Remounting Sd Card

[DeepakY]

I am working with stm32h750xb.  i want to mount and write data at different time interval

i am using fatfs and SDMMC  

If i mount it in main and try to write in loop it is not working it showing error

            so i did both in loop i was able to write and read. but i can do it only once , if i unmount and try to mount again its showing error 

So i want to know how to remount after unmounting 

and also why i am not able to write if i mount in main and write in loop

What is showing error?

What error(s), exactly, is it showing?

What debugging have you done to find the reason for the error?

Give full hardware and software details.

thank you
i found the problem i did not giving delay after unmounting 

i have one more problem

whenever i turn on stm32 the memory card will not get initialized at beginning i need to press reset 3 to 4 times sometimes it does not get initialized after trying for long period also

here is the code 

STATUS stat = RES_OK;

stat= disk_initialize(0);

HAL_Delay(500);

printDriveStatus(stat);

 

while (f_mount(&SDFatFS, (TCHAR const*)SDPath, 1) != FR_OK)

{

 

}
