SDIO DETECT is changed to PD5 which was earlier PF3

[Victorheca01]

Hi, All

    my file system is working with the eval board of STM32U575I-EV.   

    However, run the same software with NUCLEO-U575ZI-Q, file system doesn't work.

    I found that SDIO DETECT is changed to PD5 NUCLEO-U575ZI-Q which was  PF3 on STM32U575I-EV.

    How can I change the SD card pin definiton in IOC? Thanks in advance.

Best Regards

Victor

look for

fatfs_platform.h

/* USER CODE END Header */
/* Includes ------------------------------------------------------------------*/
#include "stm32h7xx_hal.h"
/* Defines ------------------------------------------------------------------*/
#define SD_PRESENT ((uint8_t)0x01) /* also in bsp_driver_sd.h */
#define SD_NOT_PRESENT ((uint8_t)0x00) /* also in bsp_driver_sd.h */
#define SD_DETECT_PIN GPIO_PIN_5
#define SD_DETECT_GPIO_PORT GPIOD
/* Prototypes ---------------------------------------------------------------*/
uint8_t BSP_PlatformIsDetected(void);

Hi, NNapi

   Thank you for quick response. I appreciate it very much.

   However, my source code don't has fatfs_patform.h. I also search the source code and cannot find the definiton of SD_DETECT_PIN in my package. please advice.

Thanks in advance.

do search for PF3 , it is defined somewhere and change to PD5

I searched the whole project, but no PF3 string found.

Does anyone use Fx_File_Edit_Standalone example as baseline for file system? This works for another version of Eval board, but with NUCLEO-U575ZI board, I have to change SDIO DETECT   to PD5 from PF3.

Thanks in advance.

I have no clue what you are doing, did you generate the new code in CubeMX ?

did you check main.h file

#define SDCARD_DETECT_Pin GPIO_PIN_0

#define SDCARD_DETECT_GPIO_Port GPIOI
