完结撒花，调试到最后还是驱动问题，完成了 f1c200s tina 3.5 kernel 3.10硬件平台的xr829驱动调试，完成了wifi版本移植，踩坑了驱动移植、驱动加载不成功、扫描不到wifi、ping时间超时等一堆问题，终于爬坑成功，感谢各位大佬的支持。

下面是扫描wifi路由的结果，大概率情况下设备是一个wifi都扫描不到的，只能偶尔扫描到几个wifi。
偶尔赛秒到的几个wifi,看样子不像是硬件设计问题：

之前买的开发板
正在找这款芯片的sdk，非常感谢大佬的分享
目前insmod xr829可以正常加载了，再系统中也能正常的看到网卡设备了，但是wifi还是不能正常使用，也不知道问题出在哪里了，有大佬知道的么

合宙air780e提供的音频压缩算法库只有amr-nb算法，只支持8k 采样率的音频，已经满足不了现在的语言识别等系统中对录音采样率的要求了，于是移植了一个amr-wb音频压缩算法，支持16k采样率。移植的是定点计算版本，减少对对算力的消耗，不过从最终的测试结果来看amr-wb算法，消耗的内存空间比较小，对算力的要求比较高，实际使用只能用最低一档的码率输出。放在其他算力高一点的平台可能效果更好。以下是对应的编码库和调用demo。
