Hi ashutoshsriram​ 

Can you try accessing the core using OpenOCD (niosv-download -o)?
The failing Ashling version (you had) is exactly the same v25.2.1 (version dated 9th May 2025) reported in the KDB.

Why does Ashling* RiscFree* IDE for Altera® FPGAs detect Core 0 only in a Nios® V processor multicore system? | Altera Community - 349124 

If the OpenOCD is able to select the different core, try downloading the standalone Ashling RiscFree IDE + Quartus Programmer in Quartus Standard 24.1 (Link).

  • The IDE is 25.1.1 (version dated 31st Jan 2025), which doesn't have this issue.
  • No new license is needed.

Since your Ashling version is v25.2.1, my guess is that you are using the Ashling IDE from Quartus Standard 25.1 installation package.

Thus, switch to a different Ashling version might help.

Regards,
Liang Yu

Hi ashutoshsriram 

 

Did upgrading the Ashling IDE Version resolves your issue?
