|
|
* 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.
