Other Parts Discussed in Thread: DM3730

Hi all;

      i'am just a starter ,we want to drive the MT9D131 on dm3730(devkit8500 board) . We use the ov3640.c that exists and modify it.  But we got incorrect data like the  attachment. Can anybody point me ? 

     We fill some ioctl for v4l2 ,is something wrong with the register? thank you!


Regards,

Jerry

    Hi Jerry,

    I see only noise on the attached picture. It is very possible to have some wrong settings in the driver. I'm not excluding hardware problem with the sensor but it is unlikely. 

    I recommend you to check the initialization description in the datasheet of MT9D131.
