TI中文支持网我这边用的psp是 PSP 04.02.00.07,Linux版本用的是TI的2.6.37
仿照mt9t111摄像头驱动写ov3640的驱动,ov3640电源和i2c操作都正常,能获取到sensor的id号
我遇到的问题是用saMmapLoopback测试,
log如下

请帮忙分析是哪里出了问题,我该如何添加ov3640到我的项目才能正常工作
echo zhang：
补充下,我现在用的项目是没有tvp514x芯片的,是ov3640直接接到3715的camera接口的

这个是测试程序没有修改显示的测试log

回复 echo zhang:
你好，您的问题解决了吗，现在我们也在采用这种直接连到camera口的方案，还没有思路，能否指点一下。谢谢
