On Raspberry Pi 5 there are dedicated pins for the bootloader SPI EEPROM. This makes it possible to do immediate updates via flashrom. The "current" EEPROM config is the EEPROM config at boot rather than what has just been written to the SPI flash because this is consistent with current behaviour. To use flashrom instead of recovery.bin for bootloader updates set RPI_EEPROM_USE_FLASHROM=1 in /etc/defaults/rpi-eeprom-update BCM2711 On CM4, Pi4, CM4-S, Pi400 config.txt must be modified to disable the analog audio driver which shares the GPIO pins used by the bootloader EEPROM. dtparam=spi=on dtoverlay=audremap dtoverlay=spi-gpio40-45
