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'
