Hi Koenraad,

I'm using "DfuSe USB device firmware upgrade STMicroelectronics extension"
from ST. You can download it from this link.

 I compiled the project with IAR, got a HEX file that I uploaded to my
microcontroller using a STLink2 (JTAG).

Now when you hold the button and power up the micro, it will enter bootload
mode and allow you to upload new firmware via the USB. The only requirement
is that your new project will start at 0x08003000 since the bootloader
resides at the beginning.

As from a FPC view, you only need to change the flash stat offset as I had

The link I posted has all the required software, docs and drivers you will

Please ask if you have any other questions.
