Hi,
I know this question may be asked on Arduino Forum but it could be that someone on elment14 have tried Arduino Vidor 400 and proramed it using the instructions provided on getting started guide for Vidor 4000
https://docs.arduino.cc/tutorials/mkr-vidor-4000/vidor-gsvhdl/
The issue here is that I need more information on the tool used to flash the board. I have compiled the FPGA sample program on Quartus IDE and now want to upload the converted file using the tool mentioned for flashing the board.
