FAIL.txt "The transfer timed out"
I am on an OSX machine. I plugged in the mk20 device with the BLE nano plugged into it. When I plug it in I am told that the drive name is DAPLINK... Could this be a problem? IDK. Then I ran the following command "dd if=blenano_mk20dx_interface_20140912.bin of=/Volumes/DAPLINK/dst_firmware.bin conv=notrunc " I unplug the device, and when I plug it back in there is a file called FAIL.txt that states: "The transfer timed out. " How do I fix this?
DAPLINK name is correct. If you're just copy and pasting the file (not via dd) does it do something differently? You should not have to unplug / replug the device, should restart when flashing is complete. You sure the Nano is plugged in correctly in the MK20 board?
