Mic [Uplink] Not Working using Omap-LInux 3.4 Kernel

Other Parts Discussed in Thread: TWL6040

Hi I took linux 3.4 Kernel from below git and modifications to make it work on my Omap4460 board

git://dev.omapzoom.org/pub/scm/integration/kernel-ubuntu.git

Only playout is working but capture is not

In this release is the Mic Tested for Blaze /Panda?

How can I debug this Issue?

static struct omap_abe_twl6040_data sdp4430_abe_audio_data = {
.card_name = "SDP4430",
.has_hs = ABE_TWL6040_LEFT | ABE_TWL6040_RIGHT,
.has_hf = ABE_TWL6040_LEFT | ABE_TWL6040_RIGHT,

.has_aux = ABE_TWL6040_LEFT | ABE_TWL6040_RIGHT,

.has_abe = 1,
.has_mainmic = 1,
.has_submic = 1,
.has_afm = ABE_TWL6040_LEFT | ABE_TWL6040_RIGHT,

.jack_detection = 0,
/* MCLK input is 38.4MHz */
.mclk_freq = 38400000,
};

I used above data in board File. Is there a way to check mcpdm is recieving Uplink/Capture Mic Data

Thanks

Hi Kavitha,

As per my understanding, the generic linux releases for OMAP4 namely GLP 1.6.6 which is the latest does not support Audio record as per the Release notes for GLP 1.6.6 release. That is, it has not been tested for Audio Record yet as this feature is yet to be supported.

Thanks & Best Regards,

Venkat

Hi Kavitha,

The releases are only tested on Blaze and Blaze Tablet, Panda is supported by the community. Did you try recording using Blaze?

Can you try running tinymix and omapconf to dump twl6040 registers?
