Hello,
I downloaded android_jb4.2.2_1.1.0 with all source code and
patches and I built an image for our Sabre SDB board.
I changed the kernel command line in this way :
BOARD_KERNEL_CMDLINE := console=ttymxc0,115200
androidboot.console=ttymxc0 vmalloc=400M init=/init
video=mxcfb0:dev=hdmi,1920x1080M@60 video=mxcfb1:off
video=mxcfb2:off androidboot.hardware=freescale fbmem=28M
to support HDMI video (not LVDS as default command line in the
same file).
When operating system starts, kernel boots and Android boots
but on the display the image is as picture atteched.
Why ?
Thanks,
Paolo Patierno
Hi,
I can not see the kind of Monitor you are using but it looks like the resolution is not suitable for it. However, pleae try this steps in another hdmi monitor to make sure it works.
In the U-Boot prompt, set the U-Boot environment variables as shown below:
U-Boot > setenv bootcmd booti mmc3
U-Boot > setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M
init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off
fbmem=28M androidboot.hardware=freescale
U-Boot > saveenv
Regards
