STM32L4R9I Fast Program issue

[YNeng.1]

I referenced the example from STM32CubeL4-master and run the Flash_FastProgram example,

but when I execute to this line 

*dest_addr = *src_addr in FLASH_Program_Fast(uint32_t Address, uint32_t DataAddress),

it will go to HardFault Handler, have any ideas?

Thank you and best regards.

Maybe there is a null pointer somewhere ?

[YNeng.1]

But as soon as I entered, I got error (refer to attached) and haven't modify any sample code.

Used STM32CubeIDE1.4.0, does the version of the compiler affect it? Thanks

I don't know, I have just checked FLASH_Program_Fast with an L4R9 discovery board. No problem.

Tested with CubeIDE 1.6.0.

Check option bytes, because there is a warning a the top of the main.c:

/* !!! Be careful the user area should be in another bank than the code !!! */
