GBA Zero involuntary shutdowns

[kevinhorsten]

Hi,

Hardware: Freeplay Zero with Pi 0 W.

Image: Tried the past 3 sd-image 2101/2201/2501 all give me the same results.

I have the following problem:

It boots up fine into ES, when I don't touch it nothing happens it stays booted, I can even navigate between Ports and Retropie with dpad, but as soon as I enter into retropie a second laten it starts shutdown down.

Anybody any ideas?

Hey Kevin,

My first thought was to make sure that your power button springs back (like a DS Lite). If it stays in the ON position (like a GBA), then you probably need to cut the nub off of the slider. Let me know if you think that may be an issue here.

The next thought would be that the Pi pin that is used for the power button is bridged/soldered to something else (or maybe not making a good connection).

I assume that you have batteries hooked up, but if you don't, I would recommend that you have a battery plugged in.

Also, see http://freeplaytech.com/troubleshooting if you haven't already.

done some testing, hocked up a keyboard and all is fine. from the testing I did it looks like it has to do something with the A-button. As soon as i hit the A button moments after the system is shutting down.

I think I've found it. Turns out joy-A and poweroff - on GPIO are next to each other, so I'm guessing these two must be connecting. I've had this build for months now and haven't had this issue before. Weird that these two gpio pins are now all of a sudden getting bridged.

Yeah, I agree that it's odd. Did you take it apart recently or something?

Also, if you have a way to SSH in (or use the keyboard), you could run

jstest /dev/input/js0
or
gpio readall

To see what the buttons are doing. With jstest the power button will act a little bit odd, but you might see if you tap power does it also show that A is being pressed.

Thanks, I'll definitely check these command.

Gonna try to desolder/solder these pins again to try to clean them up and hopefully that will do the trick.

Hi,

Been on vacation for a while but this problem has been solved. It turned out the A-button and the Power-Off pins were shorting.

Thanks all
