i'm so sorry this is the first time i ask question

my board is mx6q_sabresd

in uboo-imx board/freescale/mx6q_sabresd/mx6q_sabresd.c

i have some changed in code

i hope my uboot logo is ldb=dul1 1024x768 rgb=24bit but i get the logo on screen are four pictures, two is my uboot logo others are my kernel logo

my bootargs is

setenv screen2 'setenv video video=mxcfb0:dev=ldb,LDB-XGA,if=RGB24,bpp=24 video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32 video=mxcfb2:off fbmem=14M,28M vmalloc=512M ldb=dul1'

if(strcmp(s, "RGB555") == 0)

val = IPU_PIX_FMT_RGB555;

else if(strcmp(s, "RGB565") == 0)

val = IPU_PIX_FMT_RGB565;

else if(strcmp(s, "RGB666") == 0)

val = IPU_PIX_FMT_RGB666;

else if(strcmp(s, "BGR666") == 0)

val = IPU_PIX_FMT_BGR666;

else if(strcmp(s, "BGR24") == 0)

val = IPU_PIX_FMT_BGR24;

else if(strcmp(s, "RGB24") == 0)

val = IPU_PIX_FMT_RGB24;

val = IPU_PIX_FMT_BGR32;

else if(strcmp(s, "RGB32") == 0)

val = IPU_PIX_FMT_RGB32;

else if(strcmp(s, "YUYV") == 0)

val = IPU_PIX_FMT_YUYV;

else if(strcmp(s, "UYVY") == 0)

val = IPU_PIX_FMT_UYVY;

else if(strcmp(s, "YUV444") == 0)

val = IPU_PIX_FMT_YUV444;

else

val = IPU_PIX_FMT_RGB666;

printf("fixfmt = %s %d\n", s, val);

ret = ipuv3_fb_init(&lvds_xga, di, val,

DI_PCLK_LDB, 65000000);

if (ret)
