Flashing into partition

[aravindpv]

Hi, I have been trying to implement a logic to flash the updated firmware on top of existing with established DFU mode and using stm32cubeprogrammer. Where I chosen bin file for flashing and I provided the starting address as well. For confirming I have added enough debug prints and from that i never seen the erase function never being called when push the new update through USB.

pls see the logs
