    Hi ove 

     

     

    I managed to reproduce the issue on my end.

    It seems like this is a valid issue on the driver side to cause the error you are facing.

     

    A workaround currently is to limit the naming of the SystemID IP to "sysid".

     

     

    Could you possible to try that and see if it solves the issue?

I already did, but still compiles with "Unknown reference to alt_avalon_sysid_qsys_test"

Hi ove 

 

Is it possible that you could attached a full log of the command used?

I tried the steps on the environment here but could not see the error you are facing.

    Hi ove,

    You have to establish an Ashling RiscFree project which uses the CMake flow.

    https://docs.altera.com/r/docs/726952/25.3.1/nios-v-embedded-processor-design-handbook/building-the-application-projects

    Command line flow:

    cmake -G "Unix Makefiles" -B software/app/build -S software/app

    make -C software/app/build

    Or, you can do it in the RiscFree IDE by creating a C/C++ project, selecting CMake empty file flow and pointing to the software/app folder which contains the source file.
