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
