I'm encountering a weird issue when trying to program my Cyclone V GT FPGA Development Board.
I have generated my .sof file, and I am attempting to upload it. The programmer identifies the FPGA and quickly gets to 44-45% progress, hangs for 5-10 seconds, and then gives the error shown below:
I have other .sof files that I am able to program the board with - this is the only file where the error occurs. While this design is larger than things I have previously uploaded, it only takes up ~40% of device resources, so I don't see that this should be an issue.
Any and all recommendations are gladly accepted. Thank you!

It could just be a bad file. Maybe you can just rerun the Assembler and generate a new file. If it still doesn't work, I'd try a full recompile.
