I use the patch and compile the image with the armbian.
Compilation is ok.
There isn't tve overlay to use, i don't know if it's necessary.
I power on the board with the image builded and Image work and I can connect via SSH but no image output.
I also test to add tve overlay to image, add tve to dts overlay Make file. I now have the dtbo tve file but adding it to overlay don't give me the solution, no image output.
If I use old kernel (with fex) image output via CVBS works.
UPDATE: add the patch for enable tve overlays kernel-sunxi-current.patch
