Question
Fatfs f_mount and f_getfree
I am using NUCLEO H743ZI2 with Fatfs and FreeRTOS V2. The program is working now, but I have one issue on free size of SD card. After I use f_mount to mount my SD Card, In structure FATFS variables, last cluster and free cluster are not correct. If I use f_getfree, I am able to get correct free cluster, but after FATFS variable passing through f_getfree is updated inside function f_getfree, I can't use f_open function. However, after I use function f_open, then I use f_getfree to get free cluster, everything is working fine.
Does anybody know what is happen? how can I get correct free size when I use f_mount to update correct free cluster?
