Welcome to Help & troubleshooting
Pi will not boot? SBC dropping off the network? GPIO doing nothing at all? Ask here. Someone has probably hit the same wall before.
What belongs here
• Boot failures, blank screens, blinking LEDs and kernel panics
• Networking, SSH, Wi-Fi and headless setup problems
• GPIO, HATs, displays and camera modules
• Software installs, updates gone wrong and storage problems
What goes elsewhere
• Finished projects: Projects & builds
• Chat and buying advice: General discussion
• Microcontrollers such as the Pico: ESP32 & microcontrollers
How to ask so people can help
1. Board: the exact model and RAM, or for other SBCs the maker, model and revision
2. Operating system and version, and how you flashed it
3. Power supply: what it is and what it is rated for
4. Storage: SD card or SSD, brand and size
5. Anything connected: HATs, displays, USB devices, and a wiring diagram for GPIO
6. The commands or code you ran, pasted as text and kept to a minimal example
7. The result you expected versus what actually happens, with full error messages or log output
8. What you have already tried
Quick checks first
• Undervoltage is behind a huge number of strange problems. Try a known-good supply rated for your board.
• Reflash the card, or try a different one. Cards fail more often than boards.
• Watch the power and activity LEDs; their blink patterns often point to the fault.
• Check GPIO wiring against a pinout, and remember the pins are 3.3 V only and need a shared ground.
• For headless setups, confirm SSH and Wi-Fi were configured before first boot.
Before you paste logs
Remove passwords, Wi-Fi keys, API tokens and public IP addresses.
When it is fixed
Post the fix so the next person benefits.
Board rules
• No malware, nothing piracy-friendly, and no selling or paid services.
• Safety warnings on batteries and mains are part of the rules. Leave mains wiring to qualified people.
The house rules apply: be kind, English only (other languages are translated automatically), no spam, no keyboard mashing and no self-promotion spam. Use Report if you spot a problem. This thread is locked, so start your own thread for help.
