Nios-V .elf download failure

Hi all, I am trying to download two simple Nios-V apps using RiscFree IDE to my target boards. One of my board has Cyclone-V and the other has Arria-10. My main.cpp files are same but their BSPs are...

    Hi Balerion,

    When you are able to download the elf using the --go command, it is likely that your setup on the board is correct already

    There is an update by the way. I tried the command

    *****************************************************************
    "niosv-download.exe app.elf --go"

    -> Hello Nios V World!

    *****************************************************************

    And you saw this error when trying to connect with RiscFree

    Initializing connection ...
    Cannot set the JTAG frequency, continuing with auto adjust mode
    Connected to target device with IDCODE 0x2e240dd using USB-Blaster-2 (1) via JTAG at 24.00MHz.

    Waiting for debugger connection on port 56767.
    Press 'Q' to Quit.

    This could be your RiscFree's setting or your host system's setting not set correctly.

    Likely Root Causes
    GDB Server launched by risc free failes to connect IDE cannot detect the prompt (gdb) migh due to the following

    a) Firewall/antivrus is blocking the local host port access

    b) IDE times out before connection is established

    c) There is a mismatch in how the debug config launches

    Possible Fix

    a) Temporarily disable antivirus / firewall

    b) Try launch RiscFree as administrator

    c) Increase debugger timeout (if IDE allows)

    Please let me know the result after you try the step and provide screenshot if possible.

    Regards,

Hi,

What version that you use for the RiscFree? When you debug using RiscFree, did you configure the debug configuration first to connect to the board JTAG?

Boon Khai.

    Hi,

    I am using RiscFree IDE v24.3.1, 9th Aug 2024. For debugging I first configure debug configuration then click apply then click debug. That is what I'm doing. By the way, I observed something which is when I run "niosv-download.exe app.elf --go" I see TCP packet traffic in localhost:port(at which gdb server waits for client to connect). However, when I try to do same over RiscFree IDE. I don't see any packets. This may be sign of what the problem is?

    Thanks,

    Balerion

      Hi Balerion,

      The RiscFree version looks fine, can you help to screen shot your RiscFree IDE's debug configuration? Wonder if you selected the correct board at the debug configuration setting?
