The F429 version of the Octopus Pro v1.0 can be flashed via DFU over the usb-c port, but unlike the F446 version of the same board DFU-UTIL is not able to reboot the board in DFU mode and flash it.

dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!
Deducing device DFU version from functional descriptor length
dfu-util: No DFU capable USB device available
The only way to make the F429 visible to dfu-util (latest compiled version 0.11 from source, i had no luck with the stock 0.9 that comes with debian) is to jump the Boot0 high and reboot the board via reset, in that way dfu-util works.

It is probably just a matter of having the F429 bootloader updated so that dfu-util can reboot the board in DFU mode and flash it, verify and reboot in normal mode without any physical interaction, like the F446 already does.
