stm32f446re FLASH_TYPEPROGRAM_DOUBLEWORD doesn't work

I am using the FLASH_EraseProgram  example to write/read from the flash memory.

When I am trying to write the flash with double words(64 bits) and then read the values, the values doesn't save in the flash. I don't get any errors.


If I am doing the same thing with a word(32 bits - FLASH_TYPEPROGRAM_WORD) it works.


What am i doing wrong ? What could be the problem ?
