Other Parts Discussed in Thread: OMAP-L138

Using CCS, is it possible to run two projects simultaneously on the ARM and DSP cores?

Hello,

Would you mind going through the process on how that is done (or pointing me to a document that explains it)?

Thanks,

Justin

I am trying to do this for the OMAP-L138.

Anyway this is a question for the CCS forums. Not sure if any of the moderators will move it. I don't have that authority. You might want to start a new thread there.

Most of CCS functionality should be documented in online help or the processors wiki. Details would require that you specify what version of CCS you are using. And it is much easier to answer specific questions than describing a generic process...

Regards.

A good place to get started is with the below wiki topic:

http://processors.wiki.ti.com/index.php/Multi-Core_Debug_with_CCS

Not specific to L138 but the same concepts apply.

Thanks

Can I have two separate projects running at the same time?

Thanks,

Justin,

Yes you can, provided they are running one in each core.

Hello,

I've been working on the OMAP-L138. I have succeeded in loading a project onto the DSP and a project onto the ARM. However, I am running into problems in getting them both to run correctly at the same time. In particular, only one of them can output to the console at the same time - this may not be that only one can output at the same time, but only one is... Any ideas?

By the way, I've loaded them onto the OMAP-L138 by Selecting Launch Configuration, and manually turning on the individual cores. Then loading a program on to each one. Is this the correct way to do it?

Thanks,

Justin

Justin,

Check the post below that talks about the dual console output. Although there is a bug reported for CCSv5, the suggestion I give there is valid for CCSv4.

The way you loaded code is correct.

Cheers,

Rafael

Rafael,

The debug box shows both of my cores "Running", but one core will not output to the console (or do anything for that matter). I have confirmed this with the switching consoles, and the lack of one of the projects outputting to the UI board. I may be running the programs incorrectly. Enabling "Synchronous Mode" gives me the same problem. Is there a special way to run projects after they have been loaded onto the cores? Also, do I need to edit my projects to give them projects special settings to run at the same time?

Thanks,

Justin

Rafael,

Are you looking into this or do you consider this issue closed?

Thanks,
