7 years agoUnless there was a stale jtagd process left over when you were running as user jfrye.
To rule out this you could trysudo killall -9 jtagd
sudo /home/jfrye/Quartus/quartus/bin/jtagconfig
If that does not detect anything it might be related to the FTDI driver. Perhaps somebody with a Ubuntu 16.04 system have some input...
