Hello All,

 

I have a custom board with 800x480 resolution lvds connected. I see 4 tux logo coming up as soon as kernel boots. But the bootanimation is blank.

 

I see the bootanimation when it is connected to HDMI. What might be the issue?

 

below are the bootargs :

 

LVDS:

 

setenv bootargs 'console=ttymxc0,115200 init=/init video=mxcfb0:dev=ldb,LDB-WVGA,fbpix=RGB32, bpp=32 fbmem=28M fb0base=0x27b00000 vmalloc=400M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=448M buildvariant=user androidboot.storage_type=emmc androidboot.selinux=permissive androidboot.dm_verity=disable'

 

HDMI:

setenv bootargs 'console=ttymxc0,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 bpp=32 gpumem=512 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=448M buildvariant=user androidboot.storage_type=emmc androidboot.selinux=permissive androidboot.dm_verity=disable vmalloc=400M'
