Hello
Built a Preen FM2 tonight including the F405. Beaut¡uful design!
Before flashing the bootlader (OSX) I type dfu-uyil -l and get this, so I guess there is connection with the STM
dfu-util -l
dfu-util 0.9
Deducing device DFU version from functional descriptor length

Now, when I try to flash bootloader 1.11
[~] marcos% dfu-util -a0 -d 0×0483:0xdf11 -D p2_boot_1.11.bin -R -s 0×8000000
I get:
dfu-util 0.9
dfu-util: Invalid DFU suffix signature
dfu-util: A valid DFU suffix will be required in a future dfu-util release!!!

Any idea of what the problem is?
Thanks a lot
