We read the following section,
and this section,
but we are not sure what's the correct switch setting if we use external Blaster II download cable to program FPGA.
We connected external USB Blaster II to JTAG port, and tried all the switch combination exhaustively.
Quartus Programmer only detected FPGA successfully with three combinations:
Which one is expected switch setting?
Could you explain the definition of each switch more?
And let me make sure I have it right.
Does the default setting mean that we need to external download cable (i.e. connect computer and FPGA board by a Blaster II cable) ?
