldn't write this image to non-volatile memory. In guide you recommended me is hint about C6000 Code Generation Tools. What for is this software? Is it something like CCS only without emulation mode?

Can you explain what you mean when you say "couldn't write this image to non-volatile memory"? You can use the software here to do that.

The C6000 Code Generation Tools contain the compiler and linker to create the .out file from your source code.

I just could not handle Code Generation Tools software like it was described in guide. It turned out it is not necessary.

About this examples - ARM example is working just fine, but I have problems with running DSP+ARM example. Sometimes it's working and sometimes not. I don't know why.
