The HAT EEPROM is a non-volatile memory chip that sits on a Raspberry Pi HAT and is read via the I²C bus during startup.

  • HAT = Hardware Attached on Top

  • EEPROM = Electrically Erasable Programmable Read-Only Memory

RevPi devices with HAT EEPROM:

  • RevPi Core S/SE from revision 1.1 onwards

  • RevPi Connect series from model RevPi Connect 4 onwards

For devices without HAT EEPROM, the RevPi device configuration must be started manually after reinstalling the image.

▷ Log in to the RevPi via a terminal.

▷ Enter the following command to load the configuration:

sudo bash /etc/profile.d/revpi-factory-reset.sh
