yes, I have been following the guide entirely...just other have experienced, when I add that to the config file, I get the kernel panic message and when I remove it, it goes away.

strange ... I'm also getting a kernel panic ...

after adding following command line the Pi starts to shutdown:

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
After short booting I'm getting kernel panic ...

thats how my config.txt looks:

Code: Select all

max_usb_current=1
dtoverlay=gpio-poweroff,gpiopin=22,active_low="y"
dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4
disable_audio_dither=1

it's working now for me (without power plugged) ...

I have replaced the /boot/config.txt with this (I have done these before) and added the "dtoverlay=gpio-poweroff,gpiopin=22,active_low="y"" line ...

http://www.mediafire.com/file/5am8ss7b7 ... config.txt

edit: ok, it's strange ... after some successful shutdowns I'm now receiving the kernel panic after booting. Looks like the Pi immediately shutsdown after the script started. Checked the wiring -> ok; checked twice -> ok ... I have no idea

Some people have had issues with the cable plugged in. The board I'm using to test here works with or without the charging cable, so I'm having trouble replicating the problem again.

Your /boot/config.txt looks fine. The one you posted has the first 55 lines commented out, so not really much different to what you had.

@Spruc3Moose Have you tried a fresh image?

There is a way to force the Pi to reboot on kernel panic. With this board, it should power everything off at that point.

To /etc/sysctl.conf, add:

Code: Select all

kernel.panic = 1

@camble

I have tried many fresh images on two pi zeros and I have still not seen any safe shutdown video...power switch still just shuts down the pi immediately.

I added the kernel.panic = 1, but now the pi reboots when I initiate a shutdown from the emulation station menu.

It will kernel panic if the switch is set to ON and you shut it down manually, yes. Because the PowerBoost will not power off unless the switch is set to OFF.

So i'm not sure what the next step is to make the safe shutdown work...if I flip the switch off, it still just shuts down immediately

Does this happen when just running on battery?
