Dear Carl,

Our application is same as yours, but a little different.

LCD 800 X 480

TVE  TV-NTSC

I followed the user guide to modify the init.rc and complie and replace the files: overlay.imx5x.so, gralloc.imx5x.so.

The result is LCD display not normal, TVE is green.

Uboot cmd:

console=ttymxc0,115200 init=/init quiet lpj=4997120 pmem=32M,64M fbmem=10M gpu_memory=96M vmalloc=512M video=mxcdi1fb:YUV444,TV-NTSC tve androidboot.console=ttymxc0 di0_primary video=mxcdi0fb:RGB24,CLAA-WVGA

hi Terry,

The patch only works for HDMI output.

Could you try the following modification with an extra property to rollback TV conf to original BSP?

---

diff --git a/libgralloc/framebuffer.cpp b/libgralloc/framebuffer.cpp

index e2f19e2..f9ab189 100755

-        property_get("rw.DUAL_VIDEO_SIN_UI", value, "0");

Dear Max,

Tested, but TVE output green, and it has picture sometime. But LCD doesn't have output.

Thanks,

Terry

hi Terry,

Can I know if the TVE feature is normal on your board based on original BSP?

Regards,

Max

Dear Max,

The original BSP can output normal TVE NTSC.

Best regards,

Terry

hi Terry,

ok. I have no board with TVOUT, but please let me prepare the environment for TVOUT & LCD. I will update later.

Max

Dear Alex,

I.MX53 QSB has both VGA and LCD output.

You can get the TVE from VGA port.

Best regards,

Terry

hi Terry,

We have a workaround to force dual video of MX53QSD work for legacy TVout.

You may reach Carl for the workaround.
