audio - Sony Spresense “audio_manager”断言失败

我正在做一个Spresense项目，但是音频再现有问题。
SD卡具有三个名为“1.mp3”，“2.mp3”和“3.mp3”的文件，但是当我调用其中一个时，Serial会出现错误，并且板卡会暂停。

其他音频示例也可以很好地与项目中实际使用的文件配合使用(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);
}

最佳答案

为了分析堆栈转储，Spresense full 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，您应该能够获取堆栈跟踪。
如果您使用Arduino IDE构建了软件，则应该能够在Arduino IDE日志窗口中找到 map 文件所在的位置。
转到"file"->“首选项”->“设置”->“在此期间显示详细输出”并选择“编译”，然后在构建草图时应该可以找到构建文件夹的位置。通常，此文件夹位于/ tmp中，如下所示:

/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
