Powers on, powers off, then nothing [SOLVED]
« on: June 12, 2014, 10:45:23 AM »
I have connected my power source to the atxraspi and connected everything from the atxraspi to my pi.  When I connect the power wires up the pi powers on.

During the boot sequence I see the lines about the shutdown check, and everything works as expected.  When I hold the power button to turn it off, it works.

The problem is, after using the power button on the atxraspi to power down, I then cannot turn it back on with the power button and have to disconnect and reconnect the power wires.  As far as I can tell all of the connections are correct, is there anything else that could be causing this?

When you first connect the power wires from ATXRaspi to your Pi, does it power up automatically or does it require a button press?
It should only power up upon button press.
Do you have other devices connected to your Pi that draw power from the Pi and consequently from ATXRaspi?

Yep, it power on automatically when I connect the power.

I am using this in a PiBox (replacing the internals of an xbox with a pi).  The power cable is for a usb hub, which powers the pi and also connects via usb for connecting the front ports of the xbox case.  Currently, the only connectors attached to the pi are:
  • ethernet
  • hdmi
  • power (from hub via atxraspi)
  • gpio connectors to atxraspi
  • usb hub (data cable)

Something's not right, can you try the following:
Disconnect everything and leave only ATXRaspi and the Pi.
Recheck all the wiring between ATXRaspi and Pi.  You should have a MOMENTARY button connected on the BTN port (ON only when you keep it pressed) and a LED (without resistor) on the LED port - these are 4 pin holes on the North side of ATXRaspi PCB.
Make sure you got the TO/FROM wires connected the right way to your Pi.
The power to your Pi can be supplied throught the GPIO header 5V+GND or through the microUSB if you have a USB connector on ATXRaspi and a micro USB cable.
Once all these wires are connected plug in the power source directly from a power supply (not from hub) to ATXRaspi. It should stay OFF until you press the button.
Then it should boot and stay ON, until you press the button (hold it for ~3 sec) when it should start a shutdown sequence.
Once it's OFF it should turn back ON upon another button press and so on.

After checking what you asked it still didn't work, however I have now found the problem :)

It's with the pcb from the xbox's front panel, basically the buttons are designed to earth a single wire connected to them.  I thought when I cut all the traces and soldered my own wires straight onto the switch it would work but there must be some traces inside the board where I can't get at them, because removing the led wires fixes the problem (all the ground connections were connected to the same pin, therefore the led ground wire was connected to the switch).

Thanks for your time :)
