您好!

我使用的是基于 AM5728 SOC 的定制板。 它连接了 tlv320aic3212tlv320aic3212音频 ocodec。  

在 AM5728 EVM 中、编解码器 tlv320aic3104配置为主模式、可通过以下 DTS 文件进行验证:-

 ??Sound0:Sound0{
               兼容="简单音频卡";
               simple-audio-card、name ="BeagleBoard-X15";
               simple-audio-card、小工具=
                       "线路"、"线路输出"、
                       "线路"、"线路输入";
               简单音频卡,路由=
                       "线路输出"、    "LLOUT"、
                       "线路输出"、    "RLOUT"、
                       "MIC2L"、       "线路输入"、
                       "MIC2R"、       "线路输入";
               simple-audio-card、format ="DSP_b";
               simple-audio-card、bitclock-master =<&sound0_master>
               simple-audio-card、frame-master =<&sound0_master>
               简单音频卡、位时钟反转;

               simple-audio-card、CPU{
                       Sound-Dai =<&mcasp3>;
               };

               sound0_master:simple-audio-card、codec{
                       sound-dai =<&tlv320aic3104>;
                       时钟=<&clkout2_clk>;
               };
       };

同样、我尝试 通过如下方式更改 DTS 条目、在主模式下的自定义电路板中配置 tlv320aic3212 autocodec。

??Sound0:Sound0{
               兼容="简单音频卡";
               simple-audio-card、name ="BeagleBoard-X15";

               simple-audio-card、format ="DSP_b";
               simple-audio-card、bitclock-master =<&sound0_master>
               simple-audio-card、frame-master =<&sound0_master>
               简单音频卡、位时钟反转;

               CPU_Dai:简单音频卡、CPU{
                       Sound-Dai =<&mcasp3>;
                       时钟=<&clkout2_clk>;
               };

               sound0_master:simple-audio-card、codec{
                       sound-dai =<&tlv320aic3212>;
                       时钟=<&clkout2_clk>;
               };
       };

使用示波器进行探测时发现 未 检测到时钟信号。 但是、当编解码器配置为从模式时、会检测到时钟信号。  

 前一个问题可能是什么? 请帮助!!!

此致!
