Superpi case - shutdown script not working.

campbell87

@mitu i removed the # and tested. Still it hung on the reboot: shutdown

i tried a re-install of the script and getting the same issue. Reset seems to work with no issues. Its just the shutdown thats not working.

Ive tried on 2 pi3b+ devices, and both having the same issue. Do you think it could be hardware related at all?

If it's hardware, then it might be the case. Can't be sure. The line you un-commented should signal the case that it has completed shutdown/poweroff.

What happens if you manually power off the Pi ?

campbell87

@mitu do you mean to trigger a shutdown without the case connected?

cyperghost

@campbell87 From what I see is that you used the uninstall script. Because the dtoverlay=gpio-poweroff is commented.

You said you installed the orginal from RetroFlag at first, because then there shouldbe a line like dtoverlay=RetroFlag_pw_io.dtbo instead.

Can you check /etc/init.d/rc.local please?
Maybe there are 2 scripts launched at the same time. To edit this file you need sudo rights so sudo nano /etc/init.d/rc.local does the trick. Thx

@mitu do you mean to trigger a shutdown without the case connected?

He means a shutdown by software, via ES menu for example.
It should do following. The Pie will not shutdown completly, you still have to press the button for complete shutdown.

Yes infact, this is needed for RPi4 for RPi3 the old script should still work. So a further test could be, to use the script I've posted and commentd the dto-line out from /boot/config.txt if then the Pie still hangs it's to 100% an hardware issue. Maybe connection is broken or something alike. GPIO4 needs a low signal --> PowerCut

@cyperghost still no luck :(. I have sent a mail to the supplier along with some images of the case, so il see what they come back with.

Thanks guys for the support :)

cyperghost

@campbell87 Hmmmm. Last chance, try to install the original script from retroflag. Then shutdown with software command, after that push the button, the light have to go off! If not your case is faulty then!

campbell87

@cyperghost so I've done a fresh install of retropie. You want me to try and install the original script from retroflag and perform a shutdown from emulation station?

When I set up the pi case, I have the safe shutdown switch to on, and leave the power switch in the on position, then I plug in the power.

I will give it one last go and report back.

cyperghost

@campbell87 Yes, you power on with the switch, then perform a shutdown via EmulationStation, the Pi should still show a red light. The you press the Power Button and the LED light should go off. If not then it's the case.

campbell87

@cyperghost so i did a shutdown via emulation station, and the picase light went off, but the pi stayed on. I then used the power switch to turn if off, but instead it boots it back up.

cyperghost

@campbell87 This is impossible! I have the impression that your case is faulty. There is never a powercut done in this constellation!

Everything worked as suggested:

Picase light goes off
Pie stays on (red light) Important and correct behaviour
You press the powerswitch and it boots???? That's wrong - it should go off then

This is telling me that GPIO4 was never set to off and the whole thing still keeps powered on.

campbell87

@cyperghost Yea, so i connected the power when the picase swtich was on, and the safe shutdown switch was on. I then shut down emulation station. The case light went off, and there was a steady red light on the pi.

I then turned the power switch on the picase to off, and it booted up and loaded into emulation station.

2nd thing i tried was leave the picase on and safe shutdown switch on, and then connect the power. Once i was in emulation station, i turned off the power switch on the case, the light on the case was flashing, script ran, and case went off for a few seconds, then booted back up again.

Tried same on both my pi devices.

cyperghost

@campbell87 Okay then please do following
edit sudo nano /opt/RetroFlag/SafeShutdown.py

Then on Line 31 is os.system("sudo shutdown -r now")
Just write os.system("sudo poweroff") instead

Reboot and let ES boot up, press then the power button - if then there is still a light on the Pi then you can easily get a new housing, it's defnitly wrecked then.

campbell87

@cyperghost made the change, but still same behaviour :(.

cyperghost

@campbell87 Okay then it's a faulty unit. Get an exchange

campbell87

@cyperghost I'm expecting a new case, tomorrow. Can I ask how I should install the script.

Do I connect it all up, leave the safe shutdown switch in 'on' position and the power switch in the on position, then turn power on at the socket?

Or do I install the script on the pi, then connect the case?

Thanks

Dan

cyperghost

@campbell87 It does not matter. Usually you set the Pi in the case, set the SafeShutdown switch to ON and start the Raspberry with Retropie.

You establish a internet connection and then type in the command by terminal or SSH. Reboot and it should work then.

campbell87

@cyperghost thanks. I will report back tomorrow.

campbell87

@cyperghost got the new case, ran the shutdown script and it works as expected!

the only difference on this case, is that the pi is powered by the case, so my power cable goes direct into the case, and not the pi.

thanks for the support!

Sorry did not get this.... The old case was not directly wired, so there was no plug to put on the GPIO header of the Pie?
Can you send a picture of the old case please?

Your description of the new housing is the usual wiring. But nice you get it working now :-D
Which script did you use now? If you use the crcerror script then you can terminate any running emulator by pressing reset button.
