Loading sgtl5000 codec and machine driver as dynamic module

anilghadiya — Tue, 27 Jan 2015 11:31:21 GMT

Hi,

Is it possible to insert the sgtl5000 related modules as dynamic module(using "insmod").

I have build sgtl5000.c imx-sgtl5000.c and imx-audmux.c as independent module and tried to insert it, but it gives error saying as shown below...

root@nitrogen:/home/ubuntu/sgtl5000#

root@nitrogen:/home/ubuntu/sgtl5000# insmod sgtl5000.ko

root@nitrogen:/home/ubuntu/sgtl5000# insmod imx-audmux.ko

root@nitrogen:/home/ubuntu/sgtl5000# insmod imx-sgtl5000.ko

imx-sgtl5000 sound.24: ASoC: CPU DAI (null) not registered

imx-sgtl5000 sound.24: snd_soc_register_card failed (-517)

root@nitrogen:/home/ubuntu/sgtl5000# dmesg -c

sgtl5000 0-000a: sgtl5000 revision 0x11

imx-sgtl5000 sound.24: ASoC: CPU DAI (null) not registered

imx-sgtl5000 sound.24: snd_soc_register_card failed (-517)

platform sound.24: Driver imx-sgtl5000 requests probe deferral

root@nitrogen:/home/ubuntu/sgtl5000#

Am i missing anything here?..

I am able to load these modules with kernel(statically) and user the capture and playback functionality

I am using iMX-sabrelite board with kernel_3.10.17_1.0.0 SD card image.

Thanks in Advance,

Hi,

Anil

Can review your pinmux and Clocking to SGTL5000?

Thanks

Hi Saurabh,

Thanks for the reply.

I will check the clock configuration. But i am not able to understand why the same modules are working fine when i build it with the kernel.

If i enable the "CONFIG_SND_SOC_IMX_SGTL5000" then everything works fine.

With Regards,

Hi,

Anil

In this case your module initialization order needs to check.

Thanks

Do you have any idea about this.

Thanks and Regards,
