Hi all,
I'm running into a persistent boot issue with my Raspberry Pi 5 (8GB model). Upon powering up, I get the following message on screen:
SD: card not detected
USB boot requires high current (5 volt 5 amp) power supply.
To disable this check set usb_max_current_enable=1 in config.txt
Setup Details:
Model: Raspberry Pi 5 (8GB)
Boot Device: Samsung 32GB microSD card (Class 10)
OS: Raspberry Pi OS (32-bit), flashed using Raspberry Pi Imager
Power Supply: Official CanaKit 5V 5A USB-C PSU
Display: HDMI connected
No USB drives or HATs connected during testing
What I’ve Tried:
Reformatted and re-flashed the SD card multiple times using Raspberry Pi Imager.
Verified the SD card works fine in my PC (it mounts and reads properly).
Tried reseating the SD card carefully multiple times.
Powered the Pi with no peripherals connected other than HDMI.
Same issue persists: "SD: card not detected"
As a fallback, tried to boot from a USB device, but then get the current limit warning unless I press the power button to temporarily enable usb_max_current_enable.
Next Steps I’m Considering:
Flashing the bootloader recovery image to a USB stick to reinitialize the EEPROM in case it’s corrupted.
Testing another microSD card (though the current one is verified to be working).
Has anyone encountered this behavior with the Pi 5?
