3.3 Reset Structure
The reset structure is shown in Figure 6 . The power-on reset timing is controlled primarily from the system
PMIC (TPS65917-Q1). There are two push buttons for user-controlled resets. One is the power-on reset
(SW4) for a complete SoC reset. The other is for warm reset (SW5). The warm reset can also be sourced
from the MIPI-60 JTAG/Trace connector.
