Error happesn when using 4 1280x800 cameras at same time

[yafengge126]

你好，liqiang

同时打开4个1080x800的ov摄像头，streem on调用失败（调用接口 ioctl (m_iV4L2DevID, VIDIOC_STREAMON, &type)）；

并在驱动中提示下面的错误（注：单独打开一个没错误）;

How do you setup the I2C for 4 cameras?

How do you connect 4 cameras to i.MX6D?

which BSP are you using?
