Green light issue.
Currently setting up my pi zero w.
Right after flashing raspberry pi OS however only the green light is on. Seems to be blinking every 800ms or so. Any ideas?
Looking into issue.txt it has 1 log from 2024-03-12 which is weird considering I didnāt have it then. Could this point to some pre installed software having issues? Any help is highly appreciated :D

any help is appreciated

2 raspberry pi 4s not booting anymore
Hi, I have 2 raspberry pi 4's and they are not booting anymore. 1 pi shows a solid green and red light and another only a solid red light. The power to the gpio pins work. I think that it has to due with a charger that I used with it. Is there anything I can do to troubleshoot?

Composite on Rpi4B with bookworm
Hi, I'm trying to enable an analog display, the things I've added to my config.txt are below
enable_tvout=1And
dtoverlay=vc4-kms-v3d,compositeAs well as
vc4.tv_norm=PALin cmdline.txt However when booting, the screen on the display shows the rainbow image, then flickers white, a second later the raspberry pi logo splash screen shows up for a split second and the screen goes black with nothing else. I read somewhere that the white flash is the pi deciding not to use that display, but what else do I have to change so it does? I've tried changing the config.txt to read
dtoverlay=vc4-kms-v3d,composite=1And
vc4.tv_norm=PAL video=Composite-1to cmdline.txt Like I saw someone do online but that hasn't worked either.

sending image from the raspberry pi to discord
Completely new to this. I got raspberry pi4 and I am trying to setup a security system that will send me pictures when the camera recognizes a face.
I just started working on this.
I heard we hooks on discord can be used to send a message from the pi to the app. How do I even begin with all this

Lighttpd Going back to port 80 when I have it set to 8081 on pihole
So I run Pihole on Synology NAS and everytime I update the container Lighttpd which is supposed to be on port 8081 is back on port 80 and then it fails because port 80 is used on my Synology NAS for web server which is on https://athernas.net and it gets annoying because It makes my internet experience slow and not work half the time if you need more let me know

My first ever Raspberry pi project [The PodBerry Touch]
So I like small sized phones that can literally fit in your palm like ipod or any old Samsung phone or the Palm Phone.
So I wanted to make a phone with a touch screen, headphone jack and a battery for charging and working without power cable.
I think a raspberry Pi Pico is good as it is small in size and cheap but I don't know about it's processing power

Iām trying to connect to mobaxterm Vnc with raspberry pi and it wonāt let me connect.
## Try this first i guess?
idk if this is right but it(mobaxterm) has smth to do with ssh right? maybe you've already connected to the ip address once on a diff device/flashed pi? in which case you can:
## delete the record from c:/users/username/.ssh/known_hosts
(just remove the ip address from the list- open with notepad or smth)

Help debugging TinyUSB crash when plugging in multiple devices?
I've hit a wall with a TinyUSB crash when plugging in multiple devices (https://github.com/hathach/tinyusb/issues/2556), and I was wondering if anyone would be interested in doing a live deep-dive debug session with me. We could do that here or the RP Pico Discord or perhaps SciCraft or EigenCraft. It's a fun way to meet new people and make new friends. š

Trying to connect by SSH to my rpi through cmd promp but the password doesn't input.
Essentially, I run "ssh bus@(ip adress)" then it asks for the password and it doesn't let me input anything. I can press anything on my keyboard it's like cmd prompt just crashes, but it still responds to "enter". I tried to change my keyboard to a bunch of other languages and it just doesn't listen. (yes, even the one that was listed in the imager)

How to change raspberry pi pico keyboard language
So i have 2 raspberry pi pico. My problem is that when i try to make it into a badusb it uses american keyboard layout. So when i want it to write example a "." it presses the . icon on a american keyboard wich isnt the same place for my swedish keyboard. I dont know how to fix this. I would assume the peope here outside of USA have exprianced this issue before since the language is American when it comes from the factory. Thank you for help!

