Here is my FPGA schematic and some screenshots of the programmer software. This is running on Windows 10. When I try to access the chip, the blue light on the USB Blaster goes on for about half a second, and then I get "(Failed)" or "Unable to scan device chain." What am I doing wrong?

Hi,
- Connect JTAG pins correctly to the download cable header. Ensure the pin order is not reversed.
- Check if the board is Power properly. Check POR from the Handbook.
- Noise on any of JTAG pins could cause JTAG programming to fail for the entire chain.
- Auto-detect and check once.

Hi,
Check If another board working with the same setup(board, configuration, USB cable & power supply setup)? if yes.
We have to suspect board.
Check if the board is Power properly. Check POR from the Handbook
Check the pull-up resistors on the configuration side.
check for Solder Bridging, Lifted Components & Solder Skips.
Regards
Anand
