2.2.2 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 as shown in Table 2-1.

Table 2-1 Power Status LEDs
Name Default Status Operation Function
LD1 OFF SoC_GPIO1_49 User Test LED
LD2 ON VDDR_CORE Power indicator for VDDR CORE
LD3 OFF XDS Data Red LED glows during XDS110 data transaction
LD4 ON PMIC_RSTOUT Power Good indicator for PMIC
LD5 ON 1 XDS Power XDS Power Green LED
LD6 ON VCC_3V3_SYS Power indicator LED for VCC_3V3_SYS
LD7 ON 1 VCC_3V3_FT4232 FT4232 Power LED
LD9 OFF VBUS_TYPEC2 Indicator LED for Type_C USB connector 2
LD10 OFF IO_EXP_TEST_LED User Test LED for 3V3 IO expander
LD13 OFF VBUS_TYPEC2 Indicator LED for Type_C USB connector 2
LD14 OFF VMAIN_EN Power Delivery Error Indicator, Type-C connection not supplying minimum 15W (5V at 3A)
  1. ON as long as micro-USB cable is connected.
