Safe Shutdown not working - NESPi 4 case

[lhari84]

Hi,

I did a fresh install of RB 8.0 on NESPi 4 case. RB is installed on SSD, if this matters.
Now I wanted to activate Safe Shutdown, as I always did on previous versions of Retroflag cases:
Just commented in following line in recalbox.conf:
system.power.switch=PIN356ONOFFRESET
Also the physical switch in the case is set to "ON", to enable Safe Shutdown.
It's not working at all, neither safe shutdown, nor safe restart (reset button).
I'm out of ideas, hope my new case isn't broken?

Thanks in advance for your help!

@lhari84 hello

https://forum.recalbox.com/topic/24395/recalbox-v7-2-1-nespi4case-installation-tutorial?_=1641069647508

On the 8.0 version, i can't install the case. I can change just the case=Nespi4case:1 line and it works but... the power button manage to activate the safeshutdown but doesn't stop the power. (the fan is still activated)

@scavy Hello

Ok thanks, so this is a known issue?
I have followed the RB changlogs for a long time and it showed up many entries suggesting the case works properly, too bad it does not, I really thought it would.

Now I have added the case=NESPi:1 line but same situation as you wrote: RB shuts down safely, but Pi will not power off.

What I do not understand so far, is this case working properly in any other constellation? For example if using microSD instead of SSD?

Completely different question:
Do you think the Pi4 will be ok without a fan, just a (small) heatsink? My case has been delivered without ANY cooling solution, so I put a heatsink on CPU and placed a fan in the case, that was delivered with an older Retroflag Pi3-case in the past. The fan fits well, but the noise drives me crazy...

@lhari84 I experienced the same error.

As far as I understand the script which is responsible for handling the buttons is not compatible with the python version in Recalbox 8.0. This is a known issue: https://gitlab.com/recalbox/recalbox/-/issues/2067

There are two merge requests that should solve it:

• https://gitlab.com/recalbox/recalbox/-/merge_requests/2072
• https://gitlab.com/recalbox/recalbox/-/merge_requests/2083

With version 7.2 it worked out of the box, with version 8.0 it only works if I apply the changes from the merge requests. I have tested it on an RPi3 in a NESPi+ case and on an RPi4 in a NESPi4 case.

I have a GeekPi heat sink in both cases mentioned above, and it does a good job: https://thepihut.com/products/raspberry-pi-4-extreme-cooling-heat-sink-fan-kit

It can be connected to either 3V or 5V. I choose 3V. This way it is really silent and still keeps the Pi cool enough (tested e.g. with playing Dreamcast games on the Pi4 in the NESPi 4 case).

@woife Sounds good, so I will wait for the fix to start over with the Pi4 Case then.
Further I will not upgrade my good old SuperPi Case with Pi 3B+ to 8.0 for now, as you have mentioned the older generation unfortunately is affected too.

Regarding the cooler, thanks for the info. I have thought about ordering this one, but was not sure it would fit and if it's more silent. Now I know

@scavy Hi,

Now, after updating to 8.0.1, I still can't get it working. Is there anything I should/can do?
Both methods case=Nespi4case:1 overwriting and system.power.switch=... (common activation paramater in recalbox.conf) will not work.
Same as with 8.0, system will shutdown, but NESPi 4 case will not power off.

Changelog does not specify which Retroflag cases have been fixed, maybe NESPi 4 is not yet?

@lhari84 Hi

Try this :
https://forum.recalbox.com/topic/23588/problème-configuration-safe-shutdown-avec-le-nespi-4-case

It worked fine for my Nespi4 case.

@micklabrique
Thank you so much, my missing piece was the following modification :

mount -o remount,rw /boot
echo "# Overlay setup for proper powercut, needed for Retroflag cases" >> /boot/config.txt
echo "dtoverlay=gpio-poweroff,gpiopin=4,active_low=1,input=1" >> /boot/config.txt
shutdown -r now

Hi.

I read those threads and I dont know what I have to do.
Could anyone explain it for somebody that has not high kwoledges.

The original script was installed by me just pasting a line gave in retroflag’s web in the consolé

Thanks in advance.

@jor2404 for the NesPi4Case :
1/ Connect the Pi4 to the case and activate the safeshutdown button. Use the case manual to install it correctly.
2/ Install recalbox 8.0.2 if not done lol
3/ Connect your Recalbox to the internet. Connect in SSH. Authorize partition boot writting with this command : mount -o remount,rw /boot.
In the boot part look for the recalbox-boot.conf file. Open it.
Look for the case=none:1 line. Change it by case=NESPi4:1.
Save the changes.
4/ Still in the boot part look for the recalbox-user-config.txt file. At the end of the file, add this line : dtoverlay=gpio-poweroff,gpiopin=4,active_low=1,input=1
Save the changes.
5/ Reboot, your NesPi4Case is totally operationnal
