I'm using dtoverlay = gpio-shutdown to send a shutdown signal, and when i short GPIO3 to ground I get a shutdown dialog on my screen. Is there a way to make it initiate the shutdown instead of popping up the menu?

64 Emulator on raspberry pi 5
So I'm new to both Linux and raspberry pi. I got this whole project I'm trying to do but to start off I'm trying to get an n64 emulator without using retropie as i still want to be able to access other programs.
i was able to install retroarch but cant figure out how to install the cores. I'm running into some issues trying to get mupen64plus installed, it just doesn't seem to install for whatever reason.
i tried following the guide on the github
git clone https://github.com/ricrpi/mupen64plus cd mupen64plus ./build.sh sudo ./install.shand even this one that i found
cd ~ sudo apt install libboost-dev sudo apt install libboost-filesystem-dev wget https://github.com/mupen64plus/mupen64plus-core/releases/download/2.5.9/mupen64plus-bundle-src-2.5.9.tar.gz tar -zxf mupen64plus-bundle-src-2.5.9.tar.gz cd mupen64plus-bundle-src-2.5.9/ sudo CFLAGS='-mfpu=neon -mtune=cortex-a72 -march=armv8-a' ./m64p_build.sh NEON=1 USE_GLES=1 VFP_HARD=1 NEW_DYNAREC=1but it kept saying no directory found when i did
cd mupen64plus-bundle-src-2.5.9/does anyone have a step by step "explain it to me like I'm 5" guide to getting one installed? or a simple way to install mupen that someone who has never used Linux can do? or am i just doing something incorrectly?

issues running pihole, openmediavault, Plex and nextcloud on Pi 5
Hello everyone,
I am trying to set up my Pi 5 to run:
1. pihole as dns server on my local network that works for all devices
2. omv as a nas that can be used by the other users AND by nextcloud as well as Plex
3. nextcloud to be reached from outside the local network too
4. plex that runs data stored on the nas
I am having troubles with making things work all together at the same time. I was able to successfully install each of them and run it, but I would lose connection to the nas. Any suggestions and maybe tutorials links are much appreciated.
Thanks in advance:)

SDK path issues
Hello
I recently started working with Pico's and decided to tackle learning C.
I bought a pi5 and installed everything.
However my install location is not the same as in the tutorial.
I have adjusted it in the bashrc file as in the uploaded img and rebooted.
However when I press build through vscode it gives an error and links to the wrong path.(Second pic)
Did I forget something?
Kind regards

Unable to boot
Hi All. I have been trying for a week to get my Raspberry Pi 5 to boot. I have tried two SD-Cards and a USB thumb drive to no avail.
If I use the custom config option in Raspberry Pi Imager, I get a screen that says its generating SSH keys and then it says rebooting, but it never comes back. If I pull the power and plug it in, I get the standard linux boot text scrolling for a few pages and then the screen goes blank, it never seems to connect to wifi using the custom config, and the keyboard has no power. The led stays red forever more.
I have tried all of the options in config.txt for hdmi, plus the video= option in cmdline.txt and nothing changes.
I have tried Raspberry Pi OS 64bit, Ubuntu, and Kali and all do the same thing.
The last item I have seen come up a few times before it goes to black is "BCM: Using default device address". Although it does seem to go black at different points, so I'm not sure if thats useful.
I am honestly at my wits end trying to get this working. Any assistance would be really grateful

Pi5: Unable to boot from NVME (Waveshare Hat+)
Hey! I've been trying to boot from my NVME drive for almost a week now with no success. I have a Pi5 with a Waveshare NVME hat, but when I try booting from it I get this error message:
Timeout: 00000000 3c301010 00000000 00000000
nvme: error 8
Failed to open device: 'nvme'
My BOOT_ORDER is 0xf641 (also tried with 0xf46 and 0xf64)
I can boot from SD and USB without issues, but if I boot from USB and set the root partition to the SSD my wlan0 disappears.
The drive I'm using is a Foresee E2M2 064G that came with my Steam Deck.
Any ideas?

