详细说明： R58点亮ov2640.txt 开发板：全志公板，全志R58（CPU：Octa-Core Cortex-A7 CPU） http://www.allwinnertech.com/clq/r/R58.html 全志官网R58的简介 android4.4.4/linux3.4.39 2016/6/30 9:36 1、配置ov2640在android层配置的分辨率为vga（预览/拍照/录像） 注意：系统自带的快拍APP就在这里查找分辨率参数发送到camera的HAL层。 cubieboard2开发板使用的是全志A20 的CPU，自带两路CSI的摄像头接口。 一般使用CSI1，所有生成的设备节点是/dev/video1。 一般情况下，MIPI为主摄像头（后置摄像头），那设备节点就是/dev/video0。 没有接MIPI摄像头，那就空出来，像全志A20那样配置成为了/dev/video1了。结果被坑了。 后来想起来： insmod /system/vendor/modules/ov2640.ko insmod /system/vendor/modules/vfe_v4l2.ko 手工加载vfe_v4l2.ko驱动模块之后，生成了设备节点/dev/video0。 赶紧修改为/dev/video0。然后使用adb push进去。 修改属性之后，摄像头还是不显示。重启之后正常了。这里折腾了好久！！！！ R:\wyb\p720_ov2640_r58_dev\android\device\softwinner\octopus-f1\configs\camera.cfg ;------------------------------------------------------------------------------- ;
