Connecting the Altium USB Adapter to a Xilinx LiveDesign Evaluation Kit
Altium's USB JTAG Adapter enables you to create a JTAG link (incorporating multiplexed Hard and Soft JTAG chains) from your PC (running Altium Designer) to a LiveDesign Evaluation Kit, using a USB connection.
On the PC side, connect the USB JTAG Adapter to a spare USB port on the PC, using the supplied USB cable.
On the Evaluation Kit connect via the use of nine of the flying leads from the supplied JTAG flying-lead cable (10-way IDC – 10 flying leads). The applicable flying leads are connected straight into the relevant pins of the Evaluation Kit's parallel port header (J1S).
The following table lists the flying leads to be used and which pin of the parallel port header they need to connect to.
| Flying Lead color | Connect to Parallel Port Header pin... | Function |
|---|---|---|
| Red | 2 | HARD TDI |
| Blue | 3 | HARD TCK |
| Purple | 4 | HARD TMS |
| Yellow | 7 | SOFT TDI |
| Gray | 17 | SOFT TMS |
| White | 9 | SOFT TCK |
| Green | 10 | SOFT TDO |
| Brown | 13 | HARD TDO |
| Black | 25 | GND |
The Orange flying lead – labeled CONNECT – is floating and can be left unconnected. It is not connected at the Adapter end of the cable.
A shortcut cable or jumper must be added between pin 18 and pin 5.
