S1 is located on the top-left corner of the EVM. This switch is a push-button that pulls the HRESET pin (39) of the TPS65988 high when pressed. Releasing the push-button pulls HRESET low again, and the TPS65988 goes through a soft reset, which consists of reloading firmware (FW) from RAM. If a valid configuration is present in the RAM, the TPS65988 does not reload the configuration from the external flash. Figure 5-10 highlights these features.
