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? 作者: leung先森 时间: 2017-10-25 11:05
You can turn off all the LDO and DCDC reg for shutdown.
Figure out the RK818 register you need.
