A solid green means the pipeline has been correctly set up in regard to the clocking,
and some (invalid) pixels flows to the HDMI transceiver.

This means you can consider the HDMI & clock portion OK, and propably the ENCP aswell.

The OSD video pipeline is the following:

[ DDR -> VIU (RGB2YUV) -> VPP (Blending of planes, Scaling) -> ENCP (Pixel generation) -> HDMI-TX -> TMDS]

Green means value 0 in YUV, this means 0 is in the YUV pipeline, so it must be an issue with the VIU
part reading from DDR and doing the color conversion.

Check in the downstrean source code how the SC2 VPU is initialized, and looks at the differences since SM1.
Look at the VIU & VPP stuff init.
