Can't Debug Nios V on CL10 LP

Hello,

I am working on trying to implement a Nios V system on a CL10LP SOM from Aries Embedded. I have tried using the Nios V for Arria 10 tutorial as a guide in addition I examined the example with HyperRam from Aries themselves. Everything appears to build correctly and the .sof appears to program correctly, I can find no connection difference between what I have and them. The Nios V shows up on JTAG chain scans in RiscFree before I launch the debugger but it always fails saying it can't find the hart, which as far as I understand it is the running thread of the Nios V. I am running Quartus Standard Lite 23.1.

Is there a known common cause of this issue? It feels like I must have an issue with my BSP Settings and/or linker script but everything appears to match every reference I can find.

I really need to get this program moving and as a temporary solution I am looking at installing the 2017 toolchain so I can use the Nios II examples for the CL10 LP as the tutorials describe, at least that might get me to a functioning system so I can start working on figuring out the DMA aspect of my design. Though I anticipate this will make trying to utilize the HyperRAM more challenging as a consequence so not ideal either.

    Sorry I couldn't include everything information wise yesterday, the following shows more of my project.

    Here is my platform designer for the most stripped down test I am trying:

    Hi,

    What did you do when you encountered the debugger error?

    Can you share below information when you try to connect the kit where the sof has been programmed sucessfully?

    Thank you,

    Ann
