Hi All,

 

I am using IMX6 based custom board and running kitkat from freescale. The kernel version is 3.0.35.

 

The HDMI and LCD displays are working fine  but LVDS display is not working fine. Please let me know if any issues in the code changes.

 

Below i copied the fb structure for your reference. Also attached my board file for your reference

 

static struct ipuv3_fb_platform_data sabresd_fb_data[] = {

        { /*fb0*/

        .disp_dev = "hdmi",

        .interface_pix_fmt = IPU_PIX_FMT_RGB24,

        .mode_str = "1920x1080M@60",

        .default_bpp = 24,

        .int_clk = false,

        .late_init = false,

        }, {

        .disp_dev = "lcd",

        .interface_pix_fmt = IPU_PIX_FMT_RGB24,

        .mode_str = "CLAA-WVGA",

        .default_bpp = 24,

        .int_clk = false,

        .late_init = false,

        }, {

        .disp_dev = "ldb",

        .interface_pix_fmt = IPU_PIX_FMT_RGB666,

//        .mode_str = "LDB-XGA",

        .default_bpp = 24,

        .int_clk = false,

        .late_init = false,

        },

};

 

 

 

static struct fsl_mxc_ldb_platform_data ldb_data = {

        .ipu_id = 0,   // ASHOK

        .disp_id = 0,

        .ext_ref = 1,

        .mode = LDB_SEP1,

        .sec_ipu_id = 0,

        .sec_disp_id = 0,

};

 

Thanks,

P.Ashok

Hi,

I skimmed through the file and it seems to be fine.

I would start changing the IPU ids and see if there is any difference.

Hi,

Have you tried with a different IPU id? Do you want the LVDS1 to be your primary display?
