Power ON / OFF issue of fireprime board.
5V is supplied to the DC adapter or USB connection.
After setting DEV_OFF bit, the RK818 restart automatically.
The ON_SOURCE_REG (Address AEH) is 0x40 after the automatic restart which says that the RK818 was started by ON_PLUG_IN event.
Is there a possibility to configure the RK818 that it will not start automatically in this case?

You can turn off all the LDO and DCDC reg for shutdown.
Figure out the RK818 register you need.
