About the RetroFlag cases! Surprise surprise.... They can cut off power!

OhOhOne

@cyperghost
I double checked everything and its still not working.
I installed the original script by retroflag. It was working fine, but I wanted something that would save metadata, so I followed your directions posted in the other thread for replacing the original script with your own python scripts. But ever since then the power button just blinks red when I push it to off, and the reset switch doesn't do anything at all. I double checked and multi_switch.sh is there in /opt/RetroFlag and is executable, and I deleted the original python script and replaced it with yours (again, just to be sure). But its still not working.

Am I missing something? Did I skip a step?

EDIT: this is what I get when I type sudo nano rc.local:
GNU nano 2.2.6 File: rc.local

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

/etc/switch.sh &
/etc/switch.sh &
sudo python3 /opt/RetroFlag/SafeShutdown.py &
exit 0

cyperghost

@ohohone Why double /etc/switch.sh? Try to remove this first.
You can also remove the sudo from the python3 call. etc.local is already root

OhOhOne

@cyperghost
Okay, I made those changes to rc.local but there's no change, it still doesn't work. :(

cyperghost

@ohohone Sorry. I made just a quick try with the python code and it worked fine in my case. Maybe you can add a "print output" line to see if there is any value returned. But you can still use the bash script itself.Use the newest version. You can add it to rc.local or to autostart.sh with path/to/script/multi_switch --nespi+ &

Install raspi-gpio with sudo apt install raspi-gpio before. That should do the job.

Hi,
I think I got it all right, the reset button work just as it should and reset to the ES loading screen, but the power button doesn't work at all and the red led is still on when I press it.
Well i'm a begginer so there is probably something I'm doing wrong.

I also notice that with the safeshutdown from Retroflag ( wget -O - "https://raw.githubusercontent.com/RetroFlag/retroflag-picase/master/install.sh" | sudo bash ), if I want to turn off the pi, i have to switch the power button to off and then press reset. Switching th power button to off doesn't do anything on his own.

So yep, i'm lost ... :/

Please install the "shutdown_fan" script... type:
cd /lib/systemd/system-shutdown/ && sudo wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/shutdown_fan && sudo chmod +x shutdown_fan

This will cut power if you press power button.

The method the retroflag script provides works in most cases but it's a simple "killall" and it will fail if there is a emulator running in background.
But I'm a bit confused.... Reset works... Power on/off not? Did you set the NESPi-case switch to "ON"?

Please remove the retroflag script by editing sudo nano /etc/rc.local and remove the python entry.

@cyperghost im really confused. Retroflag says that their script does safe shutdown and safe reset. And to me it appears to be doing just that. How is this better?

cyperghost

@edmaul69 They do a safe shutdown by killing every instance of emulationstation binary but this method may fail if there is a emulator running in background. These may be a edge example but it's an improper way to terminate emulation station and is not clean way to save metadata.

Furthermore.... the reset button. It's just a waste of option with the original script as it just acts as a system reboot. The multi_switch script just resets the emulator (if there is one is running) and you turn back to ES main menu, or you restart just ES without performing a reboot (usefull if you changed metadata and want to save it, too).

All in all it doesn't matter which way you choose. Imho I would NOT use the original script but would stick to python and modify the original script like I've done here: Get text output from bash into you python script

In the end you decide ... I created the script to cover a lot of usecases and to make work to install switch to a Pie a bit more easier. Furthermore I learned a lot about handling command line parameters (used a uncommon method without shifting every single parameter).

In short why I don't rely on the retroflag script:

Fixed shutdown timer (5 seconds in every case)
The metadata may break in edge cases
Reset button is useless (imho)
(not related to the script itself) They change /boot/command to set UART for LED output
The python libary (GPIOzero) is a real heavyweight (but very comfortable I must agree)
I wanted to do something in bash ... as long as @meleu don't fixed the ES shutdown service (therefore I installed the --es-systemd parameter)

So I hope you are not confused anymore ;)

@cyperghost

Ok, I've instaled the shutdown_fan script, but it appears as shutdown_fan.sh1 , so I guess it was already there.

Sorry for the confusion about the Power switch , I'll try to be clear :
(The Nespi case switch is turned to ON)

-With the retroflag script, the Power on/off only works to turn on the pi. When I press the Power button to "off", it doesn't do anything. If I want to trun off the pi, i also have to press the reset button, see the retroflag script rolling to the end until it finally turn off the pi.

