hard fault during flash programing

[Mohammadreza-Azizi]

hi. i am trying to save a data into stm32h7b0vbt6 flash memory. so i have used HAL_FLASHEx_Erase to erase one of the sectors and HAL_FLASH_Program to program it. 

it works and flash will be programed.

but when debuging, code gets stuck to while of the void HardFault_Handler(void) and it doesn't continue. how i fix it?

At 8K in you're probably erasing the application itself.

Use a sector at the END of memory, not the front.

Look at what is actually reported by the Hard Fault.. the memory address and the processor registers.
