1. 这个问题是出在哪里了？内核么？

2. @傅伟清 已经放弃了，用tinyalsa可以了么，意思是alsa在这个nano上不行，还是哪里不对？

我发现他的设备树里有codec相关的，suniv-f1c500s-miyoo.dts
&codec {
status = "okay";
};

而我当前板子里的dtb里面没有codec相关，可能是这个原因么？

我把dtb转为dts，dtsi会全部展开，里面并没有codec，

对就是这个，不过得研究一下源码，我编译成ko后，安装老是出错

这是tina的声卡开机日志，司徒的手撸的，没深入研究过，而且没法直接上100s的

\f1c500s_kernel\sound\soc\suniv\下面，他自己写了几个文件：

感觉只是编译ko不行吧，我猜测的，
你也是用在f1c100上么？
是不是500s和100s的codec的寄存器不一样，miyoo.c代码需要修改呢？

@kekemuyu 老兄，你安装出错，错误是啥？ 是不是自动创建设备节点的时候错了？

最近编辑记录 大帅 (2019-10-28 15:19:29)

可以看下这个 https://whycan.cn/t_2041.html

求一份nes移植教程，为什么我老是报错那个声卡
