索尼Spresense“audio_manager”断言失败了

Question

我正在研究一个Spresense项目，但我的音频再现有问题。 SD卡有三个名为“1.mp3”，“2.mp3”和“3.mp3”的文件，但是当我调用其中一个时，串行发出错误并且电路板停止。

其他音频示例也适用于我的项目中实际使用的文件（重命名）

void Play(int id){
  // Open file placed on SD card
  if(id == 1){
    Serial.println("Required file 1");
    myFile = theSD.open("1.mp3");
  }
  if(id == 2){
    Serial.println("Required file 2");
    myFile = theSD.open("2.mp3");
  }
  if(id == 3){
    Serial.println("Required file 3");
    myFile = theSD.open("3.mp3");
  }

  // Verify file open
  if (!myFile)
    {
      Serial.println("File open error");
    }
  // Send first frames to be decoded
  err_t err = theAudio->writeFrames(AudioClass::Player0, myFile);
  if ((err != AUDIOLIB_ECODE_OK) && (err != AUDIOLIB_ECODE_FILEEND))
    {
      Serial.println("File Read Error!");
      myFile.close();
    }
  theAudio->startPlayer(AudioClass::Player0);
}

要分析堆栈转储，Spresense完整SDK提供了一个工具，您可以在其中指定两个文件作为参数。一个是您保存的日志文件，另一个是系统映射文件。这样做你应该能够获得堆栈跟踪。如果您使用Arduino IDE构建软件，您应该能够在Arduino IDE日志窗口中找到您的地图文件所在的位置。转到文件 - >首选项 - >设置 - >显示详细输出并选择编译，在构建草图时，您应该能够找到构建文件夹的位置。通常这个文件夹位于/ tmp中，看起来像这样：

/tmp/arduino_build_724727/

从github获取完整的SDK：

git clone --recursive [email protected]:sonydevworld/spresense.git

将目录更改为SDK：

$cd spresense/sdk
spresense/sdk$ ./tools/callstack.py -h
Usage: python ./tools/callstack.py <System.map> <stackdump.log>

现在只需指定文件的位置：

./tools/callstack.py /tmp/arduino_build_724727/output.map stackoverflow.log
