Orange Pi Zero 3

Interesting question. The dxf says the part in question is labeled ED1 besides CP18 and CP14. I found both CP18 and 14 in the schematics but ED1 not. Either mislabeled or I didn't catch it.

why edge kernels missing the dvb modules?

Probably because nobody had use for those until today. Feel free to send a PR adding whats missing.

Looks like both current and edge on sunxi64 are missing dvb support. Is this intentional? sunxi kernels include it, as do most other families.

What you’re seeing is open-source maintenance in practice. It’s not centrally orchestrated. We only manage to do this for some key features while DVB support is present in some kernels, but it’s not guaranteed to be consistently enabled across all targets unless someone explicitly maintains this functionality.

I have a Orange Pi Zero 3 4GB Board. It uses a Micron LPDDR4X RAM and H618 Processor. I have tried a plethora of distros and tried to change Uboot and DTB but unable to make it work. Spent days on Gemini and Claude but no luck. Below is the output from UART debuggger:
