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.

    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,

Currently, I am not able to share the FPGA design directly. But, I have an update in Arria-10 board. I used to get the error

*****************************************************************
Initializing connection...
Cannot set the JTAG Frequency, continuing with auto adjust mode.
Error occured during enumeration of RISC-V harts(no hart found).

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

A few changes done in FPGA design. Currently, I am getting the error as

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

Error in services launch sequence
GDB prompt not read

and when I look at the console I see,

Initializing connection ...
Cannot set the JTAG frequency, continuing with auto adjust mode

Is there anything here that may help us to solve the problem? What I notice is that core gets in halted state. That may cause such an issue?

Thanks,

Balerion
