Here are shown the connection and disconnection procedure for the USB Blaster programming device. The board in the videos is different but the procedures will apply to the JTAG and AS connectors of "The Thing" too.

USB Blaster connection procedure

After that you are ready to upload the configuration into the FPGA you must follow the suggested steps as described in the Usb Blaster User Guide:

  1.  Check that the target (the board) is not powered;
  2.  Connect the Usb-Blaster programmer first to the Workstation USB;
  3.  Connect the JTAG cable to the target;
  4.  Power the target. This means connect the board USB connector to an other USB port on the Workstation.

Remember that the USB Blaster can't power the target. The power comes from the USB connector.
