Question, i.MX6Q LinuxBSP LVDS setting

Aemj — Fri, 14 Feb 2014 06:05:30 GMT

Hi All,

I would like to ask about LVDS display setting on LinuxBSP.

My customer is developing his i.MX6Q board with 640x480 LCD connected via LVDS.

Please find the attached file for the timing specification of the LCD.

He is developing his software based on your LinuxBSP.

He tried some LCD settings written in ldb.c as follows but could not make the LCD work.

Could you give your advice on what setting he should use for the LCD?

For struct fb_videomode;

{ NULL, 60, 640, 480, 39722, 48, 16, 33, 10, 96, 2, 0, FB_VMODE_NONINTERLACED, 0, },// cea_mode

{ NULL, 60, 640, 480, 39682, 48, 16, 33, 10, 96, 2, 0, FB_VMODE_NONINTERLACED, FB_MODE_IS_VESA }, // DVI setting

{ NULL, 72, 640, 480, 31746, 128, 24, 29, 9, 40, 2, 0, FB_VMODE_NONINTERLACED, FB_MODE_IS_VESA },

{ NULL, 75, 640, 480, 31746, 120, 16, 16, 01, 64, 3, 0, FB_VMODE_NONINTERLACED, FB_MODE_IS_VESA },

{ NULL, 85, 640, 480, 27777, 80, 56, 25, 01, 56, 3, 0, FB_VMODE_NONINTERLACED, FB_MODE_IS_VESA },

BR,

Miyamoto

Dear All,

Sorry for my poor explanation.

The parameter entities listed in the previous post were added into 'static struct fb_videomode ldb_modedb[]' table in ldb.c.

Could you show me which of the parameters may suite for the LCD?

Please let me know if you need more information.

Hi,

Attached provides detail about display configurations on i.mx35. This method also apply to i.mx6.

Good luck! :smileyhappy:
