Problem with third sgtl5000 codec

[caiopereira]

I'm using IMX6Solo with 3 codecs (SGTL5000).

First Codec is in the SOM (Toradex Colibri IMX6Solo 256MB)  is connected to the i2c-2 and ssi1 - Working Ok

Second Codec is in the base board is connected to the i2c-4 and ssi2 - Working Ok

Third Codec is in the base board is connected to the i2c-1 and ssi3 - Not Working 

To test the codecs I'm using the aplay.

 aplay /usr/share/sounds/mysound/ringtone1.wav -V mono -Dhw:0,0 -v              ( Ok )

 aplay /usr/share/sounds/mysound/ringtone1.wav -V mono -Dhw:1,0 -v              ( Ok )

 aplay /usr/share/sounds/mysound/ringtone1.wav -V mono -Dhw:2,0 -v             ( Ok )

When I test with -Dhw:2,0 the aplay freeze and crash.

I'm trying to find the problem in my devicetree, maybe could be a problem with SSI3 Pinout Routing.

Hi,

We have setup Yocto project 4.9.11_1.0.0 on a imx6qpsabresd based custom board which has two of wm8962 audio codecs.

We have customized device tree file imx6qdl-sabresd.dtsi for dual audio codec configuration.(same as how it is done for sgtl500 above). But we are getting kernel panic and it is not detecting two sound cards.

Do we need to modify board files and driver files (imx-wm8962.c and wm8962.c).

Please let us know how we have to take care of dts and driver files for dual audio codec configuaration.

Thanks,

Devika

Hi Caio

seems for ssi3 "int-port" should be 7, not 3 as described in

Table 80. AUDMUX Port Allocation i.MX6SDL Datasheet

http://cache.freescale.com/files/32bit/doc/data_sheet/IMX6SDLCEC.pdf

Best regards
