Hi,

I have a CubeIDE peroject with STM32H753ZI, C++, TreadX, Nucleo-H753ZI board. This device has 2MB Flash and 16 sectors of 128K each. 16 x 128K = 2MB but the generated stm32h7xx_hal_flash_ex.h includes only 8 sectors. Only OB_WRP_SECTOR_0-7 are defined. Whaere is the rest?

Best regards,

Osto

    Sectors 0-7 are per bank. STM32H753 has two banks, 8 sectors each.
