RV1126B Linux6.1 kernel 设备树分析

2026-03-27 22:01:22

我现在手中有2块1126B的板子，一块是小宇智联的，一块是正点原子的

小宇智联的硬件接口如下图所示：

下面来分析小宇智能sdk中内核的相关设备树部分：

主要包括上面这几个文件，其中可以分为下面的这及部分功能：

1：电源拓扑图

2. 显示模块（DSI 屏 + 背光）

3. 摄像头模块（IMX415 完整链路）

4. 音频模块

5. 输入与基础外设

6. 多媒体 / 网络 / 存储 / USB

前面已经在小宇智联的板子上调试通过了SC233HGS

后面会使用dvp接口再调试SC035HGS,sensor已经到手：
