User LED2 mapping bug on Nucleo-H753ZI

[KishoreK31]

Hello, 

 

Began learning STM32 MCUs with my Nucleo-H753ZI board and I think I found a bug. 

The IO configurator on CubeIDE thinks user LED2 is on PB7 and is blue coloured. I'll paste the code it generates below. But in fact, the user manual UM2407 says user LED2 is on PE1 and is yellow coloured, which is indeed correct. 

Generated code from CubeIDE for Nucleo-H753ZI:

#define LED2_PIN GPIO_PIN_7
#define LED2_GPIO_PORT GPIOB

 Appears to be a bug that should be fixed in the BSP.

Hello @KishoreK31 and welcome to the ST community,

It will be escalated internally for analysis and an eventual analysis. Internal Ticket 218959 has been submitted which is not accessible by the community users.

Thank you for your contribution.

typedef enum
{
 LED1 = 0,
 LED_GREEN = LED1,
 LED2 = 1,
 LED_YELLOW = LED2,
 LED3 = 2,
 LED_RED = LED3,
 LEDn
}Led_TypeDef;
#else /* USE_NUCLEO_H743ZI || USE_NUCLEO_H753ZI */
typedef enum
{
 LED1 = 0,
 LED_GREEN = LED1,
 LED2 = 1,
 LED_BLUE = LED2,
 LED3 = 2,
 LED_RED = LED3,
 LEDn
}Led_TypeDef;
#endif

There are no "NUCLEO_H753ZI", maybe that's the reason.

The OP is not using the BSP driver for this board but rather the CubeMx configuration that configures the pins by default for this board.
