Hi all,

I shared my test results and solutions in attachments.

Best regards,

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

init.rc

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

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

terrytan · ‎06-23-2013

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.
