Appendix B. Programming Using JTAG Flywire Connections
The MachXO2 Dual Sensor Interface Board includes provision for the flywire-connected programming header J3.
The pins for the J3 header are not installed, as typical use of the board is through the USB download. To use a fly-
wire JTAG connection rather than the built-in USB download at J13, the user will need to first acquire the flywire
download cable and connect it to J3. The pinout for J3 is provided in Table 11.
Important Note: The board must be un-powered when connecting, disconnecting or reconnecting an ispDOWN-
LOAD cable or USB cable. Always connect an ispDOWNLOAD cable’s GND pin (black wire), before connecting
any other JTAG pins. Failure to follow these procedures can in result in damage to the LatticeECP3 FPGA and ren-
der the board inoperable.

Requirements:
• PC with Lattice Diamond design software version 1.3 (or later), installed with appropriate drivers (USB driver for
• Any ispDOWNLOAD or Lattice USB Cable (pDS4102-DL2x, HW7265-DL3x, HW-USB-2x, etc.).
USB Cable, Windows NT/2000/XP parallel port driver for ispDOWNLOAD Cable). Note: An option to install these
drivers is included as part of the ispVM System setup.
