Hi all!

I’am woking on external codec I/F with TI TLV320AIC3105.
I understood, codec need platform/machine I/F from NVIDIA_Tegra_Linux_Driver_Package doc.

so looking for source and example in R28.1(Jetpack3.1)
at NVIDIA_Tegra_Linux_Driver_Package sample DT on Tegra ASoC Driver.

I’m not sure but confusing include SDK source.
I thought that DT example is using CONFIG_SND_SOC_TEGRA_T210REF_ALT
but it not use and not exist in TX2 R28.1 SDK.
Similar using config is CONFIG_SND_SOC_TEGRA_T186REF_ALT.

It’s OK here.

Where is the source using CONFIG_SND_SOC_TEGRA_T186REF_ALT ?
match source tegra-alt-t186ref.c is not use in
./linux-l4t-4.4/kernel/t18x/sound/soc/tegra-alt/Makefile.t18x

How am i woking on my job.

Please help me!

@peter_park
I think your are talking the tegra_t186ref_alt.c
For the reference audio codec on TX2 is rt565x I think you can reference to tegra_t186ref_mobile_rt565x.c
