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)/..
