Hi,
I used to be able to connect to my Altera Cyclone SBC using the following JLink Commander command using V6.20:
"C:\Program Files (x86)\SEGGER\JLink\JLink.exe" -device "CYCLONE V" -if JTAG -speed 4000 -AutoConnect 1 -JTAGConf -1,-1
Command output for 6.20i:

Any clue on why the Altera Cyclone V is not recognized anymore ? Thanks.
