Ethernet blaster cyclone V

Well, the blaster is working better Today, it almost worked till the end prog (failed on CONF_DONE pin check).

After that the ethernet blaster cannot be connected anymore, so it seems ethernet side is un-stable.

If I disconnect the ethernet cable and connect it back, still not found (connecting).

If I close Quartus programmer and re-detect the ethernet blaster, same issue.

If I power cycle the ethernet blaster (and keep Quartus open and the ethernet cable in),

then it works.

Seems like the ethernet blaster crashes.

LED is purple when it crashes at the config done check time.
