Hi,
Thanks for reply.
The pullup resistor which is using in I2C Bus is 10K with 3.3V.

What size pullup resistors are you using on the I2C bus?

Hi,
You are right. I have 4 PCA8574T I/o Expander chip.

So it appears you should expect to see a device between 0x20 through 0x27
from the datasheets. The device address is 0*010* when not shifted
for the R/W bit. That
frequency of i2c bus as specified in dts is 100 kHz.

whats the speed of your i2c bus ?

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*/
;
};

Hi,
How I can check this two things ?
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
I'm not clear about this. Actually I have two Boards one with 10K
Hi,
Here CircuitCo cape is not available So we decided to make our own.

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

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,

Hi,
Schematic wise both are same.

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

Hi John,
I have made custom audio cape using TLV320AIC3107 codec and here is a
schematic diagram.
