Re: 5.2内核找不到声卡,设备树有问题吗?

1. 驱动勾选了  "allwinner,sun8i-v3s-codec",  "allwinner,sun8i-v3s-codec-analog" ?

2. dtb确实用 sun8i-v3s-licheepi-zero-dock.dtb

3. 没烧错文件?kernel的编译日期是不是最新的?

4. 如果上面都没有问题, 就去驱动的 init( ) 函数里面加点调试代码。

dtsi里面status="disabled"
这个地方会不会有点问题?

JasonWoo 说:

codec应该在sun8i-v3s-licheepi-zero-dock.dts 里被设置成 status="okay"了,应该不是这个问题。

&codec {
	allwinner,audio-routing =
		"Headphone", "HP",
		"Headphone", "HPCOM",
		"MIC1", "Mic",
		"Mic",  "HBIAS";
	status = "okay";
};

驱动勾选了  "allwinner,sun8i-v3s-codec",  "allwinner,sun8i-v3s-codec-analog" ?

dtb用的是 sun8i-v3s-licheepi-zero-dock.dtb,kernel反复烧写过很多次,声卡始终找不到,不知道啥原因?

5.2内核有适配过声卡吗?我看5.2的内核驱动跟4.13不一样,目前4.10 4.13都能找到声卡,5.2不行,不知道哪里导致的。
