Other Parts Discussed in Thread: AM3352, TPS65217
Tool/software: Linux
Hi,
I am working on a TI's customized board using SDCard for booting and ti-processor-sdk-linux-am335x-evm-03.02.00.05-Linux-x86-Install as SDK.
On using "aplay" command, I got the following error.
root@ngt:~# aplay audiocheck1.wav
aplay: /usr/lib/libasound.so.2: no version information available (required by aplay)

Further, I checked snd_soc_tlv320aic3x module and removed it and got the following error.

The codec device was at adress 0x1b, but after removing snd_soc_tlv320aic3x "rmmod snd_soc_tlv320aic3x", I'm expecting i2c address of codec to be shown instead of UU. But we are not getting anything on that i2c bus.
Changes Done
I have registered the tlv320aic3106 in the device tree as shown below:

Please suggest how that i2c error and unable to sync registers error can be solved?
Thanks and Regards
