[philipfeng]

Hi everybody,

  I got a problem with I.MX6 connect to LG's LCD screen LC420EUN by LVDS .

  This is a LCD with resolution 1920x1080 .

  I changed the uboot param to LDB-1080P60 mode , and the lcd not work correctly.

  After read some document , I know I should change the configure of the fb_videomode struct in ldb.c .

  But the LCD TIMING TABLE describe as below , and I don't know how to config the fb_videomode param , did any body know ?

Hi Philip

For 3.10.31 kernel, the attached patch was needed, the video mode is as followed.

For 3.10.17 kernel and older versions, just add the followed video mode:

video=mxcfb0:dev=ldb,LDB-1080P60,if=RGB24,bpp=32 ldb=spl1

Best regards

igor
