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";
