Part Number: PCMD3140EVM-PDK
Other Parts Discussed in Thread: TLV320ADC3140

Hi ti team.

I use "git.ti.com/gitweb library for setup card driver. But it's for beaglebone black card.

I did many steps and compiled kernel with files.

But i have problem from dts file.

https://git.ti.com/cgit/lpaa-android-drivers/tac5x1x-linux-driver/ This is for raspberry pi 4 but I couldn't prepare dts file.

So I need tlv320adc3140 overlay dts file for raspberry pi 4. Also raspberry pi 4 uses bcm2711-rpi-4-b.dts.

I suggest to use this code

src - lpaa-android-drivers/pcmdevice-linux-driver - Unnamed repository; edit this file 'description' to name the repository.

DTS example:

genericstereoaudiocodec.dts « doc - lpaa-android-drivers/pcmdevice-linux-driver - Unnamed repository; edit this file 'description' to name the repository.

Guideline:

git.ti.com/cgit/lpaa-android-drivers/pcmdevice-linux-driver/plain/doc/Guideline for PCMDEVICE driver on Linux.pdf

json file:

jsn - lpaa-android-drivers/pcmdevice-linux-driver - Unnamed repository; edit this file 'description' to name the repository.

regbin tools and guideline:

tool - lpaa-android-drivers/pcmdevice-linux-driver - Unnamed repository; edit this file 'description' to name the repository.

I used GitHub - AkiyukiOkayasu/RaspberryPi this file for i2smaster dts. And i finally get voice from card. But it just work for 2 channel. How can i get 4 channel with tdm format.

Hi Ulas

first you will confirm whether raspberry support tdmmaster?

If not, you will confirm whether raspberry support tdmslave?

if it can, you will set tlv320adc3140 as tdm master, and set raspberry as tdm slave in device tree.

If raspberry support neither tdmmaster nor tdmslave, you may as well select other platform which support tdm.
