BCLK & LRCLK ( WM8962) SABRESD IMX6 board

Question asked by Raghunandan D K on Mar 18, 2015

Greetings !

 

I am referring the document IMX6QLXRM Rev L3.0.35_4.1.0, 09/2013.

Section: 23.4.1 ASoC Driver Source Architecture

Table: 23-1 Stereo Codec SoC Driver Files (WM8962.c)

Freescale Kernel source code:  http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git

Branch: remotes/origin/imx_3.0.35_4.1.0

 

We have a requirement to try out the linux-3.4 kernel on the sabresd board, we have moved over the files listed in this section to the 3.4 kernel.

However even thought  the wm8962 driver gets registered and is shown ( $ aplay -l ) when we play an audio sample we observed that the

BCLK and LRCLK is not getting clocked and so also the MCLK/XTI.

Any clues please ?

 

Warm Regards,
Raghu
