OS:Android4.4.3/kernel:V3.10.53/uboot:V2014.04 +imx6dl 板子

 

HDMI output only  ,uboot  有關 bootargs如下,此組參數就可以順利開機到桌面

bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32  video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off vmalloc=400M androidboot.console=ttymxc1 consoleblank=0 androidboot.selinux=disabled androidboot.hardware=freescale ldo_active=on cma=384M

 

LVDS or LVDS+HDMI output ,uboot  有關 bootargs參數

bootargs console=ttymxc1,115200 init=/init  video=mxcfb0:dev=ldb,bpp=32  video=mxcfb1:dev=hdmi,1920x1080M@60,bpp=32   video=mxcfb2:off video=mxcfb3:off vmalloc=400M androidboot.console=ttymxc1 consoleblank=0 androidboot.selinux=disabled androidboot.hardware=freescale ldo_active=on cma=384M

 

在bootargs參數中只要有dev=ldb,bpp=32,開機就會停在"Starting kernel ..."

只要把dev=ldb,bpp=32拿掉就可以順利開機

 

麻煩協助...謝謝
