Two Audio Codecs SGTL5000 IMX6 Solo

caiopereira · ‎10-15-2015

Hi,

We're developing a board with two audio codecs SGTL5000 using a IMX6 Solo System On Module (Toradex Colibri IMX6). (Kernel 3.10.17)

The SOM has one sgtl5000 integrated connected at the ssi in the slave mode, We add a new sgtl5000 on the base board connected at the ssi master mode.

I modified all my device tree to adapt to I2S Master mode.

When I remove the sgtl5000 from the SoM manually (de-soldering) the kernel could attach my second sgtl5000 (base board).

When I use a SoM with sgtl5000 + a base board with sgtl5000 , the kernel could attach just one sgtl5000.

Using 2 sgtl5000 (SoM + Base Board)

Someone could help to fix this problem?

Thank you very much!

caiopereira · ‎11-10-2015

Thank you Jimmy,

We already decide to use the I2S Slave mode.

josbijma · ‎11-27-2015

Hi Caio,

I'm facing the same problem, we are using also an Colibri iMX6 and would like to use a second SGTL5000.

When configuring both SGTL5000 in the device tree the Codecs are not working even I2S is in slave mode.

Configuring only of the codecs in the device tree there is no problem registering the codec.

Did you solve the problem and could you share your solution with me?

caiopereira · ‎12-07-2015

Hi josbijma,

Sorry for the delay.

I asked to Toradex support and we wrote a little hack to support 2 devices (It's a ugly hack, sorry for this).

I don't know how to attach a file here , so I will paste the patch.

We're using the 3.10.17 kernel based on Yocto Dizzy , the Codec is working with external Crystal in I2S_SLAVE mode.

Hi Caio Pereira,

Thanks for your answer!

I tried the patch and it is working!

I'm not totally sure what the fix does. It seems that LDO initialization data is duplicated, is this needed because otherwise the previous data is overwritten/corrupted?

Do you know if a final solution/patch will be provided by Freescale or somebody else?

Again thanks a lot!

caiopereira · ‎12-09-2015

josbijma,

Nice!! We loose sometime to fix the software and hardware.

Yes, it's a problem with LDO initialization, I was thinking that the second sgtl5000 could be a new instance of the driver, so I didn't handle all the LDOs and instane in only one driver. This means I need to study more about device drivers.

I tested with kernel 3.14 and they didn't fix.

Best Regards,

caiopereira · ‎12-16-2015

josbijma

Are you using a 24Mhz Crystal for the second sgtl5000?

Best Regards,

Caio Pereira

josbijma · ‎12-16-2015

Hi Caio Pereira,

We are planning to use the CLKO2 Signal available on the Colibri socket.

Best regards,

Jos Bijma

caiopereira · ‎12-16-2015

Ok thank you!

I already test with CLKO2 and works fine!

I'm having problem with 12288000 Hz crystal.

Hello ,

Please find the attached file for configuration in dts file and dmesg log.

With this configuration, we are seeing dual sound card detection, but both the sound cards are failing to record the sound.

Please let us know if we are missing something in dts file.
