PicoSoC demo does not work out of the box

[JamesTimothyMeech]

When I attempt to build the PicoSoC demo by running TARGET="arty_100" make -C picosoc_demo

it initially appears to build the example but then I get his error:

I am experiencing a similar issue. Seemingly the f4pga directory is not in the share folder.

picosoc demo is tested in CI and the last run is green: https://github.com/chipsalliance/f4pga-examples/actions/runs/5593603252/jobs/10227444844

Having said that it targets arty_35

Have you tried other targets or just arty_100?

figured it out: it was a pretty dumb issue with the installation. the

wasn't making the /share/f4pga directory. it had to be modified to
