Overview
In this tutorial, I am going to show you how to program TIAO Xilinx XC2C64A CoolRunner-II CPLD Dev Board (Reset Glitch) using TIAO USB Multi-Protocol Adapter (TUMPA). This method applies to all devices supported by xc3sprog.
The process is fairly straightforward.
Required Hardware and Software
- TIAO USB Multi-Protocol Adapter (TUMPA)
- Patched xc3sprog, download from here
- Supported CPLD, we use TIAO Xilinx XC2C64A CoolRunner-II CPLD Dev Board (Reset Glitch) as our example.
- (Optional, only needed if you are programming CPLDs) Xilinx CPLD map files. It is part of Xilinx Labtools (labtools\labtools\xbr\data), or you can download from here
Software Installation
- Since I am going to program CPLD, download CPLD's map file from here. Unzip to a directory, e.g. d:\dev\.
- Install drivers for TUMPA. Instruction for Windows XP: How to install TIAO USB Multi Protocol Adapter Driver on Windows XP, Vista and Windows 7: How to install TIAO USB Multi Protocol Adapter Driver on Windows Vista or Windows 7. For Linux, you can get the driver here: FTDIDXX Drivers
- Download TIAO patched xc3sprog from here, unzip it to a directory. In my example, I unzipped to d:\dev\ directory. After you unzip it, a directory TIAO-xc3sprog will be created. The Windows applications are under win32, Linux applications are in linux32.
Hardware preparation
In our example, we use XC2C64A (RGH Hack Dev Board), it takes +3.3V power. TUMPA provides both +5V and +3.3V, thus a separate power supply to power up CPLD is not needed.
Connect TUMPA's TDI, TDO, TCK, TMS, +3.3V and GND pins to our XC2C64A dev board's TDI, TDO, TCK, TMS, +3.3V and GND respectively using the supplied female to female flexible cable.
The pinout of the JTAG connector (Complete pinout is here: TIAO USB Multi Protocol Adapter User's Manual#20 PIN JTAG Connector):
| Pin # | Description |
|---|---|
| 5 | TDI |
| 7 | TMS |
| 9 | TCK |
| 13 | TDO |
| 4, 6, 8, 10, 12, 14, 16, 18, 20 | GND |
The +3.3V and GND pin can be obtained from TTL Level Serial Connector.
Pinout of TTL Level Serial Connector (Complete pinout: TIAO USB Multi Protocol Adapter User's Manual#TTL Level Serial Connector):
| Pin # | Description |
|---|---|
| 9 | +3.3V |
| 11, 12 | GND |
The pinout of our XC2C64A Dev Board (JTAG pins and V3.3, GND are on P1):
| Pin # | Description |
|---|---|
| P1.1 | TDI |
| P1.2 | TMS |
| P1.4 | TCK |
| P1.3 | TDO |
| P1.11 | GND |
| P1.12 | +3.3V |
Now connect TDI, TDO, TCK, TMS, GND and +3.3V together:
Program CPLD
Copy the trinity.jed (or your jed file) to TIAO-xc3sprog\win32 or linux32 directory. In my case, I copied it to TIAO-xc3sprog\win32 directory as I am testing on Windows 7 64bit.
Connect TUMPA to PC using a USB cable:
Now, open a dos prompt windows, change directory to where you have unzipped TIAO-xc3sprog\win32, run the following command to detect JTAG chain:
xc3sprog -c tumpa -L
The -c tumpa option is to specify using TUMPA JTAG adapter. The -L option is to tell xc3sprog to use FTDI's D2xx driver instead of LibUSB and LIBFTDI. This is recommended.
Your CPLD should be detected:
