Trying to test the codecs on the DM816x dev kit

Simon Brown

Hi,

I'm a newbie to the TI processors/DSP and am really struggling. I have got my Virtual Ubuntu up and running, with serial port and NFS and can run the helloworld app!

Now I'm branching out a bit, and want to feed some data to a codec and see what it produces and am struggling to find anywhere to start. Within my helloworld.c file I now have CERuntime_Init() and CERuntime_Exit(). It took a while to set up the include paths to get these right, and then the xdc_target_types__ #define as well. But it now compiles, only to fail at the link stage because it can't find CERuntime_Init/Exit in the library.

Which library to I need to include? I'm currently just compiling it with the arm-none-linux-gnueabi-gcc tool - is this correct?

It has taken me too long to get here - any chance someone can send me in the right direction?

Cheers,

Simon

Simon,

You might want to start with one of the Codec Engine example programs. There is a file called build_instructions.html in <Codec Engine Install Dir>/examples, which describes how to set up your xdcpaths.mak file with locations to your tools and other products needed by Codec Engine, and how to build the examples.

Regards,

Janet

Hi Janet and Marcus,

Thanks for your replies - I'll try them out when I next get a chance, but it certainly sounds promising. I'll mark this as verified (if I can work out how), and if I get stuck again I can always unmark it or start another thread.

Cheers,

Simon
