Hi,

Have custom hardware is based on i.MX535 Sabre platform.

The primary display connected is TFT LCD, while the secondary display connected is Component TV-Out.

 

The custom BSP is based on the Android R10.4 release.

The following links were referred & applied the patches specified for "DUAL_VIDEO_SIN_UI"

The video is seen on the TV, but it is with a green background. Do we need to make any other configurations? Is there any settings to be done with respect to the color conversion mapping? Pls advice.

 

The following are the configurations done:

1.bootargs

setenv bootargs 'console=ttymxc0 init=/init root=/dev/mmcblk1p2 rootfstype=ext4 rootwait di0_primary pmem=32M,64M fbmem=10M gpu_memory=32M video=mxcdi0fb:YUV444,TV-PAL tve'

2.init.rc

   SECOND_DISPLAY_ENABLED 1

3.init.freescale.rc

   setprop rw.SIN_VIDEO_DUAL_UI 0

   setprop rw.DUAL_VIDEO_SIN_UI 1

   setprop rw.secfb.disable-overlay 1

4.ueventd.rc

/sys/devices/platform/mxc_sdc_fb.0/graphics/fb* fsl_disp_property 0660 system graphics

/sys/devices/platform/mxc_sdc_fb.1/graphics/fb* fsl_disp_property 0660 system graphics

/sys/devices/platform/mxc_sdc_fb.0/graphics/fb* mode 0660 system graphics
