Raspberry 4 retropie after shutdown I have to reflash
So basically I got this raspberry 4 for 25 dollars, I've never owned a raspberry before nor have I operated Linux. I got an SD card and a usb flash and got it to work. I choose a game, my start button to go back to emulation station doesn't work so I shut it down. When I power it back on it gets me to a screen like cmd on windows with the name "busy box" nowhere on the internet have I found a similiar problem. Every time I shut down I have to reflash because I can't get to emulation station a second time without doing so

Serial UART not working with non-booting Fedora39
# About my pi
- OS: Fedora Server 39
- Model: 4B
## The Problem
Fedora Server goes through U-Boot, then starting services and then the screen is black (No Signal). My Serial UART also refuses to connect after this time.
## What I've tried
- Re-formatting the SD Card using a variety of tools (arm-image-installer, RPI imager, dd, Rufus, balenaEtcher)
- Setting the "nomodeset" parameter
- Connecting the Serial UART, with and without the 3v3 and 5v connections.
### How I've tried to connect
- Screen and minicom on Arch Linux
- Putty on Windows
Please ping me in any response!

rpi4 model b 4gb on boot red and green light on solid with new flashed fresh sd card

no green light on pi 4
Hi there. I was running mainsail on my pi and until recently it was working fine. Now only the red light comes on and it doesn’t seem to boot. I confirmed my power source is 5.3v . I tried plugging it into an external monitor to see what it is doing and it said no signal. I checked the sad card. It seems fine, but I tried a second one just in case. I can’t see any physical damage to the card, and no reason why it would have suffered any. But I’m at a loss.

which architecture am i using? raspberry pi 4 b
Hello, i'm not understanding which architecture i'm using on my raspberry pi 4 b, 'sudo dpkg --print-architecture' throws 'armhf' but 'arch' throws 'aarch64' and neofetch throws 'OS: Raspbian GNU/Linux 11 (bullseye) aarch64' and in the past i have only been able to install armhf .debian files, so i think its using armhf, if it is using armhf, is it possible to start using aarch64 or both architectures on my current system? like upgrading or something?

Using Arduino GPIO directly from Raspberry PI (RPI.GPIO)
So I was searching for the fastest method to send a 5v signal from the raspberry pi to other components and I saw the serial communication on arduino, this have a lot of problems from me, I just want to directly send the 5v signal and I came across this image.
the website didn't have anymore in depth information, but comparing it to other information I got from chatgpt I think we could directly control the arduino pins by setting the pins ias output in the setpu, and having the same pins number as output in the raspberry. did anyone ever try it? as I think that I might have understood something wrong, I also don't trust chatgpt for codes except for him to find missed semi-colones or other typos

Missing component and short circuit(RPI02W)
Hello, i have RPI zero 2W and my hdmi fell out, i soldered it back and its not a real problem, a real problem is that i accidentally soldered two contacts(highlighted on image attached) alltogether, and when i connected it to power supply, my cable literally melt, i removed that component and lost it(yeah, im kinda stupid), and now its booting and working, but hdmi does not work anymore. Please, tell me what was that component i removed(i highlighted it with red thing on photo) and what it does on that SBC 👉👈

test if external usb is bootable
so I got a external USB drive with the intent to boot off of it for my rasberry pi 3 B HA install (HA = Home Assistant, an image the rasberry pi imager supports).
I set the usb boot flag using sd card on my pi3, but it wasn't booting off my external usb drive or giving any image on my monitor.
The pi3 boots the HA image from microSD no problem, and the external usb drive is recognized by windows 10 no problem (as a data drive anyways). The external USB drive only shows 1 partition in disk management, but who knows.
So I want to rule out that the external usb drive is the problem... by booting off it on a regular computer. Any suggestion on what/how I should image it?
I tried rufus imaging reactOS onto it but that failed to boot... before I give up on this drive any other suggestion for how to image it or tips to make it work?
I suspect it has something to do with its embedded USB to SATA controller.. which I know nothing about.
edit1: I was able to boot ubuntu iso off the external usb drive.
edit2: booting off the microsd card into pi, I was able to usb mount the external drive, so the drive is mountable in the pi
edit3: I double checked the boot flag, it's fine
edit4: I saw a video where they booted off a usb key, so I tried that. no go. I think I can eliminate the external drive and say my rasbery pi 3 B isn't botting off USB properly without a sdcard.

Buttons not working on GPIO Hat
Ok, I have solved every problem I have had and this is the last hurdle.
I have this HAT and following the documentation:
https://www.waveshare.com/wiki/1.44inch_LCD_HAT
Except in the demos in C and Python the button presses on the hat do not get detected.
I manually wrote a script in python to output ot the console when a button is pressed by following this guide (it uses RPIO):
https://raspberrypihq.com/use-a-push-button-with-raspberry-pi-gpio/
With the Waveshare Demo and that guide, it does still not detect any button presses. I am a bit lost on how to test it.

