Software Shutdown using Atxraspi

[crazydude2]

@cyperghost HI

I am using the python script and a momentary switch. What config do you want to know? I have tried them instructions but am still having issues. THanks for you help.

[crazydude2]

@mitu THanks. I have just realised i misunderstood what it means. I have run the command and now permissions are set to -rwxr-xr-x 1 root staff 611 Sep 18 21:44 softshutdown.sh

When i try to run without sudo it says there is a permission issue. Is this correct? It doesnt seem to run on shutdown

[cyperghost]

@crazydude2
Are you using an NPN transistor for software powerdown?

I have run the command and now permissions are set to -rwxr-xr-x 1 root staff 611 Sep 18 21:44 softshutdown.sh

That's correct as you are user pi?

Just for asking? Are you using the RetroPie Image proviede here?

[crazydude2]

@cyperghost Hi. Yes i am it is set up like this

I have just got the command to work over ssh using sudo softshutdown.sh. it does not work without that. permissions are set to -rwxr-xr-x 1 root staff 611 Sep 18 21:44

@cyperghost Hi

Yes i am user pi. Yes i am using the 4.2 image provided here.

[cyperghost]

@crazydude2 That's okay... you don't have root permission, so you are using sudo command ... why have you a group named stuff?

[cyperghost]

Can you edit python script with sudo nano /etc/shutdownirq.py?

[crazydude2]

@cyperghost Hi yes i can edit it. and i do not know why i have a group. I am not very experienced in this operating system so am trying to follow guides. Maybe one of them set it up

[cyperghost]

At first try the solution posted by @meleu --> Posted here

If this does not work take the lines above

---

Okay.... in your python script:
Edit the line os.system("sudo poweroff") to os.system("sudo /etc/es_shutdown.sh")

copy this to /etc/es_shutdown.sh
then sudo chmod +x /etc/es_shutdown.sh

#!/bin/bash

# End Emulationstation if condition of running binary is true (v1.59)
# v1.0 07/21/17 by cyperghost - Inital run 
# v1.1 07/22/17 - Added chown command to set right user permission for creating es-shutdown // cyperghost
# v1.2 07/23/17 - Some small improvments, easier to maintain, removed echo, removed else branch // cyperghost
# v1.5 07/27/17 - Great step to exit ES even if emulators is running by runcommand.sh are started // meleu
# v1.55 07/29/17 - all kudos go to @meleu for his alltime genious RegEx hack! // meleu
# v1.56 07/30/17 - All emulators will be detected. // meleu
# v1.58 08/02/17 - generel method: Use PPID to detect child PIDs now (ScummVM fix) // cyperghost
# v1.59 08/03/17 - nothing new, just polishing the code // meleu
# I just checked with SSH command - it saved my metadata! Maybe you need to extend sleeptimer!
# greetings @pjft for his famous favorits and @meleu for his RegEx sniplets and his constant help!
 
        emucall="$(sed -n 4p /dev/shm/runcommand.info | tr -d '\\"' | tr '^$[]*.()|+?{}' '.')"
        if [[ -n "$emucall" ]]; then
            emupid="$(pgrep -f "$emucall")" 
            pkill -P "$emupid"
            kill "$emupid"
            sleep 4
        fi    

        espid="$(pgrep -f "/opt/retropie/supplementary/.*/emulationstation([^.]|$)")"
        if [[ -n "$espid" ]]; then
            touch /tmp/es-shutdown && chown pi:pi /tmp/es-shutdown
            kill "$espid"
            exit
        fi
        # End Emulationstation if condition of running binary is true

poweroff

@cyperghost Hi. I have just given this a go. Now when i press the shutdown button the status flashes and nothing happens then after a bit of time it is like the power has been cut.

[cyperghost]

@crazydude2
What did you try?

1. This one
2. or this one

Is your metadata saved in your usecase? What do you mean with "status flashes"?

