Pi Pico in CLion Struggles
Hello fellow tinkerers!
I've been trying to set up CLion to work with building ELF2 an UF2 files, but I've been having a bit of struggles.
I'm trying to use the [Raspberry Pi Pico SDK]( https://github.com/raspberrypi/pico-sdk/tree/master ).
My host machine is Windows 10 and I'm using the [GNU Arm Embedded Toolchain]( https://developer.arm.com/downloads/-/gnu-rm ) as shown in the image.
cmake
cmake_minimum_required(VERSION 3.26)
# Check if SDK exists, it not then fetch it from remote git
set(PICO_SDK_FETCH_FROM_GIT ON)
# Pull in Pico SDK
include(pico_sdk_import.cmake)
project(TestProject)
# Initialise Pico SDK
pico_sdk_init()
# Main source files
add_executable(TestProject
src/main.c
)
# Add pico_stdlib library which aggregates commonly used features
target_link_libraries(TestProject pico_stdlib)
# Create map/bin/hex/uf2 file in addition to ELF.
pico_add_extra_outputs(TestProject)
My CMakeLists reloads perfectly fine and the Pico SDK is fetched into the build cmake-build-pico build directory.
I've used the blink example to test if this setup works:

while (true) {
gpio_put(LED_PIN, 1);
sleep_ms(250);
gpio_put(LED_PIN, 0);
sleep_ms(250);
}
#endif
}
When hovering over the import I get a syntax error "'pico/stdlib.h' file not found".
When attempting to build I get the following:

Hello,
I bought a Raspberry Pi 5 recently to use it as a digital dashboard firstly. I want to use Dakboard and tried ways to boot the pi on Kiosk mode with my Dakboard on. Most of the tutorials were still based on the PI 4 and didnt work on the 5. Could you maybe help me?

Raspberry Pi 4 will not display on TV
Hi there, I am fairly new to raspberry pi, and i recently got a Raspberry Pi 4 with 4 GB of ram, and i have installed the 64 bit raspbian OS. However, when i go to connect it to a tv, specifically an LG OLED TV, the TV registers the signal, but nothing is displayed. I've tried both ports, changing OS, and changing the config.txt file to have the code "hdmi_force_hotplug=1"

regarding Raspberry Pi 5 PSU
I bought a Raspberry pi 5, sadly it didn't arrive with an adpater, so I used a mobile charger's adapter for its power and connected it with keyboard, mouse, and a monitor but when I try to boot the raspberry, it turns on for few seconds before shutting down imeditatly. I think it the issue with PS so I bought a charger with 5V and 6A would there be any issues if I use that? because in the website the mentioned that it needs 5v and 5A power. moreover because of my location, there are no official raspberry pi 5 adapters

Pi 4 not booting
I wanted to run some experiments, so I decided to turn on my Pi, only to realise it stopped booting.
The ACT (green) LED doesn't turn on. Only the red LED is on, constantly.
I've been booting off USB for a very long time. I tried reflashing the OS, and tried booting it off on another Pi 4 B+ that I had and it works perfectly there. I've been using the 64-bit raspbian lite image (if this info helps)
I'm using an official Raspberry Pi power supply, so there's no issue with power as well.
3.3V and 5V are not shorted to ground, I've tested that too.
I've tried flashing the rpi-eeprom with an SD card for nothing to happen.
It does boot randomly once every 20-30 tries of power cycle, but shuts off in less than 10-20s from booting up.
I was hoping someone would help me figure out what is wrong with my Pi 4 B+ (2GB). Thanks!

