change the codec.....

sunny sour

HI, I am working on pandaboard(omap4460) and I want to change the codec..... I want the signal out from the mcbsp2 instead of mcpdm....

I modify the sdp4430.c

{
  .name = "wm8978-lp",
  .stream_name = "Multimedia",
  /* ABE components - MM-DL (mmap) */
  .cpu_dai_name = "MultiMedia1 LP",
  .platform_name = "aess",
  .dynamic = 1, /* BE is dynamic */
  .dsp_link = &fe_lp_media,
},

/*
* Backend DAIs - i.e. dynamically matched interfaces, invisible to userspace.
* Matched to above interfaces at runtime, based upon use case.
*/

{
  .name = OMAP_ABE_BE_MM_EXT0_DL,
  .stream_name = "PCM Playback",
  /* ABE components - MCBSP2 - MM-EXT */
  .cpu_dai_name = "omap-mcbsp-dai.1",
  .platform_name = "aess",
  /* FM */
  .codec_dai_name = "wm8978-hifi",
  .codec_name = "wm8978.1-001a",
  .no_pcm = 1, /* don't create ALSA pcm for this */
  .be_hw_params_fixup = mcbsp_be_hw_params_fixup,
  .ops = &carsmart_abe_ops,
  .be_id = OMAP_ABE_DAI_MM_FM,
},

and I make it out to the MM_EXT_DL...... but howerver there is no signal out from the mcbsp2 ...

here is the log

here is the log:

Hi Sunny,

Can you tell me what release are you using to verify the changes you are doing are correct?. Thank you

Thank you.....

I just changed the abe..... and the codecs will be later...

the route of the abe i want to get is that:

MultiMedia1 LP Playback -> MM_DL_LP -> MM_DL VMixer -> DL1 Mixer Multimedia -> Sidetone Mixer Playback -> DL1 MM_EXT Switch -> MM_EXT_DL

--------------------------------------------------------------------

SND_SOC_DAPM_AIF_OUT("MM_EXT_DL", "PCM Playback", 0,
W_AIF_MM_EXT_DL, ABE_OPP_25, 0),

-------------------------------------------------------------------

MM_EXT_DL will be out to PCM Playback right?

--------------------------------------------------------------------

  .name = OMAP_ABE_BE_MM_EXT0_DL,
  .stream_name = "PCM Playback",
  /* ABE components - MCBSP2 - MM-EXT */
  .cpu_dai_name = "omap-mcbsp-dai.1",
  .platform_name = "aess",
  /* FM */
  .codec_dai_name = "wm8978-hifi",
  .codec_name = "wm8978.1-001a",
  .no_pcm = 1, /* don't create ALSA pcm for this */
  .be_hw_params_fixup = mcbsp_be_hw_params_fixup,
  .ops = &carsmart_abe_ops,
  .be_id = OMAP_ABE_DAI_MM_FM,

case OMAP_ABE_DAI_MM_FM:
if (stream == SNDRV_PCM_STREAM_PLAYBACK) {

   /* port can only be configured if it's not running */
   if (omap_abe_port_is_enabled(abe_priv->abe,
     abe_priv->port[OMAP_ABE_BE_PORT_MM_EXT_DL]))
    return;

   printk("%s MM_EXT connection to McBSP 2 ports \n",__FUNCTION__);

   /* MM_EXT connection to McBSP 2 ports */
   format.f = 48000;
   format.samp_format = STEREO_RSHIFTED_16;
   abe_connect_serial_port(MM_EXT_OUT_PORT, &format, MCBSP2_TX);
   omap_abe_port_enable(abe_priv->abe,
    abe_priv->port[OMAP_ABE_BE_PORT_MM_EXT_DL]);

_______________________________________________________

and then it wil be out to mcbsp2(48k or 44.1k) right?

and the log show that

is that right?

Hi Sunny,

I thunk I understand what you are trying to do, but I think it is not necessary to add too many changes since there is a Back end configuration named "FM" ready to use McBSP2. All you would need to do is to change the codec for yours and change the McBSP configuration in case you want another. Have you try to do that?

change the codec.....
