2.1 调试总览，调试步骤分析
- 步骤 ① dts配置
- 步骤 ② 编译烧写，调试
2.2 dts配置
-
系统声音配置：
es8388_sound: es8388-sound { status = "okay"; compatible = "rockchip,multicodecs-card"; rockchip,card-name = "rockchip-es8388"; hp-det-gpio = <&gpio1 RK_PD5 GPIO_ACTIVE_LOW>; io-channels = <&saradc 3>; io-channel-names = "adc-detect"; keyup-threshold-microvolt = <1800000>; poll-interval = <100>; spk-con-gpio = <&gpio1 RK_PD3 GPIO_ACTIVE_HIGH>; hp-con-gpio = <&gpio1 RK_PD2 GPIO_ACTIVE_HIGH>; rockchip,format = "i2s"; rockchip,mclk-fs = <256>; rockchip,cpu = <&i2s0_8ch>; rockchip,codec = <&es8388>; rockchip,audio-routing = "Headphone", "LOUT1", "Headphone", "ROUT1", "Speaker", "LOUT2", "Speaker", "ROUT2", "Headphone", "Headphone Power", "Headphone", "Headphone Power", "Speaker", "Speaker Power", "Speaker", "Speaker Power", "LINPUT1", "Main Mic", "LINPUT2", "Main Mic", "RINPUT1", "Headset Mic", "RINPUT2", "Headset Mic"; pinctrl-names = "default"; pinctrl-0 = <&hp_det>; play-pause-key { label = "playpause"; linux,code = <KEY_PLAYPAUSE>; press-threshold-microvolt = <2000>; }; }; -
ES8388设备驱动配置
&i2c7 { status = "okay"; es8388: es8388@11 { status = "okay"; #sound-dai-cells = <0>; compatible = "everest,es8388", "everest,es8323"; reg = <0x11>; clocks = <&cru I2S0_8CH_MCLKOUT>; clock-names = "mclk"; assigned-clocks = <&cru I2S0_8CH_MCLKOUT>; assigned-clock-rates = <12288000>; pinctrl-names = "default"; pinctrl-0 = <&i2s0_mclk>; }; };
2.3 编译烧写，调试
-
查看声卡命令：
cat /proc/asound/cards -
将wav文件拷贝到板子上：
adb root adb remount adb push C:\adb\test.wav mnt -
RK Android 播放音乐 ( RK Android SDK 标配 tiny-alsa 工具 ):
adb shell cd /mnt tinyplay ./test.wav -D 0 -d 0 -
RK Android 录音：
tinycap /sdcard/test.wav 播放录音 cd /sdcard tinyplay ./test.wav -D 0 -d 0 -
RK Linux 播放音乐 （ RK Linux SDK 标配 alsa-utils 工具 ）
aplay test.wav或者
aplay -Dplughw:0,0 test.wav aplay -Dplughw:1,0 test.wav aplay -Dplughw:2,0 test.wav -Dplughw:x 表示指定第几个声卡或者文章来源：https://www.toymoban.com/news/detail-615888.html
aplay -D plughw:CARD=rockchipes8388 test.wav -
RK Linux 录音文章来源地址https://www.toymoban.com/news/detail-615888.html
arecord -D hw:1,0 -d 10 -f cd -r 44100 -c 2 -t wav test.wav -d 10表示录制10秒声音，test.wav是保存的文件名称 -D hw:x 表示指定第几个声卡 -r 指定采样率，-f 指定每个采样点的位数--样本大小
