Erase Flash in STM32H730ZB by flash word.

[BPanc.1]

Hi,

I want to implement custom bootloader in STM32H730ZB, It has 128KB of Flash and only one sector. If I want to load image using bootloader then, I need to erase particular portion of flash.

Is there any support to erase flash by flash word? If I erase whole sector then it will not allowed as bootloader is running in same sector.

Thanks
