gdb-server can't find Cyclone II board

Running 'jtagconfig', from an EDS command shell should provide you with the necessary information. You should see output similar to the following:

1) USB-Blaster 
  020010DD   EP1S10
    Node 11104600
    Node 0C006E00

The two "nodes" are (in my case) the jtag_uart in my design and the jtag debug core, which is used to communicate with the gdb server....

Here are a couple of pointers:

1. jtagd doesn't need to be started as a separate process. The act of starting any of the "clients" that use jtagd (i.e.: jtagconfig or gdb_server) should be enough.

2. Don't call the gdb-server-wrapped command, directly.

- Though I don't think you're doing this, I wanted to be sure.

Here's the sort of command sequence, that I've used successfully:

1.  Start the gdb server:  nios2-gdb-server --tcpport=2342 --tcppersist
2.  Start the client:  nios2-elf-gdb <your_program>.elf
3.  From within the client&#39;s GDB console:
(gdb) target remote localhost:2342
Remote debugging using localhost:2342
(gdb) load

Start address 0x1000000, load size 184832
Transfer rate: 739328 bits/sec, 510 bytes/write.

From this point, you should be able to start, step and debug your code. In other words, it's standard GDB stuff....once you have the conduit setup.
