Reset Structure
The reset structure is shown in
. The power-on reset timing is controlled primarily from the system
power ICs (TPS65917/LP87565). There are two push buttons for user-controlled resets. The power on
reset pushbutton (SW9) provides a complete/cold reset to the SoC. The warm reset pushbutton (SW8)
provides a warm reset to the SoC. The warm reset can also be sourced from the MIPI-60 JTAG/Trace
connector.
The SoC itself provides a reset for all its peripherals (RSTOUT).
