Hello everyone,
So I received the PHY chips, and I can confirm....that it came from there.
So in conclusion, if you have the DDR blinks which are faintly lit and the ETH socket blinks off and in your logs via TTL cable you have code similar to mine up to "eth%d: No PHY found".
there's a good chance that the PHY part is responsible for the control board not booting. Because it's one of the last parts to boot (after the CPU in any case).
The following diagram gave me a clue, as it clearly shows that the PHY module controls the ETHERNET, the LEDS and the magnetic.
I hope this has helped some people! (but I curse AMLOGIC anyway, it's poorly documented and fragile as hell).
I'm glad that you fixed the issue the only clue that I could see from your previous logs is the ethernet or a chip that is responsible for Ethernet.
Why not also post the source where you buy PHY chips? Can you share the code name of the chip you can read it under the chip as I couldn't find it on Zeusbtc if I type PHy.
