用附件替换掉hardware/rk29/camera/SiliconImage/isi/drv/OV13850/source/OV13850_tables.c试试
为什么不能下载啊 大神们 我也遇到这个问题了

用的firefly8.1的sdk，sensor是ov13850,摄像头没有图像。想问题一下我这个是什么情况呢？？？ 大佬，已经解决了吗？

我也遇到这个问题了

你这个I2C都没通，估计是power on ，power off， reset脚没有配置对。确认一下啊IO引脚是不是配对先 楼主好！
我的ov13850日志里记录：
ov13850 1-0010: driver version : 00.01.01
ov13850 1-0010: could not get module information!
.....
ov13850 1-0010: Detected ov00d850 sensor, revision 0xb1
ov13850 2-0010: driver version : 00.01.01
ov13850 2-0010: could not get module information!
.....
ov13850 2-0010: Unexpected sensor id(000000), ret(-5)
后面部分（2-0010）是怎么回事呢，我的摄像头能打开显示图像，不过在分辨率高的情况下打开后关闭容易出现卡死问题，与上面的日志有什么关系吗？
