Nucleo board blinking red light3/2/2024 Type “LED” in the Find field and check that LD2 (green Led) is enabled to PA5 pin as GPIO_Output.To verify that LD2 is set to GPIO_Output mode: This example shows the use of the green LED pin LD2 present on the NUCLEO-L476RG board as GPIO_Output. To see alternate pins for a signal, drag and drop the signal to a pin while keeping the Ctrl key pressed. (To configure LED pins, check in the STM32 Nucleo-64 boards User Manual and STM32L476xx Datasheet which LED pins to use). When a board is selected, STM32CubeMX allows automatically the pinout setting for the board with the pin assignments for the communication interfaces, LEDs, and other functions. The corresponding pins PA13 and PA14 are assigned and configured automatically.
