LVDS output problem

thouswave — Tue, 31 Mar 2015 06:10:55 GMT

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

Best regards
