As shown in
, once the T-Core is connected to the JTAG interface of the external FPGA
board, the T-Core board automatically detects the connection and switches the JTAG chain from the
Intel MAX10 FPGA to the external JTGA header, and connected to the JTAG interface of the
external FPGA board. Implement a USB blaster II function.

In addition, users should note that for externally connected JTAG interface,
the
T-Core can
support I/O standard voltage range from 1.2V to 3.3V
. If it is out of this range, it may not be
able to work properly or cause damage.
The following example demonstrates that use the T-Core to connect the JTAG interface of the
Terasic's DE10-Pro Stratix 10 development board and program .sof file into the FPGA via JTAG
interface.

Connect the flat ribbon cable to the J1 of the T-Core board, as shown in
. The red line
represents the connection line of pin 1, which needs to be connected to the pin of J1.
