在uboot的dts和clock dtsi里发现都没有twi相关的配置，如何在uboot下打开twi模块呢？

板端单独跑tt是没问题的，但是无法和DragonMAT连接

小机端可以跑demo-c测试软件，但是小机上好像没有aatp client，所以PC端的工具用adb -s 20080411 forward tcp:10001 tcp:8887转发tcp报文是不行的，小机上没有软件监听tcp 10001端口

@yixintai 可以裁剪的视频编码都已经裁剪了，64M内存还是很紧张，经常出现OOM问题，我们的音频解码不需要4M的，因为观察解码出来的PCM缓存，只有300多K，音频解码的StreamBuffer在我们的场景下，128K就够了的，还是麻烦尽快提供下修改方法，感谢。

hjbilly

该怎么修改呢？我还没找到修改方法

hjbilly

Audio stream buffer size:4194304, Max frame num:4096, PCM data size:328960, Stream data size:0
上面四个值是以下函数调用查询出来的，请教下，这个AudioStreamBufferSize可以改小吗？
p->AlibItf.AudioStreamBufferSize(),
p->AlibItf.AudioStreamBufferMaxFrameNum(),
p->AlibItf.AudioPCMDataSize(p->AlibItf.libadecoder),
p->AlibItf.AudioStreamDataSize(p->AlibItf.libadecoder));

使能之后报上面的错误，prebuild下没有ccache目录，该从哪里下载安装？

播放1M比特率的RTSP码流，1280x720的，15帧，播放非常卡顿，有什么优化建议么？
