Power Status LEDs

Multiple power-indication LEDs are provided onboard to indicate to users the output status of major supplies. The LEDs indicate power across various domains.

Table 2-3 Power Status LEDs
Name Default Status Operation Function
D7 ON VSYS_5V0 Power indicator for supply 5V voltage
D14 ON VSYS_3V3 Power indicator for generated 3.3V voltage
D16 ON VSYS_2V5 Power indicator for generated 2.5V voltage
D12 ON VDD_1V2 Power indicator for generated 1.2V power-good voltage
D15 ON VSYS_1V8 Power indicator for generated 1.8V voltage
D13 OFF WARMRSTN Power indication for WARMRSTN
DS2 OFF SAFETY_ERROR Power error indication for SAFETY_ERROR
D1 OFF XDS_PROGSTAZ1 LED will glow after micro-B connection is made
DS1 OFF XDS_PROGSTAZ2 LED will glow to indicate communication over JTAG
Note: DS2 LED that correspond to SAFETY_ERROR is always ON.
