Way of system reset by software

I would like to assert system reset by software.

I intend to use Software Reset Signal(SRS) in Watch dog Control Register, But errata report mentions that watchdog timeout or software trigger will not reset the SOC.

Is there other way to assert system reset by software?

Hi Toshiharu

>Is there other way to assert system reset by software?

not, sorry. So recommendation is to remove power (Voltage source) to
all components on the board in the event of a processor reset.

NXP reference boards were designed to remove power (Voltage source)
to all components on the board in the event of a processor reset.

For example on i.MX7D Sabre SD schematic SPF-28590 p.23 

it is done with signal PMIC_PWRON, U37.

Best regards
igor
