[alsa-devel] Arecord issue

    I am working on a 2.6.37 kernel and on a DM365 davinci board with a
tlv320aic3254 audio codec (i2c control lines, i2s data transfer)
I wanted to get the audio up on my board so got the alsa-lib and alsa-utils
1.0.25 compiled them and got the aplay to work fine.
When I got to working on the arecord things haven't worked fine. I have
traced all the calls and have reached so far;
codec gets set properly
davinci_pcm_trigger executes with success
snd_pcm_sw_params() executes successfully.
aplay calls begin_wave()
aplay calls pcm_read() that invokes  snd_pcm_readi()
Finally my app seems to not go beyond the snd_pcm_start()

Any assistance shall be highly appreciated!

Thanks in advance,
