Parallel LCD issue on Android

[benoysaha]

Hello,

I am using a 24 bit parallel LCD(800x480) with sabresd board. I am using the android code provided by freescale. Here is the kernel commandline argument provided to activate the parallel display -

I am using the driver drivers/video/mxc/mxc_lcdif.c for the LCD display and confirmed that the following parameters in driver is confirming the display specifications -

static struct fb_videomode lcdif_modedb[] = {

{

/* 800x480 @ 57 Hz , pixel clk @ 27MHz */

"CLAA-WVGA", 57, 480,800, 37037, 40, 60, 10, 10, 20, 10,

FB_SYNC_CLK_LAT_FALL,

FB_VMODE_NONINTERLACED,

0,}

The problem is that the display is comming but it is bit distorted.

The following U-boot variable is used with the LCD :

video=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB24

As an example :

setenv bootargs_mmc 'setenv bootargs ${bootargs} root=/dev/mmcblk1p1 rootwait rw video=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB24 ip=none'
