Hello!
I want to add Texas Instruments TAS5722 audio chip for TX2NX but I can’t seem to find any guides how to do it properly.
So far I have done this:
- Connected I2S and I2C to TX2NX (Supply pins for now I’m getting from power supply)
- Added TAS5722 driver and compiled kernel with it and flashed the kernel
- Enabled I2S1 in DeviceTree
- Added chip to DeviceTree (there are no DVDD and PVDD supplies, because I have my own from PSU and I have commented out getting/setting the power for the chip, it’s always on):
i2c@c240000 {
tas5722: tas5722@6c {
compatible = "ti,tas5722";
reg = <0x6c>;
};
};
The driver probes sucessfully, registers the codec but after that literally nothing happens. How can I even debug things like this?
In alsamixer it just shows that the card is tegra-snd-t186ref-mobile-rt565x and no chip. What else do I need to do in order to enable my audio chip?
