Hi @narzul
It seems more a workaround than a real solution.
Erasing the whole flash each time will reduce life of the flash cycle.
Which board you used?

Greetings @fpistm
The board that I'm currently working on is the adafruit stm32f405.
However this is a persistent problem for all stm32f4xx chips when programming using DFU.
It is also a general problem for many other stm32 chips, when programming using DFU.

But if you think that this is something that should be addressed a different place, would you be able to point me in the right direction, so I can write a fix there.

I have the Adafruit F405 and never had this issue same for other series. Which version of cubeprogrammer you used?

I'm running STM32CubeProgrammer v2.16.0

Hi @narzul
Since the script was reworked, see stm32duino/Arduino_Core_STM32#2323 and #97 .

The simplest way is to use the boards.local.txt

# Add erase option to dfu upload method, --erase could also be used
GenF4.menu.upload_method.dfuMethod.upload.options=-v {upload.vid} -p {upload.pid} -e
