Thanks!
I've V40 board, which is same as R40. I'm able to detect the HDMI but seems edid not detecting properly.

This seems like DT issue. Can you post somewhere your V40 DTSI (if it is different to R40) and board DTS?
same dtsi shared between r40 and v40, here is board dts support for HDMI[1]
This patch looks like exactly the same as mine for BananaPi M2U, so there should be no issues.
As I know, M2B is designed to be compatible with M2U, so most things should be the same. The stock firmware even use the same images for both M2U and M2B.
What about VCC-HDMI? Is powered? Can you measure it to check?
Best regards, Jernej