Need help with enabling camera on V2 on Raspberry Pi 4 Model B
I'm completely new to anything raspberry pi related and I started a school project with it.
Here's a list of all the parts I've got from amazon:
Raspberry Pi 4: https://www.amazon.com/Raspberry-Model-2019-Quad-Bluetooth/dp/B07TD42S27/ref=as_li_ss_tl?dchild=1&sr=8-4&linkId=b48356bc3c6888cd7c44fd1130081d1a&language=en_US
Raspberry Pi Camera Module V2-8: https://www.amazon.com/dp/B01ER2SKFS?psc=1&ref=ppx_yo2ov_dt_b_product_details
Touch Display: https://www.amazon.com/dp/B09XKC53NH?psc=1&ref=ppx_yo2ov_dt_b_product_details
and ofc everything else like SD cards, display cables, etc.
I tried following this tutorial I found on Youtube: https://smartbuilds.io/smart-cctv-camera-flask-video-streaming-opencv-raspberry-pi/
One of the first steps is to 'Select Interface Options, Camera Port and select Enabled. You can now exit. This may cause your Pi to reboot." but no camera port option is showing up in the raspberry pi config. Any ideas? I've looked at countless articles and videos, but nothing seems to work.

Nema 17 Stepper stops moving randomly
Hi guys,
Im working on a little project where I need a Nema 17 Stepper. I paired it with a l298n module and control it with the Raspberry Pi 4B.
My problem is, that the motor works fine the first few rotations but then stops randomly. After stopping it just rattles and vibrates.
I already tried changing the connections and increased my power supply.
I tried using code from different tutorials online but nothing helped.
This is my code for testing the stepper:
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BOARD)
GPIO.setwarnings(False)
ControlPin = [7, 11, 13, 15]
for pin in ControlPin:
GPIO.setup(pin, GPIO.OUT)
GPIO.output(pin, 0)
StepCount = 8
# this two-dimensional array holds the eight-step sequence for half stepping
Seq = [ [1, 0, 0, 0],
[1, 1, 0, 0],
[0, 1, 0, 0],
[0, 1, 1, 0],
[0, 0, 1, 0],
[0, 0, 1, 1],
[0, 0, 0, 1],
[1, 0, 0, 1] ]
# GPIO.output(enable_pin, 1)
def setStep(w1, w2, w3, w4):
GPIO.output(ControlPin[0], w1)
GPIO.output(ControlPin[1], w2)
GPIO.output(ControlPin[2], w3)
GPIO.output(ControlPin[3], w4)
def forward(delay, steps):
for i in range(steps):
for j in range(StepCount):
setStep(Seq[j][0], Seq[j][1], Seq[j][2], Seq[j][3])
time.sleep(delay)
def backwards(delay, steps):
for i in range(steps):
for j in reversed(range(StepCount)):
setStep(Seq[j][0], Seq[j][1], Seq[j][2], Seq[j][3])
time.sleep(delay)
if __name__ == '__main__':
while True:
delay = input("Delay (ms)?")
steps = input("How many steps forwards? ")
forward(int(delay) / 1000.0, int(steps))
steps = input("How many steps backwards? ")
backwards(int(delay) / 1000.0, int(steps))
# this cleanup command is needed so that all the pins are reset once the program ends
GPIO.cleanup()

How to consistently connect my RPI 5 to may laptop?
I own a RPI 5 and I just started using it. I used the RPI Imager to install the RPI5 software and had it connected to my home WIFI. I initially used an ethernet cable to connect it via SSH with PuTTY and allowed the use of VNC. I used VNC and all that and connected to the Pi via WIFI. I got to control it and do everything with it. But after not using it for a while, whenever I open my Pi, it doesn't seem to connect to the internet automatically. I do not own a separate monitor to see what's happening within the Pi. I also am not able to connect to the Pi again via ethernet. I try using PuTTY again but it just says that the network is unavailable. The only way I get to connect to the Pi again is if I do the whole process again of installing the RPI5 software with the Imager program. If anyone can help me with this please it would be greatly appreciated. Thank you!

Script to reboot program on pi os if it failed to launch
Hello everyone im making myself a personal signage display that uses chromium that sometimes throws up this error. I have everything automated using .bashrc (pi boots up, unclutter loads to hide the mouse) then the command chromium-browser “website.com” -kiosk -incognito. It works 7 out of 10 times. The other 3 times I get thrown the error pictured below.
I was wondering if it was possible for me to make a fail safe that will detect that chrome didn’t successfully launch and commit a safe reboot to make a new attempt… thanks!
