IMX6 quad plus display problem with HDMI

[pung2516]

Hi.

I am using IMX6 QuadPlus using Android SDcard booting with HDMI

i did all the settings such as 

""

U-Boot >   setenv fastboot_dev mmc1

   setenv bootcmd boota mmc1

   setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 consoleblank=0 vmalloc=128M init=/init    video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off    androidboot.hardware=freescale cma=448M galcore.contiguousSize-33554432 androidboot.selinux=permissive

   saveenv

""

After those settings are done and boot again,

i cannot see the GUI from the monitor using HDMI. All i can see is just a black screen. 

I got the error msgs like below kinda related to surfaceflinger.rc

[ 28.589633] init: Failed to bind socket 'pdx/system/vr/display/client': No such file or directory
[ 28.590065] init: Failed to bind socket 'pdx/system/vr/display/manager': No such file or directory
[ 28.590554] init: Failed to bind socket 'pdx/system/vr/display/vsync': No such file or directory

have no idea what to do..

Need your help. Thanks

From your above message it seems that your board can not read the screen. Which HDMI screen are you using?

About the HDMI display you can refer to our Android_Quick_Start_Guide document section:

3.4.2 Booting with single display: HDMI display
In the U-Boot prompt, set the U-Boot environment variables as shown below:
U-Boot > setenv bootcmd boota mmc2
U-Boot > setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 consoleblank=0
vmalloc=128M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off
video=mxcfb2:off video=mxcfb3:off androidboot.hardware=freescale cma=448M
galcore.contiguousSize=33554432 loop.max_part=7
U-Boot > saveenv
With the settings above, the Android platform does not start the shell console. To disable selinux, append
"androidboot.selinux=permissive" to the U-Boot's bootargs. Boot environment variables are as follows:
U-Boot > setenv append_bootargs androidboot.selinux=permissive
U-Boot > saveenv
