CSL_I2S_AudioCodecDMA example with TMS320C5515 eZdsp

Hi,

I'm new to C5515 and CCS

I'm using TMS320C5515 eZdsp board and CCS 6. I'm trying to run demo CSL_I2S_AudioCodecDMA from c55_csl_3.0.6 library, but without success.

The code is running, but I don't hear any sound routed from my PC to Stereo Out. 

Is there any thing i can do? In Readme.txt i found only indications about C5515 evm...

Thanks In Advance

Paolo

    Paolo,

    Please ensure that you have the correct platform specified in csl_general.h for C5515.

    Also note that there is a new version of the C55x CSL v3.07 from http://software-dl.ti.com/dsps/dsps_public_sw/dsps_swops_houston/C55X/latest/index_FDS.html

    Yes, in cal_general.h i have commented the line:
    //#define CHIP_C5517
    but nothing happens...
    here is the code of csl_general.h:

    ...

    Paolo,

    Your csl_general.h seems correct.
    Are you able to run the board demo from here support.spectrumdigital.com/.../ ?
    There is an I2S demo that also plays a 1khz sound.

    Yes, but only in CCS v4.

    Thanks,
    Paolo
