v10 v11 5 5 '''To use the JTAG software with the Ventana boards, please see the [wiki:jtag_instructions JTAG Software Page]''' 6 6 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. 7 Gateworks 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 12 11 13 12 Both 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. 14 13 15 == GW16042 JTAG dongle ==16 The diagram below shows the signal mapping for the 14-pin connector:17 18 [[Image(GW16042_14pin_JTAG.PNG, 300px)]]19 14 20 15 == GW16099 JTAG dongle == … … 54 49 c.
