Other Parts Discussed in Thread: AM6252, SK-AM62B-P1
Hi, experts
Hello, I have a question regarding the AM6252 custom board and Audio.
I created a custom board by modifying the circuit using the SK-AM62B-P1 base and installed AM6252.
The same IC (TLV320AIC3106IRGZT) as the EVM is used, but the MONO pin output connection is used to output a single speaker after the audio amp through the TPA3111D IC. The circuit diagram is as follows.
MONO_LOUT is connected to INN, INP pin in TPA3111D.
Please let me know how to set "simple-audio-card,routing" in device tree.
My code is below.
codec_audio: sound {
compatible = "simple-audio-card";
simple-audio-card,name = "AM62x-SKEVM";
simple-audio-card,widgets =
"Headphone", "Headphone Jack",
"Line", "Line In",
"Speaker", "Speaker External",
"Microphone", "Microphone Jack";
simple-audio-card,routing =
"Headphone Jack", "HPLOUT",
"Headphone Jack", "HPROUT",
"LINE1L", "Line In",
"LINE1R", "Line In",
"Mono Out", "MONO_LOUT",
// "Amplifier", "MONO_LOUT",
// "Speaker External", "Amplifier",
//"Speaker", "SP_AMP OUTL",
"MIC3R", "Microphone Jack",
"Microphone Jack", "Mic Bias";
simple-audio-card,format = "dsp_b";
