Using HAL_FLASH_Program to write a word on a NUCLEO-C031C6

[SJC]

Good Day, 

Is it possible to write a Word using HAL_FLASH_Program? If I use the TypeProgram =  FLASH_TYPEPROGRAM_DOUBLEWORD in the function (shown below) it will write to flash. If I use FLASH_TYPEPROGRAM_WORD it will not write to flash and I receive an error.

HAL_FLASH_Program(uint32_t TypeProgram, uint32_t Address, uint64_t Data);

Regards, 

SJC

Per the reference manual, the STM32C0 series can only program double-words in flash. Writes less than that will fail.

Also there is no FLASH_TYPEPROGRAM_WORD defined in HAL:

Therefore it's not even clear how the code is compiled in that case.
