Kintex-7 FPGA KC705 Evaluation Kit - Unable to Initialize JTAG chain when XM105 Debug FMC card connected


When the XM105 Debug FMC card is connected on the Kintex-7 FPGA KC705 Evaluation Kit,the JTAG chain may not initializeon the KC705 in iMPACT(regardless of which FMC connector is used).

In ChipScope Analyzer, the JTAG chain may not initialize and the ILA may not trigger. How can this issue be resolved?


To resolve this issue, place a jumper on J5 headerpins 6-7 (FMC_TDO and FMC_TDI).

The XM105 Debug FMC card needs to shunt TDI-TDO via a jumper on the board.

The 7-Series boards use the FMC PRSNT_L signal when active (low) to open the analog switch, as the FMC spec states, to indicate that the mezzanine card is to take control of the JTAG nets.
