LED toggling

[Gopals0108]

I am using NUCLEO-U575ZI-Q eval board. I am trying to blink RGB LEDs. But RED LED which is connected GPIOG pin 2 is not toggling.

Have you used commands to enable the VDDIO2 power to the GPIOG bank?

No code shown

HAL_PWREx_EnableVddIO2();

 

#define LED3_PIN GPIO_PIN_2
#define LED3_GPIO_PORT GPIOG
#define LED3_GPIO_CLK_ENABLE() __HAL_RCC_GPIOG_CLK_ENABLE()
#define LED3_GPIO_CLK_DISABLE() __HAL_RCC_GPIOG_CLK_DISABLE()

I had the same issue. Adding a call to HAL_PWREx_EnableVddIO2() fixed it. Thank you.

Have you checked (board User Manual & Schematics) that there's nothing else on the board occupying those pins?
