Hello Forum,I'm using: - Cyclone IV e3 - ALTERA USB Blaster Rev. C - Quartus Prime Lite When I hit Auto Detect in the Programmer, it says there is something wrong with the JTAG chain and takes me to the debugger. Next I hit "Test JTAG Chain" and the session log is attached. I can't understand what I'm doing wrong - I've checked the IDE cable and that seems fine. I've checked the power pins and they are correct. Please help. Session log: !Error: JTAG chain problem detected !Error: TDI connection to the first detected device UNKNOWN_FFFFFFFD might be shorted to GND !Error: The TCK and TMS connections to the device before the first detected device UNKNOWN_FFFFFFFD might have a problem !Info: Detected 2 device(s) !Info: Device 1: UNKNOWN_FFFFFFFD !Info: Device 2: 10CL006(Y|Z)/10CL010(Y|Z)/..
