环境:
IMX6Q android OV3640摄像头

现象:
640*480全景拍照正常,1280*720录像功能正常,2048*1536分辨率拍照花屏,

修改过程:
ov3640.c驱动文件,寄存器设置修改过,拍照还是花屏
HAL层代码,对比过TQ和飞凌的代码,差别不大。

部分源码见附件

接楼上,补充。可以交换IMX6Q android驱动资料,LVDS、TP、SD、USB、音频、网卡、串口、CAN、RS485、VGA、HDMI、WIFI+BT等驱动多已经调通了。可以交换其中一个驱动资料。谢谢!我的邮箱 543027657@qq.com

低分辨率已经正常, 高分辨率却花屏, 我想这应该有两个可能因素
1. 配置问题, 设置错误, 可以再仔细检查一下
2. 数据带宽限制, 高分辨率下数据量明显提高, 如果来不及采样和接收, 那么必然错误或花屏. 看看你的数据贪吐能力, 有没有使用 DMA, 或者也可以实际测试一下这个能力

楼主的问题解决了吗?
  另外,我们的方案里有3个摄像头,用第三方APP做直播,时间稍微长了,切换摄像头就卡在原来的画面。

用了MIPI摄像头了?

比如这样:
  [    3.005410] camera ov5640_mipi is found.
