我有一个简单的波形，可以对音频流进行编码和解码（用于测试的环回）。编码器和解码器组件具有softpkg依赖性。我只能使用x86机器的GPP设备启动此波形。我已经使用为另一个实现正确配置的spd.xml交叉编译了所有deps和组件（使用armv7l处理器的cpp_arm）。 当我尝试使用在域中注册的Arm GPP设备启动此波形以运行编码器和解码器组件时..我得到以下内容：
Failed to create application: codec_loopback_234_112125459 Failed to satisfy device dependencies for component: 'Decoder' with component id: 'Decoder_1:codec_loopback_234_112125459_1'

GPP processor_name不匹配：
