hi,All:

Excuse me !

Why imx6 android4.3 BSP Dual display setting will change color with the left and right split?

Examples:

setenv bootargs 'console=ttymxc0,115200 androidboot.console=ttymxc0 fb0base=0x27b00000 vmalloc=400M init=/init video=mxcfb0:dev=ldb,LDB-XGA,bpp=16 ldb=sep1 video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=16 video=mxcfb2:off fbmem=10M.28M androidboot.hardware=freescale'

video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=16  -->  Use bpp = 32 will generate to change the color and the left and right sides cut case.

Please help me, thanks.

Hi

seems i.MX6 IPU does not support bpp = 32  internally, please check

Figure 37-4. IPU internal pixel formats i.MX6DQ Reference Manual
