Low-to-high transition on nCONFIG reconfigures the FPGA. Pin connection guidelines says to connect 10K pull up or leave unconnected on nCONFIG pin for Arria V FPGA. If it so, how does it reconfigure without low-to-high transition?
If you does not use nCONFIG pin to reconfigure Arria V FPGA, you can power cycle the board to reconfigure Arria V device.
Once you power OFF & ON the board, nCONFIG will trasition Low-to-High again.
