STM32Cube_FW_F4_V1.11.0

 I have enabled 3 FATFS: SDRAM, SRAM and SDCard Bug 1: Using FreeRTOS and FATFS and USB-Desice on stm32F429

double

generates   MX_FATFS_Init();  MX_USB_DEVICE_Init(); in ''main()'' and in Task ''void StartDefaultTask(void const * argument)'' - one time would be enough ==> 2 calls of MX_FATFS_Init() ==>  6 calls of ''FATFS_LinkDriverEx()'' in ''ff_gen_drv.c'' Bug2: Array check in FATFS_LinkDriverEx in ''ff_gen_drv.c'':  the array[_VOLUMES] index test in Line 55 is      if(disk.nbr <= _VOLUMES) correct is   if(disk.nbr < _VOLUMES)  Result: Access behind the Array is made --> System overrides nextVariables and crashes some times later. #!bug #!stm32-!cubemx

Dear user,

The issue is known and logged against STM32Cube firmware package on ff_gen_drv.c but has not been fixed yet.