Portainer Installing/Running Correctly when built from template, manual pull issue
I have docker and portainer running on my pi, using the app template from pi hole if I deploy a container using an image everything works fine, I get a published port and can connect and access the app in question with no issues.
I've tried to manually pull one or two images, (Dashy in this case) this works fine, it's when I deploy them as a container, they run fine according to portainer but I don't get a published port listed, so can't access? Any ideas

Separate power supplies for Raspberry Pi and motor driver board
Hi! 👋
I have a Raspberry Pi 5 and this motor driver board: https://www.waveshare.com/rpi-motor-driver-board.htm
The board is connected to a battery pack to power small motors and can supply up to 5V2A to the Pi. Because this is not sufficient for the Pi 5, I need to connect a dedicated power supply to the Pi. I want to avoid any problems that could be caused by having two power supplies connected to each other.
Would disconnecting the 5V GPIO pins (e.g. by wrapping them in electrical tape) be the best/easiest way to use this motor driver board with the Pi 5?

IP CAM connection with Raspberry pi.
Description: Unfortunately I don't have enough information on this subject. I've been trying to connect IP Camera to raspberry pi for 3 days. Either I'm making a hardware or process error. For this reason, I couldn't make the connection. I need to connect on LAN cable. I tried from interfaces such as VLC, OMXplayer, I tried with ssh from the end unit but in vain I could not get the image. I need to transfer the live image.

Pi 5 Docker exit code: 159
Hello,
I purchased a Raspberry Pi 5 8GB. This is my first Pi. When I try running any containers I get an exit 159 error or I just get "no matching manifest for linux/arm/v8 in the manifest list entries".
I installed by doing:
curl -sSL https://get.docker.com | sh
sudo usermod -aG docker $USER
I have stripped my docker-compose.yml and Dockerfile to the bare minimum:
docker-compose.yml:
version: '3.8'
services:

context: .
dockerfile: Dockerfile
image: myapp
container_name: myapp
restart: unless-stopped
tty: true
Dockerfile:
FROM arm64v8/php:8.2-cli
RUN apt-get update -y
When doing "docker compose up" I get:
failed to solve: process "/bin/sh -c apt-get update -y" did not complete successfully: exit code: 159
And it's not just the update command, when I remove it and do anything else I keep getting exit 159. I've tried many different php images.

Auto starting NPM program after reboot
Hey all,
Forgive me am still fairly new to coding/software, recently got my hands on my Pi 5 which I'm loving, following the guide found here - https://github.com/vexorian/dizquetv/wiki/Raspberry-guide I've set up and have dizquetv working on my pi, the only issue is when the device powers off I need to SSH in, start a screen session and restart it with an NPM Start command. Is there a way to automate this, and could someone help me out with some idiot-proof steps?
Thanks in advance 🙂

VNC & HDMI are loosing connection after Pi is running for some time
Hello I am using the PI-4. He is connected through a LAN cable. I am running a python scirpt on it and therefore want him to be always turned on.
When I turn the Pi on, while a HDMI cable is plugged in, he connects normally to my monitor. I go to the settings and turn VNC on and try to connect to the Pi through the RealVNC app. It works. I start the python script and let it run.
I change the signal from the monitor to my PC‘s display port (the HDMI is still plugged in) and use it. I turn the montior off and check back on the Pi at the next day.
I notice that I only get a grey screen as soon as I change the signal from the monitor back to HDMI. I try to connect to the Pi through VNC (what worked the day before) but it doesn‘t work. I just get the error: „The port on which the computer is listening for a connection could not be contacted.“. I can‘t turn the Pi properly of, so is unplug him from the power cable wait shortly and plug him in again.
The Pi boots and connects again to my monitor (the monitor is turned on while I do this). It works again. I go to the settings and look for VNC. It is turned off even though I didn‘t turned it off. Wheb I turn it back on and try to connect to the Pi, it works again.
This repeats every day. I do not know after which time it happens but it is often at the same day.

Monitor turning black after following LCD integration instructions
I followed this instruction to setup my 3.5 LCD screen: https://www.instructables.com/Raspberry-Pi-4B3B-35-Inch-LCD-Touch-DisplayScreen-/
Then suddenly my monitor turns black screen and my LCD only shows white screen. I can't use my RPI since it has black and white screens that's why I can only use its memory card to fix it. What should I do, I already tried editing its config.txt but nothing works. Here is the content of its config.txt:
