/dev/camsys_marvin & /dev/camsys_marvin1 on Ubuntu

santo4ul

Hi,

    I'm using Ubuntu and trying to read frames from two cameras (OV13850 board) connected to MIPI-CSI ports. From what I understand, it is not supported yet in Ubuntu.

    On the Android SDK, I see the two cameras are exposed as /dev/camsys_marvin and /dev/camsys_marvin1. The same marvin driver used in Android is also seen under Ubuntu Linux kernel source code.

    What I believe is missing in Ubuntu are the relevant DTS changes to enable the mipi-csi/isp/marvin. Android or Ubuntu, it is still Linux kernel and I belive bringing-up /dev/camsys_marvin and /dev/camsys_marvin1 on Ubuntu must be straight forward.

    Is my understanding correct? Could someone throw some light?


Thanks,
San

I got many compile errors while trying to make menuconfig with built-in marvin isp as it pointed in official instruction.

I am very dissappointed. Moreover, I can't run Cheese because of rockchip_dri.so error and can't set webcam auto_gain parameter via v4l2_ctl - libwebcam error.
