Introduction[edit | edit source]
JTAG signals are routed to a dedicated connector (J2) on the BORA Lite PCB. The connector is placed on the top side of the PCB, at the upper-right corner (please see the picture below).
J2 - Connector's pinout[edit | edit source]
J2 footprint mates with Samtec FSI-110-03-G-S connector. The following table reports the connector's pinout:
| Pin# | Pin name | Function | Notes |
|---|---|---|---|
| 1 | DGND | - | - |
| 2 | JTAG_TCK | - | - |
| 3 | JTAG_TMS | - | - |
| 4 | JTAG_TDO | - | - |
| 5 | JTAG_TDI | - | - |
| 6 | FPGA_INIT_B | - | Place external 4.7 kO (or stronger) pull-up resistor to BOARD_PGOOD driven +3.3V supply
For more details please refer to Table 2-4 on 7 Series FPGAs Configuration |
| 7 | FPGA_PROGRAM_B | - | Place external 4.7 kO (or stronger) pull-up resistor to BOARD_PGOOD driven +3.3V supply
For more details please refer to Table 2-4 on 7 Series FPGAs Configuration |
| 8 | FPGA_DONE | - | Place external 300O pull-up resistor to BOARD_PGOOD driven +3.3V supply
For more details please refer to Table 2-4 on 7 Series FPGAs Configuration |
| 9 | N.C. | - | - |
| 10 | 3V3 | - | 3.3VIN enabled with BOARD_PGOOD |