-With your script, it is the story, the Power off doesn't do anything but as the reset button only restart ES, I can't turn off the pi.

So yes, the Reset button work perfectly, the Power button works only in one way, when I have to turn On the pi.

PS: Today I have tested with a fresh sd card without the retroflag script, but this ended with the same result unfortunatly

PSS: Also I should mention my what I am working with :
-Nespi Case+
-Raspberry Pi 3 B+
-Kitty for SHH
-San Disk Ultra 16GB

@pwn3d_
Then I guess there is something wrong with the case.

-With the retroflag script, the Power on/off only works to turn on the pi. When I press the Power button to "off", it doesn't do anything. If I want to trun off the pi, i also have to press the reset button, see the retroflag script rolling to the end until it finally turn off the pi.

That's very curious. Usually the power button initiates a full power cut off if the GPIO is detected.

-With your script, it is the story, the Power off doesn't do anything but as the reset button only restart ES, I can't turn off the pi.

The reset and and power button are initiated all the same way. As reset works as it should and power does not work. I think I now I understand what may happening. It seems GPIO3 is not proper connected to your PIN header. You may check if it is attached right to the GPIO header. You can also reattach it to a new GPIO if you use ./multi_switch.sh --nespi+ powerbtn=xy & argument.
XY is the GPIO header.....

Because no script works in your setup, the error lies in your case.

PWN3D_

@cyperghost I will check all the wires and connectors right now

Also, if the switch in the nespi case is set to "off" the power button work just fine when I turn off the pi, but as you know it just kill the power.

PWN3D_

@pwn3d_ Oh, I'm getting somewhere : I tried to reattach the wire connected to the GPIO3 , to the GPIO11.

Then I typed : ./multi_switch.sh --nespi+ pwerbtn=11 &
the answer was : -bash: ./multi_switch.sh: No such file or directory

Ps: I have also checked in the /home/pi/RetroPie/scripts directory. I can see the multi_switch script as : *multi_switch.sh
I don't know if the * means anything

@pwn3d_ said in About the NESPi+ case! Surprise surprise.... It can cut off power!:

I don't know if the * means anything

It means is an executable file/script. Try typing the full pathname

/home/pi/RetroPie/script/multi_switch.sh --nespi+ pwerbtn=11 &

PWN3D_

@mitu Nope, I'm getting the same message :

-bash /home/pi/RetroPie/script/multi_switch.sh: No such file or dirctory

PS: Scripts ... with an s at the end ... yep that was it

cyperghost

@pwn3d_ said in About the NESPi+ case! Surprise surprise.... It can cut off power!:

yep that was it

= it does work now?

Annother question - just curious about the not working GPIO3.... Do you have activated I2C connection somewhere? Maybe that's the reason the GPIO wasn't initiated right.

The case uses the whole standard connection boards (I2C and UART) so I decided to develop command line parameters.

PWN3D_

@cyperghost No ...

But something else did the trick : I just went to edit multi_switch.sh

After "SWITCHTYPES" and "NESPIPLUS" , to #Set GPIOs, I just change GPIO_powerswitch=3 to GPIO_powerswitch=17 (my yellow wire is connected to this GPIO)

After a reboot, I tried the powerbutton, the red light blinked 4 times, I saw a script rolled, then the pi shut down completely !

So to identify the problem, does that mean the GPIO 3 on my raspberry is dead ?

I don't think it's dead... I think some I2C device is using this. So it can't be initiated. Interesting indeed!

about the command line parameter... you know ... powerbtn=11 is not GPIO17. You should write powerbtn=17 that would do the trick without changing the script. But glad it worked and now enjoy ;)

Yes, I noticed that, I confused with the number of the pin :)

I2C device? What is this ?

And Thank you so much for your help ! I learned a lot ! ;)

cyperghost

@pwn3d_

Yes, I noticed that, I confused with the number of the pin :)

https://pinout.xyz/# and now click on BCM17 (=GPIO17)
you will see ...

Physical pin 11 = Board numbering
BCM pin 17 = GPIO
Wiring Pi pin 0 = arduino like numbering ;)

In 95% of case we talk about BCM PIN

I2C device? What is this ?

It's a communication protocoll to attach sensors, simple displays, board expanders..... very helpfull for much much purposes. But maybe you activated it. Maybe with sudo nano /etc/modules you see some I2C entries.
