Q: Raspberry Pi 5 reports insufficient current?

A: When the Raspberry Pi 5 boots up, it detects the PD protocol on the Type-C port. If no PD protocol is detected, the system will display the following prompt and limit the output current to 3A.

Solution: Modify the EEPROM configuration to remove the current limit and allow up to 5A.

  1. Open the EEPROM configuration editor:

    sudo rpi-eeprom-config --edit

  2. Add the following line at the end of the configuration file, save and exit:

    PSU_MAX_CURRENT=5000

  3. Reboot the Raspberry Pi. The prompt should disappear, indicating the setting has taken effect.
