ED078KC2 powering issue

[GoReNeY]

Hi, thanks for this great project, a lot of work has been done!

I have a problem working with ED078KC2 and v7 board I bought from there

On booting the controller, there was no sign of anything happening, so after some debugging, I found out that when my screen is connected to the board, the power controller does not seem to output the needed voltages at all, and my FW dies on this piece of code:

So the loop checking if power is ok will not end. But when the screen is not connected, everything works fine. Screen was checked on another controller, so it's fine too, and I don't really know where to look for the issue.

I'd be glad if someone could give me a tip on where to go to fix this problem, thanks!

Hm, you have an oscilloscope to see how the power behaves? That screen should be working fine, maybe there is some component slightly faulty/ not contacting well so the power chip can't handle the full load... Maybe a multimeter would be enough to see which line is not coming up. Am 18. Oktober 2024 14:25:35 MESZ schrieb GoReNeY ***@***.***>:
