[Fireprime]ov5640 camera is not working

jaymoon

Hi,

I have a problem using ov5640 camera module with FireprimeS board.

I have got the debugging message like these:

[    1.563568] rk818_ldo8: disabling
[    1.564487] rk818_ldo4: disabling


I think ldo8 and ldo4 are needed for the power of this camera module.

I have changed the code, "rk3128-cif-sensor.dtsi" as follows:

             ov5640{
                        is_front = <0>;
                        rockchip,powerdown = <&gpio3 GPIO_D7 GPIO_ACTIVE_HIGH>;
                        pwdn_active = <ov5640_PWRDN_ACTIVE>;
                        #rockchip,power = <1>;
                        pwr_active = <PWR_ACTIVE_HIGH>;
                        #rockchip,reset = <>;
                        #rst_active = <>;
                        #rockchip,flash = <>;
                        #rockchip,af = <>;
                        mir = <0>;
                        flash_attach = <0>;
                        resolution = <ov5640_FULL_RESOLUTION>;
                        powerup_sequence = <ov5640_PWRSEQ>;
                        orientation = <0>;
                        i2c_add = <ov5640_I2C_ADDR>;
                        i2c_rata = <100000>;
                        i2c_chl = <0>;
                        cif_chl = <0>;
                        mclk_rate = <24>;

                   }

            I got some patch information from this site. I did it already. But I can't solve this problem.
            The patch files are  0001-kernel-camera-fix-cif-controller-capture-problem.patch and
               0002-kernel-camera-fix-queryctrl-framesizes-frameinterval.patch.

Please help me...

Thank you

Thank you for helping me.

I did patch all codes.But it's still not working.  
[    1.581575] rk818_ldo8: disabling
[    1.582497] rk818_ldo4: disabling
the CIF connector uses these ldo8and4 for camera power?
So, it must have the ldo power? am I right?

What's that mean, the reverse rule, reset?
I used it the following code for resetting changing the LOW and HIGH, all cases
But it didn't work.
                        if(ov5640_io == 1){
                             rst = of_get_named_gpio_flags(cp, "tchip,rst", 0, &rst_flags);
                            gpio_request(rst, "tchip,rst");
                            printk("rst = %d\n", rst);
                             gpio_direction_output(rst,GPIO_LOW); //GPIO_HIGH
                             msleep(20);
                             gpio_direction_output(rst,GPIO_HIGH); //GPIO_LOW
                             ov5640_io = 2;
                     }


Thank you

Hi,

We used other power sources for the camera.

So, it is OK for I2C register setting.
And  it works.

But we got the green screen when we clicked the Camera button.

log message is as follows:

I need some comment about this.

Please help me,

Thank you
