[Pre-Order] Safe Shutdown Switch (PowerBoost Version) - Closed

[DarrylUK]

It didn't play the video :-/

Are you using my modified script?

I used the script on the front page from GitHub. It seems like the safe shutdown is working:

I've left it on now on the menu, I'll see what happens when it's low again.

Honestly I have no idea what's happening. I rebooted after posting the video and the shutdown script isn't working.

When I launch the monitor manually via the below:

Code: Select all

python ~/GBZ-Power-Monitor_PB/gbz_power_monitor.py

I'm not presented with anything at the prompt (is that correct?). If I power off whilst in this state there's a half second delay or so and then it just cuts power. If I stop the script via ctrl + c I get the attached message. Is that expected?

This is the code used to add it to the startup process:

Code: Select all

echo "@reboot     /usr/bin/nice -n 19 /usr/bin/python ~/GBZ-Power-Monitor_PB/gbz_power_monitor.py" >> mycron; crontab mycron;rm mycron

I just don't know at this point if it's the script that's not running or if it's not being added to the startup process correctly.

Clear your cron jobs with:

Code: Select all

crontab -r

Then add the job again. See if that helps.

I've removed and re-added it, it doesn't seem to be working at all. Is there a way to verify the script is running apart from physically turning the device off?

[Camble]

@DarrylUK Honestly, I'm not sure. I haven't done much software stuff with the Pi yet. The bulk of that work was by @Popcorn. I just tweaked the script for this board.

[DarrylUK]

I will try a clean install of retropie and the script tomorrow. I'll let you know how it goes.

Typing, ps aux | grep python, at the command prompt should give you all running Python scripts and their paths.

Yes

Yes

Thanks for that. I just ran it and it showed 2 instances of it running. I cleared my cron jobs, rebooted, verified no scripts were running, added it once, rebooted, checked again and it shows 2 scripts running.

Does that tie up with you @Camble?


Edit, I'm not sure if it makes a difference that it's being powered on in a low battery state. I'm charging it now to see.

[DarrylUK]

I have reflashed Retropie 4.0.2, installed the script, verified that it's running on startup and when I flick the switch, it turns straight off. I think I'm ready to call it a day with this.

Has it got anything to do with it being installed locally (e.g. permissions)? I download the GBZ-Power-Monitor_PB folder from github, copy it to the correct location on the SD card, the script is running on startup. All of the solder joints are good, it has even worked previously (the shutdown switch part). What could have happened for it to have stopped working?

Just set it back up and checked. Yes, it's listed twice.

Just noticed you mentioned the battery is low. Which GPIO pin are you using for the keep alive?
