TM320C6424 Evaluation Module and codec G711

Hi

I've a board TM320C6424 Evaluation Module and I need to know how to  use the  current codec  G711  provided  on Cd board and properly   how  to modify the linker 

I would be  thankful for any help.

Thanks a lots in advance.

  • There should be some example code in the software install to exercise the G711 codec, have you taken a look at the example? As to modifying the linker, I am curious what you mean, how do you need to modify it?

  • Hi!

    Thanks a lot for your quick reply... When I wrote "modify the linker" I mean how can I modify or generate the linker command file? I'm in trouble because I can't understand the mechanism of the linker command file and I need some indications to proceed.

    About the G711 codec, there isn't the exercise you indicate: how can I get the example?

    Best regards

    With most projects these days the linker command file ends up being generated by DSP/BIOS, so you would configure your memory map in the DSP/BIOS GUI configuration tool and than when you build your project the BIOS configuration will generate a linker command file for you (typically <nameofproject>cfg.cmd). If you wanted to do this by hand, such as if you wanted a custom linker command file, the documentation on the format is given in section 7.5 of SPRU186.

    If there was a codec included there should be an example with it, I am curious where you got the codec from? I took a look at the EVM software package posted here, but I do not see the codec in that install and thus no example. If I can find the codec you are referring to, I can probably find an example too.

  • I got the codec from Spectrum Digital Incorporated, with an evaluation module (TMS320C6426 - TMDSEVM6426 multirelease). I got the evm software package version evm6424_1_01_00_07.

  • It appears you are correct, for some reason the CD installer comes with a codecs folder, but the newer downloadable software package does not, and neither come with an example to build or exercise the codec. I think the best bet here may be to utilize an example from another similar platform, probably DM6437, I will have to see what I can dig up.

  • To follow up on this a bit, the best suggestion I have come across so far has still only been to use another software platform for a similar processor that does have the codec with examples, in particular DM6437. Of course the DM6437 has video ports and such that are not on the C6424 but from an audio perspective they are about the same, so you should be able to use the audio specific examples from DM6437 on a C6424, this being said you can download the DM6437 DVSDK from here.