[crazydude2]

@cyperghost I tried the 1st one which did not work and then the 2nd one causes it to just cut the power. The atxraspi has a status led which flashes when in shutdown. At a guess it times out and just cuts the power if its not received the success signal. Perhaps that shutdown script takes too long? Nothing seems to happen in retropi before the power just cuts. The rest signal still works so i assume its still going through the python script

[cyperghost]

@crazydude2 So you press the button 4 seconds right?
And then a shutdown is performed, right?

Can you restart ES and type in SSH sudo /etc/es_shutdown.sh?
ES should shutoff and metadata is saved.

[crazydude2]

@cyperghost When i run from ssh i get this error message and then it shuts down
pi@retropie:~ $ sudo /etc/es_shutdown.sh
sed: can't read /dev/shm/runcommand.info: No such file or directory

It seems to shutdown correct if no metadata has changed from the switch. For example freshly turned on and then off. If i load a game exit back to check it is in last played when i use the power switch it just cuts the power rather than shutdown

[cyperghost]

@crazydude2 I have to take a look ... as I have not the atx here it's hard to suggest.

If you can switch to the install bash script it would be much easier

sudo wget https://raw.githubusercontent.com/LowPowerLab/ATX-Raspi/master/shutdownchecksetup.sh
sudo bash shutdownchecksetup.sh
sudo rm shutdownchecksetup.sh
sudo reboot

I guess the bash shutdown script can be changed to this ...

with sudo nano /etc/shutdowncheck.sh

[crazydude2]

@cyperghost Thanks for the help. This seems to work. I just need to remember to hold the button long enough as restart just shutdowns and leaves the atxraspi on which isn't ideal. Tomorrow i need to look into the software shutdown but i am not as worried about this as i probably wont use very often

[cyperghost]

@crazydude2
I made a small rework to the script to make reboot and shutdown for this script available here

For software shutdown with the transistor you have to edit
sudo nano /opt/retropie/supplementary/emulationstation/emulationstation.sh
delete all content and add new one posted down in this posting.

be aware... if you update RetroPie you may loose this script! as it is part of the RetroPie package!

Can you post your outfindings please?

#!/bin/sh

esdir="$(dirname $0)"
while true; do
    rm -f /tmp/es-restart /tmp/es-sysrestart /tmp/es-shutdown
    "$esdir/emulationstation" "$@"
    ret=$?
    [ -f /tmp/es-restart ] && continue
    if [ -f /tmp/es-sysrestart ]; then
        rm -f /tmp/es-sysrestart
        sudo /usr/bin/local/softshutdown.sh 1
        sudo reboot
        break
    fi
    if [ -f /tmp/es-shutdown ]; then
        rm -f /tmp/es-shutdown
        sudo /usr/bin/local/softshutdown.sh 4
        sudo poweroff
        break
    fi
    break
done

[crazydude2]

@cyperghost Hi I think it is now working well. Thanks for all your help. What do you mean by posting outfindings? Just so people know
nano /opt/retropie/supplementary/emulationstation/emulationstation.sh had to be changed to sudo nano /opt/retropie/supplementary/emulationstation/emulationstation.sh to allow editing

and the script also had to be altered to

#!/bin/sh

esdir="$(dirname $0)"
while true; do
    rm -f /tmp/es-restart /tmp/es-sysrestart /tmp/es-shutdown
    "$esdir/emulationstation" "$@"
    ret=$?
    [ -f /tmp/es-restart ] && continue
    if [ -f /tmp/es-sysrestart ]; then
        rm -f /tmp/es-sysrestart
        sudo /usr/local/bin/softshutdown.sh 1
        sudo reboot
        break
    fi
    if [ -f /tmp/es-shutdown ]; then
        rm -f /tmp/es-shutdown
        sudo /usr/local/bin/softshutdown.sh 4
        sudo poweroff
        break
    fi
    break
done

[cyperghost]

@crazydude2 Outfindings? ... tell me if it works ;)

make 3 backticks liker here ```
in beginning and ending of codeblock
One backtick ` in beginning and ending of line or word makes it red
__ makes bold
~~ makes striceout
_ makes italic

I'm wondering that you need root-access for editing this file!

can you post me output of ls -l /opt/retropie/supplementary/emulationstation please

[crazydude2]
