I am running into a couple of problems that I cant figure out.
Using the board discovery option only works when I run PNCconf as root. If I do not run as root, it will generate an error and under the output tab say "You need root privileges (or setuid root) to access PCI Hardware".
Is this normal or is this an install problem on my end?
When I run PNCConf as root, the board discovery option works fine and detects the board as it should. While running as root works to fix that, it causes other more major problems down the line. (For example, the /linuxcnc/configs and /linuxcnc/nc_files both are created as root folders, and linux cnc cant access them. It may also screw up some other things, but I am not sure on that)
Using the hostmot2 text method works fine and does not require you to run pncconf as root.
Both methods leave me with the same result. I think what is happening is it is looking a file that it cant find?
Sample one. Errors pulled from terminal while trying to run the PID Test through PNCconf

Any thoughts? I am not sure where to start on it.
If it tells you anything, I get the same error on a virtual machine. From what I can tell the setups for standardized mesa firmware work fine, so I think it is a problem isolated to the non standard mesa firmware.
Thanks,
Shawn
