你好!

          imx6DQ 移植xc7160外置isp +  imx298 sensor,可见光滚屏,

   正常成像:pastedImage_6.png

   滚动异常成像如下:

pastedImage_5.png

         更详细的滚动现象见附件video

           android版本 6.0.1

          kernel版本 4.1.15-g78b8542

          camera通道配置如下:

                  ipu_id = <0>;
                  csi_id = <1>;
                  v_channel_id = <1>;

                  80M pclk,4 lanes

         出现滚屏现象时,读取MIPI_CSI_ERR1寄存器值等于0x20020000

         根据 IMX6DQRM.pdf手册查到对应以下错误:

 pastedImage_3.png

         请帮忙分析什么原因造成成像滚动的

         谢谢!

This issue may due to different reasons. e.g. the incorrect resolution or incorrect capture data format.

For your reference, this is an experience of porting a camera.

Attached is a porting guide. You can read the Chapter 7 about how to porting a camera.

图像格式是UYVY是正确的,分辨率1280x720的,这种滚屏是随机出现的,有没有可能与sensor到主板的连接线有关?
