Hi,
If the switch is set correctly then you should always observed the Cyclone 10 in the JTAG chain. May I know if you have another PC to test it out?
Are you able to auto-detect anything on your JTAG? Or you are always seeing JTAG server error?

Hi John,
Yes, I tested with another PC. I also re-installed Quartus and USB-Blaster II device driver. The result is the same.
The auto detect can find MAX10 (10M08SA), as shown in the screenshot "auto_detect_fail.png" I attached earlier. The expect result should be as the screenshot "auto_detect_success.png" - MAX10 with 2*CFI_1Gb flash associated, and also Cyclone10 GX (10CX220Y).
I tested the JTAG chain with Quartus JTAG chain debugger. It says "JTAG chain connection is good. Detected 1 device(s)". Please see the attached screenshot "JTAG_chain_debugger.png".
The JTAG server errors I posted earlier do not always come out. No matter if there is JTAG server error, the auto detect result is the same, i.e., only 1 device (MAX10) is detected. While in the success case, 2 devices are expected.
Since it was working well and stopped working suddenly after I tested with an erase operation in Quartus Programmer tool. I suspect I accidently erased something, e.g., the contents in MAX10?
There is a simple instruction (included in Cyclone10 GX Dev Kit collaterals) on how to recover the board to factory default. I also attach the file here. However it is too simple. Can you please guide me how to do it. Especially the 2nd step - "program MAX10 via Quartus Programmer" and which file I need to program into MAX10?
Thanks!
