咨询下给位大佬一个zero摄像头的问题

xwings · 2022-06-16 11:31:33

我是用5.10的linux
在配置的时候只要勾选了，
> Device Drivers > Multimedia support > Media drivers > V4L platform devices
<*> Allwinner V3s Camera Sensor Interface driver
启动的时候就没有显示了，第一个界面可以看到logo ，然后第二个界面就不行了，慢慢的屏幕就变黑了，这个是什么原因呢

我是这样配置的
## 修改显示屏驱动方式
```
// chosen {
// #address-cells = <1>;
// #size-cells = <1>;
// ranges;

// framebuffer-lcd {
// compatible = "allwinner,simple-framebuffer",
// "simple-framebuffer";
// allwinner,pipeline = "mixer0-lcd0";
// clocks = <&display_clocks CLK_MIXER0>,
// <&ccu CLK_TCON0>;
// status = "disabled";
// };
// };

chosen {
#address-cells = <1>;
#size-cells = <1>;
ranges;

simplefb_lcd: framebuffer@0 {
compatible = "allwinner,simple-framebuffer",
"simple-framebuffer";
allwinner,pipeline = "de0-lcd0";
clocks = <&ccu CLK_BUS_TCON0>, <&display_clocks 0>,
<&display_clocks 6>, <&ccu CLK_TCON0>;
status = "disabled";
};
};
```

这样配置对不对呢？

xwings · 2022-06-27 11:47:56

荔枝派zero + 底板的是不是dvp摄像头和显示屏不能共用呢？

xwings · 2022-06-27 12:39:19

荔枝派nano可以同时使用摄像头和显示屏吗

哇酷小二说：

xwings 说：

F1C芯片可以，但是荔枝派nano可能不行。
芒果派的tiny200开发板可以同时用。

好的，感谢

还没有研究原理图,是不是脚复用的问题...
