Raspberry Pi4 bootloader EEPROM release notes
2019-09-10 - Git f626c772
- Configure ethernet RGMII pins at power on. This is a minor change which which may improve reliability of ethernet for some users.
2019-09-05 - Git d8189ed4 - (BETA)
- Update SDRAM setup to reduce power consumption.
2019-07-15 - Git 514670a2
- Turn green LED activity off on halt.
- Pad embedded config file with spaces for easier editing by end users.
- Halt now behaves the same as earlier Pi models to improve power behavior at halt for HATs.
- WAKE_ON_GPIO now defaults to 1 in the EEPROM config file.
- POWER_OFF_ON_HALT setting added defaulting to zero. Set this to 1 to restore the behavior where 'sudo halt' powers off all PMIC output.
- If WAKE_ON_GPIO=1 then POWER_OFF_ON_HALT is ignored.
- Load start4db.elf / fixup4db.dat in preference to start_db.elf / fixup_db.dat on Pi4.
- Embed BUILD_TIMESTAMP in the EEPROM image to assist version checking.
2019-05-10 - Git d2402c53 (RC2.1)
- First production version.
