Multi Switch Shutdown Script!

Rion

@cyperghost Hi! Is your script compatible with mini-mods NesPi Fan Controller?

Efriim

I really appreciate this script and have used it since before I registered to the forums here.

Since I have had the same retropie build for a while and I uninstalled two or three other shutdown scripts before installing this one.

I like that I can exit the dreamcast emulator without having to use the controller. I was wondering about when I press the reset button to do this. I get this error:

rc.local[__]: /opt/RetroFlag/multi_switch.sh: line 63: kill: (___) - No such process

Is this normal behavior, and can I fix it?

I was also wondering about the fan_shutdown additional script.
When I turn my pi off, say using the Emulationstation menu to shutdown; the fan always stays on until I hit the switch on my case; Was the fan_shutdown script meant to turnoff the fan in that usage? If so what do I need to do to get it to work properly?
Thanks, @cyperghost

@Efriim This could happen if the kill command fails because the PID was closed already and the kill commands leads to a already closed process.
You can add a > /dev/null 2>&1 to python script in rc.local to get rid of it.

The fan script is needed for some old NESPi cases. Some users report the fan is still blowing without it. So your description sounds like that it can help in this case. I've a SNES case and I do not need it.

@cyperghost
I think I didn't describe the fan concisely. I was suggesting that the fan should be shutdown with the system e.g. sudo poweroff, and without having to get up and hit the powerswitch. What you say makes sense, that the fan wouldn't shutdown even when hitting the power switch on some cases.
I have Retroflag MegaPi Case.

@Efriim You may add the shutdown script according to the github description

Install fan_shutdown script: cd /lib/systemd/system-shutdown/ && sudo wget https://raw.githubusercontent.com/crcerror/ES-generic-shutdown/master/shutdown_fan && sudo chmod +x shutdown_fan
Install raspi-gpio with sudo apt install raspi-gpio
The shutdown_fan is setted to GPIO4 as standard
Therefore you might edit with sudo nano /lib/systemd/system-shutdown/shutdown_fan

The script will be executed miliseconds before shutdown and will cut off power and stops the fan from everlasting blowing.

I'm trying the different GPIO for the shutdown_fan as it isn't doing anything. I'll update if I am successful. The fan is not connected to the gpio however it is connected to the board that connects to the GPIO. I tried GPIO set 1,2,3,4,5,7,8,10 none did as I wanted it to do. Hitting the powerswitch turns off the fan as per normal.

@cyperghost Hi, along with the script and its shutdown function working for dreamcast. A new feature of the reicast emulator is to save the rtc setting to emu.cfg when invoking the exit by pressing the exit hotkey. Using the script reset button to exit the emulator does, so successfully however it doesn't save the rtc settings. Meaning I have the set time/date screen until I make a clean exit with the controller and this lasts for a month or so. Do you think we will be able to add this type of exit to the script for reicast?

I meant here that the reset button to exit reicast works and I am happy and proud to use this script. If there was a way to passthrough a command to reicast to initialize the poweroff where it saves the rtc, I would too like to know this.

Are you sure ? The RTC is saved in the NVRAM file (BIOS/dc/dc_nvmem.bin), not in the emu.cfg file.

Efriim

@mitu
The setting looks like this from emu.cfg
Dreamcast.RTC = 1543281985

The nvram needs to be within a number of seconds of this setting, that is why it asks for the time/date even if it has already been saved in the nvram.

@Efriim This could happen if the kill command fails. After 2 seconds annother kill command with -9 parameter is send to process and this will terminate the emulator. The only way I see is to use the NET commands retroarch offers. There you can send key commands to proper exit the core. Let me think about it ..,

Efriim

Though it is only with the standalone reicast, indeed. There must be a passthrough to the sdl to initialize the emulator to its shutdown state.

cyperghost

@Efriim oh yes and even it's not a libRetro core UDP will also fail. You may find a way to send signal level 15 to this core then it will save the day time

> /dev/null 2>&1

~~This broke some things, mostly only the rc.local stopped working. I shouldn't have added it to rc.local, but~~ It worked with rc.local as long as I'm not fumbling around on other things so much.

cyperghost

@Efriim Sorry ... I should think more about next time.
The output of stdout to /dev/null can't work. Because this output is needed for the python scripts to get response from the script. Maybe just send stderr to /dev/null is better? I did not test so far but I think that makes more sense. Yes, set it for the python script because this causes the error.

