Hi All,
Can someone please share me the custom audio cape supported in beaglebone
black Rev C board.
if anyone have the picture for the custom audio cape board please share
that image.
Along with please share the schematic and datasheet for corresponding.
What will be the kernel driver for
Hi Prakash,
I've the same problem with custom audio cape.
Have you a solution now?
thanks
regards

What happens when you try the CircuitCO audio cape?
Does it work fine?

How I can check this two things ?

Hi,
Here CircuitCo cape is not available So we decided to make our own.

Hi Maxim ,
I try with your suggestion of aplay -vv test.wav But still same things.
Please find attachment of dmesg log.
Hope listen from you soon. :)
Thanks Regards,

OK, and what is different between your board and CircuitCo schematic wise?

Schematic wise both are same.

Hi,
I have made custom Audio cape using TLV320AIC3107. Here is a circuit
diagram :

I make it same ( Pin configurations and all ) as what is available at
CircuitCO using
Have you config the i2c pin pulled up ?
and
whats the speed of your i2c bus ?

I'm very interested in how you would solve this issue. We are having a
similar problem with a basic AIC3104 codec and no idea how to debug the
situation.

Definitely it's a problem with the i2c lines, cross check your connections
with i2c lines or as suggested above to check the pullups. Issue the
following command to see if the chip is detected on the i2c bus or not -
i2cdetect -y -r i2c_bus_no

frequency of i2c bus as specified in dts is 100 kHz.

Hi,
I think in Device tree, i2c pin is pulled up. here is part of Tree.
i2c2_pins: pinmux_i2c2_pins {
pinctrl-single,pins =
0x150 0x72 /*spi0_scl.i2c2_sda,SLEWCTRL_SLOW | INPUT_PULLUP |MODE2*/
0x154 0x72 /*spi0_d0.i2c2_scl,SLEWCTRL_SLOW | INPUT_PULLUP | MODE2*/
;
};

1) change 10k pull-up resistors to 5.6k as for other capes
2) check if SYS_RESET is actually deasserted and high
3) check if DIN/DOUT are correctly connected and not flipped, because DIN
data must go into CODEC, while DOUT must go out and vise versa
use this command to test (not speaker-test).
HI,
Thanks For reply.
Can you please tell me how I can Do that ?
Thanks Regards,

what is exactly not clear for you?
how to change resistors or how to copy/paste commands in a shell?

I'm not clear about this. Actually I have two Boards one with 10K
