IPU congfig

Hello

I have for display in our own board,HDMI,LVDS,RGB24,MIPI.I want to config IPU as follow:

LVDS:

ipu_id = 0,

disp_id = 0,

HIDMI:

ipu_id = 0,

disp_id = 1,

RGB24:

ipu_id = 1,

disp_id = 0,

MIPI:

ipu_id = 1,

disp_id = 1,

Now,I am confused by LVDS config,the lvds can work well with the following config:

{

ipu_id = 0,

disp_id = 0,

ext_ref = 1,

mode = LDB_SEP0,

sec_ipu_id = 1,

sec_disp_id = 1,

}

Our hardware only connnect LVDS0,we do not need lvds seprate mode,so how to config ldb_data structure to config lvds only use IPU1_DI0?

Hi,

You can try to config "mode = LDB_SIN1" for one lvds only.

You can try the setting in u-boot command firstly.

add "ldb=sin1" paremeter in the command line.

Thanks very much!

Change to LDB_SIN1 does not work,and then I change to LDB_SIN0,it works,I think the reason is that my hardware connect to LVDS0 interface.

Now,my ldb_data structure is as following:

{

ipu_id = 0,

disp_id = 0,

mode = LDB_SEP0,

}
