USB DFU STM32H745I-DISCO can't write / erase internal flash over 0x08100000.

[Ade1]

I have the STM32H745I-DISCO board. Using STM32CubeProgrammer and STLink the internal flash can be erased and programmed OK however erasing / programming bank 2 using DFU fails even after full chip erase using STLink. Are there additional steps needed to write bank 2 with DFU?
