2.2.2 Power Status LEDs

Multiple power-indication LEDs are provided on-board to indicate to users the output status of major supplies. The LEDs indicate power across various domains as shown in the table below.

Table 2-2 Power Status LEDs(1)
Name Default Status Operation Function
LD1 OFF Type-C CC Logic Power Error Indication. Type-C connection not supplying 5 V @ 3 A
LD2 ON VMAIN_12V0 Power indicator for VMAIN 12 V supply
LD3 ON VSYS_3V3_LDO1 Power indicator for PMIC LDO 3.3 V supply
LD4 ON VSYS_1V2_PG Power Good indicator for 1.2 V supply rail
LD5 ON VSYS_TA_3V3 Power indicator test automation header 3.3 V supply
LD6 OFF USER_LED0 User Programmable Red LED
LD7 OFF USER_LED1 User Programmable Green LED
LD8 OFF PMIC_SAFE_OUT2 Safety Error indicator output from PMIC
LD9 OFF XDS110_PROG_STAZ1 LED glows after XDS configuration
LD10 OFF XDS110_PROG_STAZ2
LD19 OFF SAFETY_ERROR Safety error output status pin from AM263Px
LD20 ON VCC_1V8_LDO4 Power indicator PMIC LDO 1.8 Vsupply
LD21 ON VDD_5V0_LDO3 Power indicator for PMIC LDO 5.0 V supply
LD22 ON VSYS_3V3_LDO2 Power indicator for PMIC LDO 3.3 V supply
(1) LD[19:22] are not included in the E1 version of the Control Card.
