I’ve been trying to update the firmware on the Core since that appears to fix the analogRead issues people have been having. I’ve followed all of the instructions outlined on the Spark Firmware page, but am getting stuck at the end of the process.
I’ve successfully put the Core in the right mode (flashing yellow) and run
dfu-util -l in the Terminal window. What should be coming up according to the instructions is
Found DFU: [1d50:607f] devnum=0, cfg=1, intf=0, alt=0, name="@Internal Flash /0x08000000/20*001Ka,108*001Kg" Found DFU: [1d50:607f] devnum=0, cfg=1, intf=0, alt=1, name="@SPI Flash : SST25x/0x00000000/512*04Kg"
However, no devices are listed and the only thing that I receive is

Any suggestions on how to get the Terminal to list the Core? I have tried both USB ports on my Macbook and that hasn’t helped. I am running OS X 10.9.2.
