Hi, I have made custom Audio cape using TLV320AIC3107. Here is a circuit diagram :
<http://e2e.ti.com/cfs-file.ashx/__key/telligent-evolution-components-attachments/00-64-01-00-01-29-55-62/audio.png> I make it same ( Pin configurations and all ) as what is available at CircuitCO using TLC320AIC3104 codec. I follow All steps like Disable HDMI and Load Device Tree BB-BONE-AUDI-02-00A0.dts and I it works fine. But my problem is when I run speaker-test system hangs (freezes) and I have to Hard Reset BeagleBone. Here is what i did and what I get in dmesg. *root@beaglebone:~# speaker-test * speaker-test 1.0.25 Playback device is default Stream parameters are 48000Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 128 to 32768 Period size range from 8 to 2048 Using max buffer size 32768 Periods = 4 *And in Dmesg : * [ 205.540653] omap_i2c 4819c000.i2c: Arbitration lost [ 206.572921] omap_i2c 4819c000.i2c: controller timed out [ 206.580024] omap_i2c 4819c000.i2c: Arbitration lost [ 207.611983] omap_i2c 4819c000.i2c: controller timed out [ 207.618668] omap_i2c 4819c000.i2c: Arbitration lost [ 212.626062] omap_i2c 4819c000.i2c: Arbitration lost [ 213.658853] omap_i2c 4819c000.i2c: controller timed out [ 213.666881] omap_i2c 4819c000.i2c: Arbitration lost [ 214.699867] omap_i2c 4819c000.i2c: controller timed out [ 214.707912] omap_i2c 4819c000.i2c: Arbitration lost [ 215.740887] omap_i2c 4819c000.i2c: controller timed out [ 215.748952] omap_i2c 4819c000.i2c: Arbitration lost I also cross check device tree file and I found that it also works for TLV320AIC3107 codec So I think it is not issue.
