However, that didn't change anything regarding the download
speed. And I've tried setting the cable frequency manually
and several other options, but nothing helps. It still takes
too much time. Could the problem be with the cable driver?
Quite possibly it's a problem with the cable driver. Typically, if the
MDM / FSL download isn't working, then it completely fails to work (ie
takes zero time, but writes nothing if you get the FSL channel reset
poliarity wrong, or stalls forever if you don't hook up the clock).
The fact that the download is working, but taking forever, suggests a
host driver issue.
Does JTAG bitstream download take a sensible amount of time, or is it
also slower than you might expect?
The bitstream download takes 37 seconds.
Sounds pretty slow, unless it's an enormous FPGA (several V4FX100 in a
I'd be looking at the host drivers.
