LVDS output problem

Hi

Now, My project uses two channel LVDS to output 1080P image, and use an FPGA to sample。

Now,my problem is that we can test waveform from CHx_DATA0,CHx_DATA1,CHx_DATA2, but can not get any wave form from CHx_DATA3?

The following is my LVDS config in bsp:

static struct ipuv3_fb_platform_data sabresd_fb_data[] = {

  {

  .disp_dev = "lvds-lcd",

  .interface_pix_fmt = IPU_PIX_FMT_RGB32,

  .mode_str = "LDB-XGA",

  .default_bpp = 32,

  .int_clk = false,

  .late_init = false,

  },

};

static struct fsl_mxc_ldb_platform_data ldb_data = {

  .ipu_id = 0,

  .disp_id = 1,

  .ext_ref = 1,

  .mode = LDB_SPL_DI1,

  .sec_ipu_id = 0,

  .sec_disp_id = 0,

};

Can anyone give me some idea?

Hi 千

I would suggest to look at link below with example which supports 1080p lvds lcd
