imx6q two cameras(mipi ov5640 and csi ov5642) work at the same time

[luciuslu]

hi  all,

now I am debugging the cameras driver in the platform of imx6q_sabreSD and the kernel is "linux-imx6-boundary-imx-3.0.35_4.0.0-vivante-4.6.9p12". I encountered a problem :i can capture image independently well (either mipi ov5640 or csi ov5640).but the both cameras cannot work simultaneously.

my i2c register is as follow:

1.

static struct i2c_board_info mxc_i2c0_board_info[] __initdata = {

 {

  I2C_BOARD_INFO("ov564x", 0x3c),

  .platform_data = (void *)&camera_data,

 },

...

};

2.

static struct i2c_board_info mxc_i2c1_board_info[] __initdata = {

 {

  I2C_BOARD_INFO("ov5640_mipi", 0x3c),

  .platform_data = (void *)&mipi_csi2_data,

 },

 ...

}

so there is no conflit on i2c pipeline.

I don't know where the problem is?

I beg someone can give me a solution,a patch or where to fix the problem!

best regards!

by the way, if it is possible,I would like to configue like this: csi OV5642 -IPU0-CSI0 and MIPI OV5640-IPU1-CSI1.

Now the  Circuit schematic connection as follow:

OV5642 (parallel data interface) to CSI0 and OV5640 (MIPI) to CSI1.

I want use two IPUs,not only one.

I beg someone help me,When it's over, I would like to treat you to dinner!haha.

BestRegards!

Hi lucius

please look at example how to assign cameras to different IPU CSIx (VCn)

hi igorpadykov

thanks for your quick respond!

but your recommendation is other kernel version,my kernel version is 3.0.35,there is no .dts or .dtsi in imx-3.0.35_4.0.0,so I donot know how to modify it correspond other version which has dts .

Look forward to your reply!
