IMX6Q android OV3640摄像头调试

只看该作者 · 2016-8-10 17:50

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

想把拍照改成640*480分辨率，但是没有效果，代码看的不是很懂，求指点，谢谢！
