Quartus Programmer fails to auto detect device on Cyclone10 GX Dev kit
Hello,
I am testing ASx4 configuration on Cyclone10 GX Dev kit. I use Quartus Programmer tool to download .jic file to flash. In Quartus: Tool -> Programmer GUI, when I click auto detect, it cannot detect the device correctly (see attached screenshot auto_detect_fail.png). Only Max10 is detected. Sometimes Quartus main message window gives one error message as below, sometimes no error message at all.
Error(209053): Unexpected error in JTAG server -- error code 4
Error(209053): Unexpected error in JTAG server -- error code 2
Error(209053): Unexpected error in JTAG server -- error code 7
When I execute the BoardTestSystem application (coming with Cyclone10 GX Dev Kit), it pops up an error message "FPGA is not detected in the Jtag Chain".
It was working well before. Both Max10 and Cyclone10 GX FPGA device could be auto detected successfully (see attached screenshot auto_detect_sucess.png). Recently it suddenly stops working. I was testing with Quartus 20.4. After having the problem, I also tested with Quartus 21.1. The results are the same.
What could be wrong? How can I fix it?
Thanks!
