KCU1250 Board Features and Operation
The JTAG chain of the KCU1250 board is shown in
. By default, only the UltraScale
FPGA is part of the chain (J6 jumper uninstalled). Installing the J6 jumper enables an 8-bit
bus transceiver (U69, SN74AVC8T245) and adds the FMC interfaces to the chain.
PROGRAM Pushbutton
Pressing the PROGRAM pushbutton SW7 (callout 14,
) asserts the active-Low
program pin of the FPGA.