ARM32 Bullseye Raspian Seeking for info on How to run script on boot/load. Tried for 3 weeks long
HellƓ, I'm tring to run this command on BOOT: this would be my optimal command [ sudo lxterminal -e "sudo ./Chataigne-linux-armhf-1.9.17.AppImage" ] since it loads a terminal with privileges and then opens the app with privileges as well. I've tried with rc.local, systemd and other common methods listed on the web (I think I can read and try all the lines written there but none seems to work), the closest I've suceeded is with bashrc so when i open a terminal, is automatically call the appImage. Thanks in advance for any help.

RPi5 Not booting or checking SD/USB drive
I have a brand new RPi5, I installed Raspian on a USB drive, booted up, connected via ssh, and ran apt upgrade. It crashed during the upgrade, and now does absolutly nothing when plugged in. All I get is a solid red light. I have tried different images on both USB and SD, pressing the button does nothing.
I assume the bootloader got messed up, since it doesn't even check the USB or SD card, and displays nothing on the hdmi out. How can I fix the bootloader if it doesn't access the attached drives?

else:

set_pin(1, -1)
set_pin(2, -1)
while True:
x = int(input("Pin (0 to 5):"))
light_led(x)
and i would like someone who understands better than me to help convert it to gpiod the gpiod documantation is a mess. Your help will be appreciated!

Pi CM4 with buggy integrated screen
Hi, i recently got a Raspberry Pi Compute Module 4 with an integrated 5" 720p touch screen (The reterminal from seeed, https://www.gotronic.fr/art-reterminal-5-cm4104032-34217.htm), and when it is powered, it does a weird visual bug, except for the little left area of the screen, which is not buggy, does this already happened to you ? Could it be the cables or something like that which are not properly connected ?
I correctly install the driver for the display, and when i connect it to an external monitor via the HDMI port, it doesn't do the bug, so it's well the integrated screen which has a problem

Mobile Display for 2 Websites
Hi all
I have searched quite a bit and think this should be feasible, but maybe somebody has good suggestions on the specific hardware I should get.
I would like to achieve the follwing:
a mobile, battery operated, rasberry zero powered device with a nice display, with a gsm card, that has a kiosk style OS that always shows the 2 same websites side by side, and the pages should autorefresh.
I'm thinking raspberry pi , original display with display case, gsm module, power bank, some kiosk style OS (or the standard OS?), i guess this should work out, right?
thanks a bunch!

meta-generating error
Hi, Sorry for the trouble, but I would highly appreciate if you could resolve this issue. So it all started when I just set up my raspi, and I also had a camera module, so I tried to test it using this repo: https://github.com/washieuanan/Raspberry-Pi-Emotion-Recognition. However, after the kind help of one of the mods, we seemed to be getting this issue: "metadata-generation-failed", we tried a reboot and everything but it still won't work. This was after using a venv because, when we ran the command pip install -r requirements.txt, we got the following error:. I would really appreciate help because this is urgent. Thanks!!

Speeding up refresh rate of raspberry pi 3'5 inch LCD display (GPIO controlled)
the FPS of my new touchscreen display is very low. Refreshes very slow at like 2 fps. I'm wondering if i can somehow speed this up. Even an increase of 3 fps could help. The drivers are pretty old I'm guessing - https://github.com/goodtft/LCD-show
Not sure what the brand or company is, I bought it straight from the Chinese manufacturer.

RPi 3B Slow & JavaScript heap issues
Hey guys,
I'm trying to serve an angular application using nginx on my RPi 3B (not 3B+, the title is incorrect), but I haven't even passed installing a simple angular application, as using npm install causes the entire thing to freeze (and i need to restart it by unplugging).
Every time i get issues such as:
FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory
or
INFO: task kworker/1:0:1273 blocked for more than 120 seconds (or 240 etc)
And the commands such as ng serve, ng build are incredibly slow.
Is there anything I can do? I am running the latest Ubuntu Server 64x LTS, installed node v20 and cloned a github repo, the rest is all still fresh.
