    7 Gateworks has two models of JTAG programmers:
    8 
    9 '''GW16042''' - uses 14-pin, 0.1" connector for Laguna (GW2387, GW2388, GW2391) boards.
    10 
    11 '''GW16099''' - uses 10-pin, 0.05" connector for Laguna (GW2380, GW2382, GW2383), Ventana, Newport boards.
     7Gateworks supports the following JTAG programmer:
     8 * GW16099 - USB Type A device to 10-pin, 0.05" connector providing 2 USB endpoints:
     9  - FTDI serial console
     10  - FTDI MPSSE JTAG
    1211
    1312Both of these programmers uses the FTDI [http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT2232D.pdf FT2232D ] which has two general purpose 8-bit ports.  The 1st port is configured for JTAG and utilizes the FTDI MPSSE engine. The 2nd port is configured for serial and used for the Serial Console.
