Hi SYiwe,
I assume this “device unknown” issue due to Quartus Prime compatibility problem.
May I know which Quartus version you are using?
Maybe you can try program using the latest Quartus version to solve this issue.
Let me know if this workaround does not improve your issue.
Thanks. 😉

Thanks, MShafiq.
My quartus version is 17.0 currently, I think this version is compatible with Intel Arria 10 SoC.
I will try your method and send you the response ASAP.
I measured the voltage of TDI pin, the value is 1.775V, and VCCPGM is 1.8V, why the programmer remainds me TDI connection might be shorted to GND?
TDI pin is pulled up to VCCPGM following the instruction in pin connection guidelines. The impedance measured between TDI and GND is 1.029KΩ.
Here's the result of test JTAG chain:
Thanks, regards.

Besides, when I try JTAG chain debugging, the programmer reminds me "Incorrect clock value".
