Raspberry Pi 4 won't shut down - trying /dev/input/eventX

[sylasebas]

Hello guys

I was wondering if you might be able to help me. I'm using a Raspberry Pi 4 together with a RetroFlag Nespi 4 case. In order to use the power button the case, I changed the recalbox.conf according to this post and remove the ; from line 14

# System Variable
# You can configure your recalbox from here
# To set a variable, remove the first ; on the line
 
# ------------ A - System Options ----------- #
#    Uncomment the system.power.switch you use

it seems to work as it starts to shut down, the LED is blinking but it doesn't power off.
The same happened before using the power button by just shutting Recalbox down via UI.

in the console, it shows the following message over and over again:

Trying /dev/input/event0
Trying /dev/input/event1
Trying /dev/input/event2
Trying /dev/input/event3
Trying /dev/input/event4
Trying /dev/input/event5
Trying /dev/input/event6
Trying /dev/input/event7
Not found.
Retrying in 30s.

does anyone have any idea on how to solve this issue?

Thanks so much and best regards, Sylas

thank you so much, that did it

I searched specifically the error message, didn't think too much about the case

I have a similar problem, but I do not have the NesPi4 case. I have a Pi 400, which is a stand-alone keyboard/case model that I have not modified from the manufacturer.

My setup is:

• Recalbox 7.3-Beta10
• Raspberry Pi 400
• Xbox One Series X Controller (QAU-00021) connected via USB

When pressing F4 to close Emulation Station and then ALT-F2 to access the terminal, the following is shown ad infinitum:

Trying /dev/input/event0
Trying /dev/input/event1
Trying /dev/input/event2
Trying /dev/input/event3
Not found.
Retrying in 30s.

No prompt comes up to enter a username or password, so I assume that it is impossible to access the terminal locally?

Fortunately, I do have networking enabled and SSH turned on. I logged in remotely via SSH.

After rebooting via SSH, I was able to access the terminal locally again. Any ideas of what might be causing this?

Recalbox 7.3-Beta10
Any ideas of what might be causing this?

BETA is only for BETA testers, because they know what they're testing and they know that BETA versions have a lot of bugs because it's a test version.

Use the latest official version if you want support.

@zing I did also experience this same problem twice when I was on 7.2.2 Reloaded. Same hardware setup.

It seems like the problem is intermittent for me. I don't know how to reproduce it. I could go back to 7.2.2 and wait for it to happen, but I would need to have some bread crumbs for what to investigate.

I do not have the NesPi4 case.

So your problem has no direct relation to this one, you should open a new thread.

It seems like the problem is intermittent for me

I don't believe it's a Recalbox bug, it seems to be a problem exclusively for you, as I don't see reports from other users.

but I would need to have some bread crumbs for what to investigate.

Use the latest official version, and the default theme and then check if it happens again, if it happens, open a new thread with as much information as possible.
Also test with another joystick if possible, intermittent errors can be caused by some bad hardware contact for example (I'm not saying this is the case, but it's a possibility).
