    FMC-CE Breaks JTAG Chain

    sdm posted a question in FPGA

    I've got the FMC-CE board plugged into a ZC706, and when I try to load open the Hardware Manager in Vivado, it finds my HW target, but there are no devices found. After a little digging I found that there is an FMC design rule that if you don't use the JTAG chain you need to tie the FMC TDI pin to the TDO pin. Looking at the schematic, this isn't done on the FMC-CE board. Both of these FMC pins (D30, D31) are disconnected. What's the best way to work around this to enable JTAG debug when this board is installed?
