Subject: pxassp dma pointer not moving
Date: Sun, 22 Feb 2009 22:47:21 +0100	[thread overview]
Message-ID: <20090222214721.GB5893@buzzloop.caiaq.de> (raw)

Hi,

I'm currently implementing support for a board based on a PXA300 with an
I2S codec (CS4270) next to it. Things do work in general, including the
setup of the SSP engine and clocks, and when using the OSS compat layer,
I can see data on the bus. With the native ALSA API, however, the DMA
pointer does not move forward but is stuck at position 8. ALSA's core
calls pxa2xx_pcm_pointer() a couple of times and eventually gives up on
it. Unfortunately, I don't have a Zylonite board for cross-check; could
anyone verify that things are not currently broken in a general way?

My code base is up-to-date to sound-2.6.git/for-2.6.30.

Thanks and best regards,
Daniel
