Might be a faulty FE1.1s, you could also try reflowing the pins on the chip and post pictures of this usb wire and be sure the length is not excessively long as that can cause problems,

Don't contact me about obtaining my board files (as you will not get them). Don't contact me about any of my boards if they are sold out, they will be restocked as soon as I can get them.


Don't support thieves like ckliang who copied my AIO to resell and is now cloning the mintyPi, support the original creators and not the thieves!

Hey Helder,
thank you! Resoldering the pins might have fixed the problem. Plugged the board to to my PC and it did not disconnect until now.

Cheers!

Hello everyone, I have some problems with my gameboy.
Last weekend I've finally assembled all parts and soldered pi to cartridge reader and aio board. First problem I faced was USB - retropie couldn't start when something (a simple keyboard in my case) is connected. Okay, I resoldered all USB wires and the problem is gone (in general).
But for now I can see the whole spectre of problems, from time to time:
1. Can't press A/B/X/Y buttons to configure them as gamepad buttons - but they work perfectly when I pressed any of them to detect AIO board for retropie.
2. Sometimes all buttons can be configured in the right way, but when I open retropie menu and press down button once or twice to go to raspi-config or even configuration editor section - Emulationstation reboots.
3. Again, when two other problems don't appear and I'm able to open setting page (to enter wifi pass, for example), the selector at the bottom row (where OK, Back, Finish are located) is jumping between all buttons and cannot be controlled with d-pad or keyboard.
What did I do wrong? Is it a general problem with retropie (i'm using 4.3) or with my wiring?

Yeah, it looks like your USB wiring is a tad too long and the Dat + and Dat - cables are not twisted.

I already twisted the wires while was lurking the forum for solutions :) And other problems are still here.
Anyway, is the length of usb wires really can be the reason of everything I described? Can't believe.

Finally I've fixed almost all issues, and it looks like they were produced by two reasons - inaccurate soldering of sd-card wires, and broken pads of safe shutdown board. I resoldered everything, and it works like a charm :)
Now my question (the most popular question in this topic, no doubts) is sound static. I checked almost all posts and solutions about it here, and my favourite one is shielded cables for pwm. Already tried it, and it doesn't really work for me, unfortunately. So my questions - can I use ground pads of R1\R2 buttons for shielding, or I should use one from powerstrip area? And is my twisted-shielding good enough, or ground wire must be longer?
Wiring (yes, I see that one of pwn cables is disconnected, it was fixed :))

Closing this thread because it's ridiculously long and Helder has his own support section now. :)

Please first search here for an answer to your question/issue, and create a new thread if you can't find anything.
