Why does STM32L0 Not Support TYPEPROGRAM_BYTE/ FLASH_TYPEPROGRAM_BYTE

The HAL documentation

http://www.st.com/content/ccc/resource/technical/document/user_manual/41/78/8e/63/f9/32/44/12/DM00113898.pdf/files/DM00113898.pdf/jcr:content/translations/en.DM00113898.pdf

  seems to correctly mention, that for HAL_FLASH_Program(), only TYPEPROGRAM_WORD is supported. CubeMX also generates TYPEPROGRAM_BYTE but FLASH_TYPEPROGRAM_BYTE remains undefined. My question is, why is this programming type not supported on L0?#cube-hal #stm32l0 #flash-storage

Hello

Hoppe.Thomas

,

In STM32L0 reference manual, it is specified that programming in the Flash memory can only be performed by word or half-page.

Therefore L0 Flash driver does not support byte programming, and can not be modified to support it.

Kind Regards,
