Unable to load Ashling Riscfree NiosV libraries

Hello,

I have been trying to make Ashling Riscfree for NiosV debugging work on our Linux system with Quartus v23.1;

I have installed RIscFree together with Quartus from the all-in-one data package.

Whenever I start RiscFree, Eclipse loads but I see none of the actual plugins for NiosV.


This is the .log I see in my workspace:

I have tried making a "clean" run of RiscFree, by using the following custom .sh:

 

#!/bin/bash

 

# --- Definizione Percorsi ---

# Usiamo il percorso che hai indicato tu nei messaggi precedenti

export QUARTUS_INSTALL_DIR=/opt/intelFPGA_pro/Quartus23.1

export QUARTUS_ROOTDIR=$QUARTUS_INSTALL_DIR/quartus

export NIOSV_HOME=$QUARTUS_INSTALL_DIR/niosv

 

# --- Configurazione Ambiente ---

# Aggiungiamo i binari di Quartus e Nios V al PATH

export PATH=$QUARTUS_ROOTDIR/bin:$NIOSV_HOME/bin:$PATH

 

# Variabili fondamentali per i plugin Ashling

export RISCV_JET_PATH=$NIOSV_HOME/bin

 

# --- Risoluzione problemi grafici MobaXterm/X11 ---

export NO_AT_BRIDGE=1

# Se l'interfaccia dovesse apparire vuota o nera, prova a cambiare 0 con 1 qui sotto

export SWT_GTK3=0

 

# --- Avvio IDE ---

echo "Inizializzazione ambiente Nios V e avvio RiscFree..."

cd $QUARTUS_INSTALL_DIR/riscfree/RiscFree/

./RiscFree -clean -data ~/workspace_niosv &

But this has changed absolutely nothing.

It is impossible to see NIOS V or Ashling RiscFree integration in the RiscFree environment.


What could be the issue?

I will now add a few infos about our system.

I am worried JAVA might be causing issues but I have not been able to solve them.

    Hi Cloudscraper​ 

    Whenever I start RiscFree, Eclipse loads but I see none of the actual plugins for NiosV.

    Can you specify what observation that leads to your hypothesis that Nios V plugin is not integrated?

    The Ashling RiscFree IDE is built-in with Nios V and HPS plugin once installed. You are not required to install custom extensions/plugins.

    Thus, it is unusual that Nios V plugin is missing in your RiscFree IDE.

    If I were to guess, I think:
    You were referring to the doc version 25.3.1, but it is RiscFree IDE v23.1 that is installed.
    As such, you are experiencing missing plugins like the "Import Nios V CMake Project" button. 
    In truth, the "Import Nios V CMake Project" button is yet to be introduced in RiscFree IDE v23.1, as documented in the doc version 23.1.

    Regards,
    Liang Yu

      Hello, so:

      there is nothing in my entire ashling riscfree window that refers to NiosV, not in new project wizard, not in import wizard, nowhere else. I will anyway double check on my server if the description explained in the manual you have just linked is realistic for our usecase.

        Hi Cloudscraper​ ,

        there is nothing in my entire ashling riscfree window that refers to NiosV

        I see, you are correct.
        I reviewed the RiscFree IDE v23.1, and the following are my observations.

         

        not in new project wizard

        Most Nios V projects are imported BSP & APP projects. Currently, there is no equivalent "File > New > Nios II Application and BSP from Template" in RiscFree IDE.

        not in import wizard

        In RiscFree IDE v23.1, the import wizard is based on "File > New > Project > C/C++ > C++ Project". So, there is no "Nios V" text throughout the whole flow. But there will be a dedicated import feature called Import Nios V CMake Project starting from RiscFree IDE v24.1.

        nowhere else

        Debugging side of things --- Nios V is using the RISC-V Hardware Debugging run/debug configuration option. So, another no "Nios V" text workflow.  

         

        I will anyway double check on my server if the description explained in the manual you have just linked is realistic for our usecase.

        Thanks for your help. I hope that my hypothesis is valid, and you will be unblocked soon. 

        If possible, please share your expected first impression. We and our partner, Ashling are interested to hear more to make the tool more intuitive. 

        Regards,
        Liang Yu
