Part Number: AM3352
Other Parts Discussed in Thread: TLV320AIC3204, , TLV320AIC3106
Tool/software: Linux
Dear TI Team,
We are design a AI Smart Speaker project. We are used AM3352 and TLV320AIC3204 parts on our boards. We are used Kernel version at 4.4.30 and added "CONFIG_SND_SOC_TLV320AIC32X4" for TLV320AIC3204 audio on defconfig file and build into kernel driver( not kernel module). Beside that, I revise DTS file to integrate it to ALSA audio-simple-codec. Attached below is my dts file.
- After booting, I type "aplay -l" command, log is:
root@beaglebone:~# aplay -l
aplay: device_list:268: no soundcards found...
- Dmesg | grep tlv to see log:
[ 2.327225] tlv320aic32x4 1-0018: Failed getting the mclk. The current implementation does not support the usage of this codec without mclk.
I also try passing this error by using patch file at the link: http://mailman.alsa-project.org/pipermail/alsa-devel/2015-June/094297.html. But, it seems to not be working for this case.
- Could you help to answer my question as below:
+ How can I enable tlv320aic32x4 driver in kernel source?
+ The DTS file is so important. Can you give me some examples of writting DTS file to resolve this problem?
