Is it possible to program one byte per time on STM32H7

[Lifei Yan]

Is it possible to program one byte per time on STM32H7.If it is supported, how should I do? Is there any demo?

Thank you

While it's theoretically possible to program a partial FLASH word (which is 256 bytes), further programming parts of the same word is more or less impossible as it most probably results in incorrect ECC.

Read the FLASH chapter in RM, concentrate on FLASH program operations subchapter.