Pihole DHCP problems
I have pihole setup as the DHCP server for my network. I've got a mesh network which unreliably connects to pihole.
My problem is that sometimes I get disconnected from my mesh network and onto my ISP router which has poor coverage.
I think it's smth about the leases since when I remove my device info from the dhcp.leases file I can reconnect.
Any ideas on how make it work properly?

custom gui
I have an application I made using C++ and Python. My question is, can I remove the desktop environment and still run these programs via command line?
If I do that, will my programs still display a gui?
I have a 128x128 waveshare 1.44inch hat, can I get the program directly displaying on there?

screen hat
I am currently using a RPi Zero w2 with a waveshare 1.44 inch hat.
It displays the desktop perfectly. An issue I have is that FBCP only works in 32bit OS. Are there any alternatives that work with 64bit OS that achieve the same thing? I read FBCP does not support 64 bit.
Or maybe a different screen that supports 64 bit OS? Or maybe a solution (wrapper perhaps?).
Thanks

Raspberry pi official touchscreen issue
I’m using a raspberry pi model 3 and the official 7” touchscreen. After a crapton of messing with the config file I managed to run raspbian on the pi and get to the home screen. Unfortunately, only a small top left portion of the screen works. Of course I have tried calibrating but no luck because I can’t even reach other corners. Mouse and keyboard work fine. I have seen people have this problem before, but there seems to be no solution. Did anyone have a similar experience? They are powered using the official power adapter and I’m running Debian 10 because 11 wouldn’t work at all.

static public IP address
I need a static public IP address but have no clue where to begin. I need this for a wireguard vpn, it will be set up on a pi 4 along with wireguard and will be used not only to encrypt my data when I'm not at home but also allow me to access my pi and let my pi hole block ads for me even on the go. any help is appreciated so thank you for even reading this. once I have this set up I feel like life's sorted for me lol 😂

Unable to boot after cloning SD to SSD
I'm trying to move from an SD to an ssd using rpi-clone. I've gone through the install and am able to get it to do the clone using rpi-clone sda. It does it's transfers and looks like it's successful but it doesn't boot. After powering off and removing the SD card and powering back up It gives an error
Gave up waiting for root file system device. Common problems:
Boot args (cat /proc/cmdline)
Check rootdelay= (did the system wait long enough?)
Missing modules (cat /proc/modules; ls /dev)
ALERT! PARTUUID= d2a8e92e-02 does not exist. Dropping to shell!
I've tried two different usb drives. A Centon and a kingston a400. Both give the same error. I also now can't boot off the original SD card as it gives the same error as well.

pihole, bitwarden,nginx unbound in portainer
Hello, I'm trying to setup bitwarden and nginx in portainer, i was running PiHole without portainer but decide to remove it and use portainer, i tried changing the port to 8080 but it didn't seem to let me open the web interface, when i did that on normal install it worked. Having problems installing nginx because it's mixing ports. I'm also having troubles setting up unbound with my pihole through portainer, anyone have a guide for this?

Trouble setting up multiple SSIDs on raspberry pi 4b
Ok, so I am having trouble setting up a second SSID for my raspberry pi 4. The first ssid was setup using the raspberry pi imager so I am not sure if that is where the problem lies.
I can add things to wpa conf however when I try to save any config changes I recieve a "FAIL" message. I am not sure what's going on but having acces to that second SSID is crucial to the project that I am working on. Any help would be appreciated.
Thank you in advance.

Use GPIOs in multiple Threads
Hey,
I wrote a python program that opens multiple threads (less threads than the cor can max handle, so no overload) and I defined some gpios as inputs_pullups and as outputs. The threads should use the gpios and act with them, but I get no reaction. The code works, except for the GPIO interaction. does anyone know what the problem is, had similar problems or knows how to fix it?
here is an excerpt of how the gpios are used with the trads:
import RPi.GPIO as GPIO
import threading
def led_test():
while true:
PIO.output(led_one, GPIO.HIGH)
button_state = GPIO.input(bt_pin)
if button_state == GPIO.LOW:
PIO.output(led_one, GPIO.LOW)
led_thread = threading.Thread(target=led_test)
led_one = 24
led_two = 18
bt_pin = 27
GPIO.setmode(GPIO.BCM)
GPIO.setup(bt_pin, GPIO.IN, pull_up_down=GPIO.PUD_UP)
GPIO.setup(led_one, GPIO.OUT)
GPIO.setup(led_two, GPIO.OUT)
PIO.output(led_two, GPIO.HIGH)
led_thread.start()
