Stefan, I copied the userspace from Jonas' repo and reran the make process. The resulting run of my original or1ksim is shown below (it errors out and can’t open ‘/‘). So then I reran the make process with the original userspace, downloaded and installed the git HEAD version of or1ksim, and reran the simulator, and this time it worked. Now if I want to use a more recent version of mor1kx for the HW build as you suggested, how can I do that using the orpsocv2 file set? Or do I have to start over with orpsocv3?
