Power
Power up:
*Power switch pressed
*System Pass-FET turns on
System
Pass-FET
*5V supply rises within 3ms and asserts POWER_GOOD
*3.3V regulator output rises
*If the power button continues to be held down,
*Signal "PWR_EN" rises to >=1.4V
(it has 900k
(Vih_min of PMIC input pin)
*System-on-module powers on when:
(the open drain output goes hi-z))
*System-on-Chip asserts PWR_HOLD a few seconds later, latching module power
Power down:
*System-on-Chip writes shutdown command to PMIC
(see PMIC datasheet p29) on, as well as the System Pass-FET
to PMIC
*POWER_GOOD is pulled up to 3.3V
*Once power switch is released, PMIC_PWRON and POWER_GOOD return to hi-z
*Signal "PMIC_PWRON" pulled to ground through 50k
*Further button presses/releases have no impact on PMIC, but they are still
also passed to SoC via
the PMIC on net PWR_KEY
*Master Pass-FET turns off
Reset:
USB 2.0 headers
*active RESET signal pulls PWR_EN low, turning off most supplies generated by PMIC

Recovery (boot-loader access:)
*http://radxa.com/Rock2/square_bb/loader_mode
*With board powered on, connect USB OTG port to host PC
*Assert RECOVERY for 5 seconds
*Assert and then unassert Reset (mininum assertion time should be short, but it is TBD)
1.8V LDO
Delay
Reset
from external PCB
keep System Pass-FET on for at least 1s after
every power button or reset button
press/release event
asserted a few secs
*Delay circuit is charged, keeping System Pass-FET
powered for ~5s after button release
from external PCB
Active: drive to 3.3V
Inactive: pull low or go hi-z
*Delay circuit is charged, keeping System Pass-FET
powered for ~5s after button release

Active: pull low
Inactive: hi-z
Active: pull low
Inactive: hi-z
passed to SoC and can have a software-defined function
*PWR_HOLD goes unasserted as System-on-Chip becomes (mostly) unpowered
*RESET button is released, so PWR_EN is no longer actively pulled low
*System-on-Chip asserts PWR_HOLD ~1s later, latching module power +
*unassert RECOVERY
