Hi, I'm trying to get the Hello World Nios II example to run on an Cyclone 10 GX. The design build and the sof-programming run without a problem. But the Nios II Eclipse can't find the Nios as targe...

Based on this documentation, a jtagconfig -n should output something like

$ jtagconfig -n
1) 
               Intel® FPGA Download Cable [USB-0]
020050DD EP1S40/_HARDCOPY_FPGA_PROTOTYPE
Node 11104600
Node 0C006E00

But mine outputs no nodes:

could this be the reason? And how to solve this?

    Hi,

    I'm having the same issue with my Cyclone 10 FPGA on Ubuntu 20.04 and tried everything @AnandRaj_S_Intel suggested. I also tried running the nios2_command_shell script and then ran 'nios2-terminal', which couldn't run due to the lack of detected devices. But when I run jtagconfig, I can see my blaster connected and also the Cyclone under it, just like the snippet above.

    Cheers

      Hi anonimcs,

      Can you share the error log output when you run nios2-terminal command? I suspect the Nios II processor isn’t present in the loaded .sof, or its debug interface isn’t correctly configured.

      Thanks,
