DSPLINK with omap-l138 and ccs4

Other Parts Discussed in Thread: OMAPL138

I'm having a rather difficult time setting this up, all we want to do is use the DSP for math functions called by the arm from wince, so lets just say there is no linux involved.  I can't seem to get the message example to build, I got to a linking error but kind of gave up for now. If any one can really provide step by step detailed instructions Its my first time tackling eclipse/ccs4 and developing on the DSP. Aslo if i were to edit an example to do this which one would best fit what I'm trying to do.

 

Thank You, any help is appreciated.

    Kevin,

    Your question is a little vague, but I guess what you're asking is how to get started with Link.

    There are a number of Wiki articles about Link, so if you haven't done so already, please check these out at http://processors.wiki.ti.com/index.php/Category:BIOSLink

    DSPLink package ships with sample applications. These sample applications are present at $DSPLink/gpp/src/samples (the hlos code) and $DSPLink/dsp/src/samples (the rtos code). The name of the sample application is indicative of the IPC that it is demonstrating.

    DSPLink also ships with a Users Guide and a Programmer's Guide in $DSPLink/doc. It would be a good idea to go through the documentation as well.  The User Guide will guide you through configuring, building and running the samples. The Programmer's Guide will guide you through an application writer perspective on DSPLink usage.

    You can also see if below example helps:

    I actually can build everything fine the problem I was having is creating a project in CCS4 that actually used the libraries that gets exported, none of the ways that were posted actually worked for me. Although I have gotten a project from the message sample working. I figured it  wouldn't hurt to ask the best way about doing what i need to do, I've already started reading the documentation, but since all i need to do is make 2 functions, one that will add two numbers, another that will subract  two numbers for now as an example for the person that will be porting over the math algorithms, I figured it wouldn't hurt to ask to narrow down the best solution for what I'm looking for.

    Are you looking for steps to integrate and build DSPLink examples in CCS v4? Please look here for details http://e2e.ti.com/support/embedded/f/354/p/72006/263967.aspx

    yes i saw those, for some reason none of them would work for me,

     

    i ended up making a hello world omapl138 project, copying the sample source and exports folders into the project, and copied the extra headers it was looking for, platform.h and c64xxdefs.h to get it to build.

     

    the only other thing i needed was in the export folders, i took the predefines from teh message text and that was pretty much it, the defines out of  CURRENTCFG.mk didn't work since it was missing a TASK_MSG and a few others.