2>/dev/null

Yes /etc/rc.local is used for the retroflag script for automatic startup. But you can also use autostart.sh from emulationstation. That's the way I prefer...
You can edit with nano /opt/retropie/configs/all/autostart.sh

Broken means your installation does not boot anymore? Oh dear, you may edit the file from a second mashine?
About the commands... please don't forget to add an & at last sign. This will send the process to background otherwise the boot progress stops here.

Efriim

@cyperghost
Thanks. I got the rc.local to work again, I left one of these ">" when I deleted /dev/null.

When I made reicast from source with /dev/null added to the rc.local I didn't notice any build errors, though when I ran reicast.sh it did give me an error about /dev/null and wouldn't work. I recompiled it and it is not working still. So I guess I was dumb and it had not to do with that.

I don't know what is up with reicast, the controller used to work without ever setting it up, and then it stopped and the joyconfig didn't work and now the emulator wont even start.

Efriim

@cyperghost
Sorry for blaming you. It looked to me that way but I didn't think. They were concatenated in my head as I went from that to this and I apologize.

The reicast binary installation still works, maybe building has trouble with my environment or maybe it is just broke. The PS3 controller needed to be removed from the bluetooth and resynced because of the alternative driver, it is working again. And now I just might try to add the > /dev/null 2>&1 for the third time.

On top of that my powersupply was halfway falling out of the surge protector, and I couldn't figure out why I was getting low voltage errors, and I got experimental settings going on with 667 sdram_freq. And I couldn't even think of all the things that can't go wrong with /dev/null.

Yes the Reicast source is broken and the binary is somewhat broken, there is the older binary in the "working dreamcast games" thread somewhere and I'm using that now. The updated binary works for a while and then crashes on the second round. The errors are a gl get error 0x500 on start and about 15 OMX buffer underruns, which existed with the old version and persist if using "oss"

I thought about creating a new thread, it will probably get fixed eventually. Or is it more sensible to add to the github?

There is no need for an apologize, I never felt offended. But nice you sorted this out.

Maybe you can give feedback how we can get rid off some error messages.

Hi, hope I'm OK asking this here. My Google-fu has failed me, and searching has proved complicated.

I'm using the Mega-Pi case with your shutdown script and it works brilliantly. However I'd really like to hide the console text on shutdown for cosmetic reasons. I understand that sometimes things go wrong and output is needed when this happens, but I have a backup image and do not intend updating my system. I feel like I've finished my project now and would like to wrap it up with the addition.

I did find a comment somewhere that suggested to add >/dev/null 2>&1 to /etc/profile.d/10-retropie.sh. I did this and it removed the "terminated 671" line, but the console prompt remains. This is pretty much what displays before shutting down - alt text

I'd like it to simply go to a black screen if possible before shutting off. If you can help that would be very much appreciated. many thanks.!

@Ranma you need to edit the cmdline.txt file in the /boot directory.
I use this for all my pi projects and it hides all text during bootup and shutdown.

dwc_otg.lpm_enable=0 console=serial0,115200 console=tty3 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait usbhid.quirks=0x0079:0x1801:0x40 quiet loglevel=3 consoleblank=0 plymouth.enable=0 quiet logo.nologo

put it in all as one line.

Ranma

@lostless Hi thanks for replying. I've already got all that in my cmdline.txt file. I'd already followed a guide to silence the Pi during boot and shutdown, but it doesn't completely work. If I shutdown Retropie via the menu, it's completely quiet, but if I use the button on the Mega-Pi I get the console as above.
