Shutdown and restart

pelliott321

I have RPi3 with latest version of RUNE
I just recently put this together and have been using with great fun and pleasure
But I have left RPi on and have had a power failure. The only way to get back running is to burn a new chip an reconfigure.
I have tried shut down but do not know to restart. I tried removing power and replacing and the system did not boot up. so I have to burn another chip and reconfigure.
So I am asking what is the proper shutdown and start up procedure

Hi pelliott321,

welcome to RuneAudio.

But I have left RPi on and have had a power failure. The only way to get back running is to burn a new chip an reconfigure.

This is a common issue with devices like the Raspberry Pi.

I have tried shut down but do not know to restart. I tried removing power and replacing and the system did not boot up.

This is the correct way.
- shut down your Pi via user interface (MENU->Turn off
- wait until the green light stops flashing
- now you can remove power
To restart the system you only have to plug in power.

The next image (version) will be available as a read only version.
This will prevent sd card corruption on power failure.

Or you can use something like this, but you have to modify RuneAudio to get it working.

wow thanks

What is the status of the build that will give a read only version of Rune? Any realease date?

Thanks so much for a great product!

I sent you this question in a separate message, Frank, but what modifications need to be made to RuneAudio to get the Audiophonics (France) Power Module to work correctly with the Shut Down menu ???

I tried using a standard image of RuneAudio on my Audiophonics RaspTouch. When I chose Shut Down on the menu, I got a Reboot instead of a Shut Down.

The Audiophonics image works properly, but not the standard image. What needs to be done ???

You need to install the code that handles the shutdown via the Audiophonics switch. See their tutorial: http://forum.audiophonics.fr/viewtopic.php?f=4&t=1620&sid=619fd50c689d22e5f93b906a16961c81 (in French..)

Thank you for the link to the Audiophonics forum. I did not know that it was there. I am really only trying to make a back-up copy of the MicroSD card that I bought from Audiophonics. I am happy with the way my RaspTouch is working, I just want a back-up MicroSD card in case of emergency.

My French is not too good. I also don't want to try to be a code monkey.

If I can't figure this out, I would like to buy another copy of the MicroSD card for my version of the RaspTouch. I cannot find this listed on their web site. If you know where this can be ordered, please let me know.

My next thought is to copy my existing card using HDD Raw Copy Tool. I hope that this program will copy from the front of the card to the back without fretting over slight differences in the byte capacity of the two cards. I will try tomorrow and post my results.

Hi K5DBB,

have you tried this image?
Should be the same as the one shipped with your Rasptouch.

No, but I would love to!

However, I cannot understand your link: mega:///#!8dplBCxD!2xdMBRvzqzj_hWMKEMPzh8ZUJsbtZT73EdXeDdFK-DE

Is there a standard URL that you could post for this ???

I searched the Audiophonics web site for a replacement RaspTouch card, but could not find one for sale.

Hi,

now the link should work.

Hi guys,
So in Raspian i managed to add a switch to a GPIO port and a python script to shutdown or restart the Pi. I found a script that worked and then modified it to suit my needs.

sudo apt-get install python-dev  
sudo nano /home/pi/offswitch.py

Then paste in the following text:

from time import sleep
import os
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(25,GPIO.IN,pull_up_down=GPIO.PUD_UP)
btn_timer=0
while True:
    if ( GPIO.input(25) == False ) :
        btn_timer = btn_timer+1
    else:
        if ( btn_timer > 5 ) :
            os.system('sudo shutdown -h now &')
        elif (btn_timer > 2) :
            os.system('sudo reboot &')
        elif (btn_timer > 0.5) :
            os.system('sudo ifup wlan0 &')
        btn_timer = 0
    sleep(0.5);

CtrlX to save and exit

sudo chmod -x offswitch.py
sudo python /home/pi/offswitch.py

The possibilities could be extended based on the duration of button press to activate other commands like restarting the wireless controller as per my last command. Now in the Runeaudio build I am struggling to know how I could implement the same procedure. Could someone please advise if the python install and script above would still work, the locations to install, etc?

Hi Raoul,

on my latest images python is installed by default.
If this is not the case for the image you are using, you have to install it with pacman.
Pacman is the packet manager for ArchLinux.

pacman -S python2

Thanks Frank. Do I save my files in the same locations as above?. I'm using the 0.4 version from janui and the command is not recognised so I assume it is not installed. I did find a python3.4 folder but the command did not run.within the folder either.

janui

Frank & Raoul,
I have tested python2 with the zero build. It works fine, install with:

pacman -S python2

RuneAudio 0.3:
python 2.7 - symlink: python2

fix 'python: command not found'

ln -s /usr/bin/python2.7 /usr/bin/python

RuneAudio 0.4b:
python 2.7 - symlink: python2
python 3.6 - symlink: python, python3

I do not appear to be able to get my original code to run with Python2.

from time import sleep
import os
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(25,GPIO.IN,pull_up_down=GPIO.PUD_UP)
btn_timer=0
while True:
    if ( GPIO.input(25) == False ) :
        btn_timer = btn_timer+1
    else:
        if ( btn_timer > 5 ) :
            os.system('sudo shutdown -h now &')
        elif (btn_timer > 2) :
            os.system('sudo reboot &')
        elif (btn_timer > 0.5) :
            os.system('sudo ifup wlan0 &')
        btn_timer = 0
    sleep(0.5);

This file is called offswitch.py and saved in the root folder. When I run

python2 /root/offswitch.py

i get the following message when i press my button on the pi:
sh: sudo: command not found

Does this mean that the code is recognising the button press, but not the code above? What do I need to change for Python2?

Hi Tall Person,

i get the following message when i press my button on the pi:
sh: sudo: command not found

On Rune there is no "sudo" installed and also not needed.
Remove "sudo" from your code:

os.system('sudo shutdown -h now &')

os.system('shutdown -h now &')

Frank, thanks. I can't believe I missed the sudo command was still in the code from my earlier working version with raspian debian....!
I'll have a look later and see if that solves the problem.
