I have a design that instantiates a Nios2 Gen2 core with JTAG debug enabled and a JTAG UART. These are connected properly as far as I can tell. The UART appears in the system.h file, and the fit report shows that the JTAG hardware was included for both. However, when I use "jtagconfig -n", only the FPGA shows up. Neither the Nios debug interface or UART show up as nodes in the FPGA design.
$ jtagconfig -n
1) USB-BlasterII [USB-1]
4BA00477 SOCVHPS
02D020DD 5CSEBA6(.|ES)/5CSEMA6/..
I cannot connect to Nios from Eclipse using the debugger and I cannot connect to the UART using nios2-terminal because they do not show up as nodes. I can, however download the sof using either the Quartus Programmer or nios2-configure-sof.
Am I supposed to somehow enable these JTAG features somewhere? Why don't they appear?
I am using the Cyclone V SoC Development Kit. Let me know if I need to provide more info.
Thanks,
Pete

Hi Pete,
Are you using the JTAG IP included into the Qsys design?
Can you please share with me the Qsys design you have for NIOS II?

Hi,
The .qsys looks ok. I am suspecting the system ID is not matching. Can you see the NIOS II processor via NIOS II SBT? it may give you an error showing that there is a mismatch in the system ID and there you can ignore it by checking the box of ignore system ID.
Can you please check this?
