On board JTAG connector (BoraLite)
On board JTAG connectorEdit
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 pinoutEdit
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 | - | For further details, please refer to PL initialization signals |
| 7 | FPGA_PROGRAM_B | - | For further details, please refer to PL initialization signals
(10 kΩ pull-up resistor is already mounted on BORA module) |
| 8 | FPGA_DONE | - | For further details, please refer to PL initialization signals |
| 9 | D.N.C. | - | RESERVED |
| 10 | 3V3 | - | 3.3VIN enabled with BOARD_PGOOD |
