TAS2110: Unable to play wav files through aplay

Michelin Wu
Prodigy 20 points
Part Number: TAS2110

Tool/software:

I cannot play the sound effect file through aplay.


The error message is as follows:

I can find the device:

Device Tree:

audio_amp: tas2562@4c {
	#sound-dai-cells = <0>;
	reg = <0x4c>;
	compatible = "ti,tas2562";
	interrupt-parent = <&gpio4>;
	interrupts = <28>;
	shutdown-gpios = <&gpio4 29 GPIO_ACTIVE_HIGH>;
	ti,imon-slot-no = <0>;
	ti,vmon-slot-no = <1>;
	status = "okay";
};

&sai3 {
	#sound-dai-cells = <0>;
	pinctrl-names = "default";
	pinctrl-0 = <&pinctrl_sai3>;
	assigned-clocks = <&clk IMX8MP_CLK_SAI3>;
	assigned-clock-parents = <&clk IMX8MP_AUDIO_PLL1_OUT>;
	assigned-clock-rates = <12288000>;
	status = "okay";
};

How can I play the sound?

Thanks

    I refer to section 8.5.7 in the document "TAS2110 6.1-W Digital Input Audio Class-D Amplifier With Integrated 11-V Class-H Boost" (SLASET8–DECEMBER 2019).

    I set register "page=0x00 address=0x02 value=0x00 " (MODE[1:0] equals "00b = Active"), and the result value is always 0x02.

    Is this the reason why wav files cannot be played?

    Please tell me how to solve it, thank you.

    Hi,

    If register 0x02 goes always back to 0x02, means the device is shutting down itself due to some error.
    Register 0x24 shows value of 0x04, which means TDM clock error. Please make sure you enable the device through register 0x02 only after the input clocks are up and running. Enabling the device without input clocks will cause the device to shutdown automatically.
