* board_info: Use the Ethernet PHY address probed by the bootloader Use the Ethernet PHY address supplied by the bootloader in preference to the static configurations defined in start4.elf * pi5: Fix overwrite of cache EEPROM config in secure-boot mode See: https://github.com/raspberrypi/rpi-eeprom/issues/719 * Check for SD card overcurrent on Pi5, Pi500 and Pi4 Before booting, the bootloader now checks the SD power switch overcurrent signal. The overcurrent signal occurs if the SD card is damaged and has a short circuit which will cause it to get hot. If an over-current condition is detected the bootloader switches off power to the SD card and waits five seconds before probing the SD card again. This error is displayed on the diagnostic screen, the UART and the activity LED (1 long, 2 short) flashes. The check can be switched to a non-blocking warning by setting SD_OVERCURRENT_CHECK=0 in the bootloader config. * Add a new error code pattern for SD overcurrent Add a new error pattern (1 long, 2 short) to signal SD card overcurrent. * Enable RTC wakeup from POWER_OFF_ON_HALT=0 * Improve HAT+ current handling In shipping firmware, the current_supply value is only being used in the case of a normal (non-stacked) HAT+, but that is unnecessarily restrictive. Also, the presence of MODE0 and MODE1 power HATs is not reflected in the value of max_current. See: https://github.com/raspberrypi/linux/pull/6678
rpi-eeprom
This repository contains the scripts and pre-compiled binaries used to create the rpi-eeprom package which is used to update the Raspberry Pi 4 and Raspberry Pi 5 bootloaders EEPROM images.
Support
Please check the Raspberry Pi general discussion forum if you have a support question.
Reset to factory defaults
To reset the bootloader back to factory defaults use Raspberry Pi Imager to write an EEPROM update image to a spare SD card. Select Misc utility images under the Operating System tab.
