DD
3. Hardware Setup
A USB Debug Adapter or EC2 Serial Adapter may be used to connect through the JTAG interface as shown in
DD
1. Connect the 10-pin ribbon cable from the debug adapter to the JTAG interface.
2. Connect the other end of the debug adapter to the appropriate port on the PC.
3. Connect an external power supply to the device by connecting the grounding cable to pin DGND on J6 and the
power cable to pin V
.
