Use adv7180 on i.mx6q fail

[zoechen]

Hi All,

     I use adv7180 on i.mx6q with Android KK BSP. When I want to preview it will log "ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0", the parameter as follow:

preview size : 720 x 576

std:               PAL

format:          V4L2_PIX_FMT_NV12

check the single from oscilloscope, the CVBS line , csi0 data line, csi0 vsync , csi0hsync all have single, but it seem that csi0 host port don't receive any data from ADV7180.  Who can tell me how to debug it ?

This is our debug log :

This is my code, please help to check:

static void adv7180_pwdn(int pwdn)

{

    if (pwdn)

        gpio_set_value_cansleep(BUS_ADV7180_PWN_EN, 0);

    else

        gpio_set_value_cansleep(BUS_ADV7180_PWN_EN, 1);

}

static void mx6q_csi0_io_init(void)

{

    if (cpu_is_mx6q())

        mxc_iomux_v3_setup_multiple_pads(mx6q_sabresd_csi0_sensor_pads,

            ARRAY_SIZE(mx6q_sabresd_csi0_sensor_pads));

    else if (cpu_is_mx6dl())

        mxc_iomux_v3_setup_multiple_pads(mx6dl_sabresd_csi0_sensor_pads,

            ARRAY_SIZE(mx6dl_sabresd_csi0_sensor_pads));

    if (cpu_is_mx6q())

        mxc_iomux_set_gpr_register(1, 19, 1, 1);

    else if (cpu_is_mx6dl())

        mxc_iomux_set_gpr_register(13, 0, 3, 4);

}

static struct fsl_mxc_tvin_platform_data adv7180_data = {

    .dvddio_reg    = NULL,

    .dvdd_reg    = NULL,

    .avdd_reg    = NULL,

    .pvdd_reg    = NULL,

    .pwdn        = adv7180_pwdn,

    .reset        = NULL,

};

Hi,

The adv7180 is supported already in the imx6qsabreauto. You could use the camer.apk to test it.

. The procedure of porting TVIN

(1)Adjust BSP files of your design.

As I previously mentioned in our Sabre-AI board, ADV7180 is supported, you could open "myandroid/kernel_imx/arch/arm/mach-mx6/board-mx6q_sabreauto.c" and refer to code for adv7180, then add them into your BSP file.

(2)Adjust HAL code of camera

Hardware Abstract Layer of camera is at path "myandroid/hardware/imx/libcamera/", After reading corresponding code , you will know how to modify them for you design.

I hope that helps,

Alejandro

Hi,

     The adv7180 have worked well, there is a hardware mistake cause LLC signal do not output to CSI pixel clock pin.

Thanks for your reply.
