6.3. Nios® V Processor Example

The following is the example of running Ashling* GDBServer at port 54321 on Agilex™ 7 FPGA - Hello World Design on Nios® V/m Processor example design. 
$ jtagconfig.exe -d
1) AGF FPGA Development Kit on 10.107.209.7:3590 [3-1.1]
   (JTAG Server Version 22.1.0 Build 174 03/30/2022 SC Pro Edition)
  C341A0DD   AGFB014R24A(.|R1|R2)/.. (IR=10)
    Design hash    74DFB795DF11A555CEDF
    + Node 00486E00  Source/Probe #0
    + Node 08986E00  Nios V #0
    + Node 0C006E00  JTAG UART #0
  031830DD   10M16S(A|C|L) (IR=10)

  Captured DR after reset = (30D068376063061BB020D10DD) [98]
  Captured IR after reset = (006AAD55) [32]
  Captured Bypass after reset = (0A) [5]
  Captured Bypass chain = (00) [5]
  JTAG clock speed auto-adjustment is enabled. To disable, set JtagClockAutoAdjust parameter to 0
  JTAG clock speed 24 MHz

Refer to the following steps to debug the Nios® V processor application ELF in the GDB:

  1. On the first terminal or command prompt, start the Ashling* GDBServer. For the rest of the walkthrough, this terminal is called as Ashling* GDBServer.
    $ ash-riscv-gdb-server.exe --device C341A0DD \
--auto-detect true --probe-type usb-blaster-2 \
--core-number 0 --jtag-frequency auto-adjust \
--gdb-port 54321

Ashling GDB Server for RISC-V (ash-riscv-gdb-server).
v23.3.2, 01-Sep-2023, (c)Ashling Microsystems Ltd 2023.

Initializing connection ...
Checking for an active debug connection using the selected debug probe (SN: 16777217):

Waiting for debugger connection on port 54321 for core 0.
Press 'Q' to Quit.
  2. On another terminal or command prompt, start the GDB and connect to port 54321. For the rest of the walkthrough, this terminal is called as GBD.
    $ riscv32-unknown-elf-gdb.exe app_hal.elf
