@semper-5 said in METADATA not saving - Favorites will never remain tagged:

@cyperghost nope nothing. I deleted everything and followed instructions, redid it twice and just straight power off. no metadata save

But you did a reboot so the script became active? Or you can start the script by SSH with sudo /path/to script/switch.sh &

Semper 5

@cyperghost oh yes I have rebooted and powered on and off about several times.

it can't be a wiring problem because I put the original script from Yahmez back in and power off and restart functions work fine again

cyperghost

@semper-5 Then I'm sorry. As I don't understand how the POLOLU works I can't help ... but now you still miss the metadata.

/home/pi/RetroPie/scripts/switch.sh

oh when I run the command straight from SSH I get:

sudo: unable to execute /home/pi/RetroPie/scripts/switch.sh: No such file or directory

but I can SEE the file and when I edit it, all the content is there...am I going crazy?

cyperghost

@semper-5 Did you insert the text via nano command? and did you made it executable with chmod +x /home/pi/RetroPie/scripts/switch.sh

Semper 5

@cyperghost yes. but I'm looking at the same file with the same content in both nano and text editor on WinSCP

cyperghost

@semper-5 Close the WINSCP viewer, or close WINSCP at all... and just use the CLI provided by putty. WINSCP sometimes uses it's cache to display files. Then on reboots/restarts it messes the system up with old files.

I need the info if the script is working in the basic variant - just for tomorrow (going to bed).... because then I can provide a full working solution with better handling of the emulator calls ;)

Semper 5

@cyperghost yeah tell me about it I'm cursing at my computer right now and I'm still at work past 5pm lol!

so I am using ONLY CLI (using F4). no putty no winscp.
I can see the script. I can edit the info and see the content. but when I execute it using sudo /home/pi/RetroPie/scripts/switch.sh I get

No such file or directory

Wondering if I should bump up to the 4.4 :/

cyperghost

@semper-5 I think it doesn't matter if it's 4.4 or 4.3

With CLI I don't mean to enter terminal by quit ES. Without ES running in background the script will do nothing. So just use SSH and putty to edit the files. Maybe it is also a good idea to start the script through SSH (so you can read error messages)!

Can you check if I setted the right GPIOs? As I said in my example yesterday... Without the POLOLU I was able to trigger right as I used a wire and just connected GPIO24 directly to PIN1 (3,3V) ... Proper shutdown.

So I guess the detection routines of ES and EMULATORS still work. But I don't know the switch shematic of your build.

Stupid question: Did you create folder scripts within your home directory?

Semper 5

@cyperghost I tried moving and recreating the script in 5 various places but it keeps coming back as command not found
this is just getting crazy...i can see it sitting there smiling at me but saying "nope, not gonna do it"

PS: there's no stupid questions when dealing with a dummy lol

cyperghost

@semper-5 hmmm and if you try sudo bash switch.sh
I changed the script again to view status message!

julenvitoria

Hi guys! I'm trying to close ensurely saving metadata with an script... @cyperghost is your script doing this? Could the script be valid to power off with a generic button?

Thanks in advance

I'm getting something new. and this is on a totally fresh image with nothing but the button script and yours.

this is the output when running your script:
switch.sh: line 17: echo: write error: Device or resource busy
switch.sh: line 19: echo: write error: Device or resource busy

Well... "Button script"?
Then it's clear whats happening. The Button script and "my" script are using the same GPIOs. Please disable the Button script and try again ;) We are getting closer :)

@julenvitoria
Yes it works with a generic button. Therefore comment all lines that contain $gpiopin2 - these aren't needed. But it's not a well written one. I just want to find out if I'm on the right track with this to use the POLOLU device.

Semper 5

@cyperghost more developments, still just cuts the power. and this is the only script I'm running on a fresh image.

@semper-5 You copied the contents of the script in Notepad by any chance ? Use Notepad++ to create/edit the scripts in Windows and set the line endings to Unix (LF), Notepad saves with Win/DOS line endings (the extra \r character in the script file).

Semper 5

@mitu yup that's what I've been using the whole time (Notepad ++)
I've made scripts with no problems many times before. but its just getting hung up on this one

anyway I can get this script in RAW? I could clear up just a few of the errors but not the rest. :/

cyperghost

@semper-5 The best way would be to edit with SSH connection and nano.

use putty, don't use WINSCP

cd /home/pi/RetroPie/scripts
1.1 if directory scripts does not exists use mkdir /home/pi/RetroPie/scripts
1.2 then try again with cd /home/pi/RetroPie/scripts
rm switch.sh this will remove script
nano switch.sh copy text from code box below
3.1 After inserting code with left mouse button
3.2 Press CTRL+X and press Y to save script
chmod +x switch.sh makes script executable
sudo ./switch.sh & to start script in background with root privileges ;)

@semper-5 It's very strange... for example lines 10, 13, 16, 22 and 26 are blank... It works for me but not in the totality of the emulators.

@cyperghost As I mentioned it really works for me, but not in the totality of the emulators... For example it works with retroarch and advancemame but doesn't work with pifba, pcsx-rearmed or mame4all. If I try the commands separately pgrep -f doesn't detect this emulators... pgrep -f "$emucall" doesn't show any pid. Any suggestion for detect the emulators properly?

Thanks

cyperghost

@julenvitoria Thanks for the headup. As I wrote this is just a basic script! meleu is the RegEx wizard out here. I changed codebox.... please try again.
I added emupid="$(pgrep -f "$emucall" | tr '\n' ' ')" pkill -P "$(echo $emupid | tr ' ' ',')"
PS: That are the outfindings of @meleu

I'm working on annother emulator detection - Shutdown script some input for better emulator detection

The errors @Semper-5 descripes are caused because these "empty" lines contain Carriage Return (CR) character (0x0D, \r) ... Windows uses linefeed (LF) and carrige return (CR) for creating a new line.
