STM32F407 Fatfs Causing the Time-based source to be in Hung State.

[Bilal1]

I am using the Fatfs to mount the SD Card. As soon as f_mount is called it puts the ticks in hang up state causing the HAL_Delay to be in infinite loop resulting in device hang up.

I am using the STM32F407-Dicovery Board

For SD Card I am using the SPI1 of the board.
