Core-firmware setup

Firmware
1

I got through all the steps mentioned in:

Until the very end. I found that “sudo dfu-util -l” was needed to get the same output as the README mentions. But then when I run “sudo dfu-util -d 1d50:607f -a 0 -s 0x08005000:leave -D core-firmware.bin”, I get the response:
“invalid dfuse address: 0x08005000:leave”

Any thoughts on what I’m missing? My spark core is currently flashing yellow, as mentioned.

Thanks!!

Ah, updating dfu-util was the answer:

I got to .7 by building the source mentioned here: http://dfu-util.gnumonks.org/build.html
