sgtl5000 not found on mx6q

[xiaoqiangyang]

Hi all,

Now I am working on new designed i.MX6Q board.The BSP is L3.0.35_4.1.0_130816.

We added codec SGTL5000 and the code is ported from sabrelite.But the chip can

not be probed by kernel.MCLK is indeed 24Mhz,and VDDA-3.3V,VDDIO-3.3V,VDDA-1.8V.

Kernel config:

CONFIG_SND_SOC_IMX_SGTL5000=y

CONFIG_SND_SOC_SGTL5000=y

During boot up my oscilloscope can not get the i2c(i2c1 bus) signal.Under linux,

I use i2cdetect tool,only the PFUZE100(08) can be found,like this:

root@linaro-ubuntu-desktop:~# ./i2cdetect -y 0

0 1 2 3 4 5 6 7 8 9 a b c d e f

00: -- -- -- -- -- 08 -- UU -- -- -- -- --

10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

70: -- -- -- -- -- -- -- --

But if I deleted the code for i2c information :

static struct i2c_board_info mxc_i2c0_board_info[] __initdata = {

{

I2C_BOARD_INFO("sgtl5000", 0x0a),

},

}

After entering linux,i2cdetect tool can find it-->

0 1 2 3 4 5 6 7 8 9 a b c d e f

00: -- -- -- -- -- 08 -- 0a -- -- -- -- --

10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

70: -- -- -- -- -- -- -- --

So strange, why it can be probed if I don't register it?

Any advice will be appreciated.

Best Regards

Hi Xiaoqiang

I think your codec chip is properly registered and

I believe this is why you are seeing UU under

0xa0.

You mentioned that the chip can not be probed

by the kernel. How do you see this ? What are

the related kernel messages ?

In any case, the best way to debug your chip

is to check the mclk, frame clock and data

using an oscilloscope.

Include here the kernel messages if you see

any error during the probe. Likewise, you might

want to add more debug printk's to see what

is failing.

Hope this helps

Hi Sinan,

Thanks for your reply.Because I can't see any message of sgtl5000 during boot up,

and I use aplay -l command it shows :

aplay: device_list:240: no soundcards found...

cat /proc/asound/card:

--- no soundcards ---

this is my boot log --->

Hi Xiaoqiang

I see the following error message in the boot log :

imx-hdmi-soc-dai imx-hdmi-soc-dai.0: Failed: Load HDMI-video first.

It seems as if you enabled hdmi but not sgtl5000 as your sound card.

I suggest, you take a look at your kernel config and make sure

sgtl5000 is enabled and hdmi is disabled under the list of sound

cards. Likewise, add some debug printks in the probe function

of the driver and see if it is called at all.

Hope this helps

Hi Sinan,

My problem has been solved. It is in imx-sgtl5000.c...>

if (machine_is_mx35_3ds() || machine_is_mx6q_sabrelite())

        imx_sgtl5000_dai[0].codec_name = "sgtl5000.0-000a";

else

        imx_sgtl5000_dai[0].codec_name = "sgtl5000.1-000a";

Becsuce my machine is mx6q_sabresd, so sgtl5000 is on bus 1 defaut, my sgtl5000 is on bus 0 ,so I changed it to sgtl5000.1-000a and now it works well.

Thanks a lot!
