Nespi case plus safe shutdown question/issue

almulder

how many wires are pluging into the raspberry pi it shoudl be a 6wire /10pin unit, also the usb from the case must be pluged into the usbport on the raspberry pi. What command did you run to install the SafeShutdown script? Did you manually install it or use the wget -O - "https://raw.githubusercontent.com/RetroFlag/retroflag-picase/master/install.sh" | sudo bash

@almulder I'm pretty sure there were 6 wires in the 10 pin block. I recall pin 2, 6, 9, 10 being blank off the top of my head. And yeah I installed the script via that command, then double checked al the actions of that shell file to make sure they had worked, which they seem to have done.

The USB is also plugged into the top left port which I saw some notes online saying was necessary for the older model (top left not plugging in)

almulder

Odd I got the Case+ and installed the script, turned the switch selector switch to on and it just started working. (USB port plug should not matter, as I have moved mine to different slots when pulling it out and putting it back during testing.)
Did you create the image of your SD card from scratch or used a premade one?

codecomp

I just went to the downloads page and clicked the big red 2/3 download button and burnt it into a new formatted SD card with Win32DiskImager. I didn't want to try starting with loading it on top of Raspbien with my first install.

It is sounding like a hardware issue more and more. The only working source I've found is a short video after someone stick their pi in the case and said "Look you can turn it on/off with this button" but skipped over the script install.

My debugging just threw me for a loop as I could not work out the logic of how that power button should work. Passing power through on activation but labelling power as a button and the actual power button as a LED. I thought one of the wired might be going to the wrong pin when I was able to get power off working by changing the LED pin to a button. But while the shutdown command worked, powering back on would not without unplugging and plugging back in the cable.

almulder

post your script you have installed from your pi. (SSH would be the easiest way to copy and paste)

almulder

also make sure that in /etc/rc.local that the SafeShutdown is listed. should look somehting like this

# By default this script does nothing.

# Print the IP address
_IP=$(hostname -I) || true
if [ "$_IP" ]; then
  printf "My IP address is %s\n" "$_IP"
fi

"/opt/retropie/supplementary/retropie-manager/rpmanager.sh" --start --user pi 2>&1 > /dev/shm/rpmanager.log &
sudo python3 /opt/RetroFlag/SafeShutdown.py &
dmesg --console-off
exit 0

@codecomp please check your rc.local first. Then is the LED blinking over boot process? It is just a bit flickering during the first few seconds then it glows solid.

@mitu look at the process how they call the commands. A sudo call in rc.local .... And later they make sudo shutdown calls. So 3 time superuser (it is like a cinema with all superhumans in one film... The Avengers: Mission RetroPie) ... So it can be true that the vendor did not create the script at his own ;)

codecomp

The rc.local contains the expected sudo python 3 call to the SafeShutdown.py script. Thought I'd mentioned that before but must have been part of my deleted ramblings, whoops. But I did verify the install process did do it's job best I could.

The LED however does not blink on boot, just goes strait to solid. Tested again with the board set to on and off in case of faulty wiring just to be sure.

I just got the new superpi snes case from retroflag and my safe shutdown doesn't work either.

Script used:
wget -O - "https://raw.githubusercontent.com/RetroFlag/retroflag-picase/master/install.sh" | sudo bash

Switch on pcb is set to on.

Pi 3B+
Running 4.4 updated all packages

Edit: I do have a fan in my case using 3.3v power using gpio pins.

Any idea on what to try to fix this?

almulder

Did you get it working? if not post the contents of this file. /etc/rc.local

HurricaneFan

@almulder Yeah, its working now. @cyperghost found a fix for the 3B+.
