I have been trying to port the nz32-sc151 port to riot witch uses dfu for programming. I’ve seen one board that also uses dfu in RIOT, the spark-core. But for some reason the spark-core dfu adaptation doesn’t seem to work. Also I’m not really sure why that specific board uses openocd in its makefile since it’s supposed to flash via dfu. My question would be what can be done in RIOT to flash dfu, is it possible to add dfu support? generate dfu files? flash dfu files? how much of this has to be done manually? Thanks in advance for your help.
