How to change SABRE-SD screen resolution in LOLLIPOP(5.0.0?

Hello,

 

I'm working on sabre sd board (imx6dl) and trying to switch to a different display. But the bad news, i'm new to Android.

The resolution of the LVDS display that comes with the board is 1024x768. However my new display is 1024x600 LVDS and it does not support EDID.

 

In the u-boot, it says; "No panel detected: default to Hannstar-XGA"

I have edited the resolution of this panel in "mx6sabresd.c" and that fixed the resolution of the u-boot (and the u-boot logo).

 

But the resolution inside Android (lollipop) is still wrong. The bottom of the screen is outside of my display.

I have tried editing "BoardConfig.mk" like that

"BOARD_KERNEL_CMDLINE := console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,1024x600M@60,if=RGB666 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=400M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M androidboot.serialno=1e1b29d4dbc91258"

and that

"BOARD_KERNEL_CMDLINE := console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,1024x600M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=400M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M androidboot.serialno=1e1b29d4dbc91258"

Nothing changed.

 

The display works fine, but the bottom area is still outside of the display.

 

Could you please tell me how to change the resolution?
