STM32H757 'FLASH_TYPEPROGRAM_BYTE' undeclared (first use in this function)

Hello,

I am getting an error in HAL_FLASH_Program, error: 'FLASH_TYPEPROGRAM_BYTE' undeclared (first use in this function); did you mean 'TYPEPROGRAM_BYTE'?

why is this programming type not supported FLASH_TYPEPROGRAM_BYTE. Can anyone suggest a solution for this issue.

Attached the screenshot below,

Thank you in advance for your assistance!

This is not a bug. Flash can only be written to in double-words. This is due to the ECC calculation.

Solution is to write the entire flash word padded with 0x00 or 0xFF.
