The cmake logic was changing behaviour depending on if `git` is installed or not. So in my sbuild run it was fine because it wasn't but if git is available it tries to run it and fails. I've submitted a fix upstream using the handy git export-subst trick I'm so fond of and would like to see more projects adopt: https://github.com/YosysHQ/prjtrellis/pull/227. > > nextpnr: > > > > - debian/upstream/metadata: Some of the authors have updated names that > > should be used instead of the old names.

I should learn to read, this is just the upstream metadata.

Or maybe upstream "make clean" needs to be fixed.

I have to copy these manually as they are not installed by upstream as they just embed the data into the executables Thanks, --Daniel

Yes, I have a board, and I can do testing if I don't forget about it. Feel free to ping me when the package is ready. Jonathan

I don't have an ECP5 devboard but what I have rediscovered recently is a Tang Nano 9k (Gowin GW1N) devboard. Hence I've been working on enabling gowin support. I've got project apicula and nextpnr packaged already but I'm waiting on a sponsor. In the meantime I'm having a look at prjtrellis too, but since I don't have any testing hardware I was wondering if you'd be able to do testing once I finish packaging? --Daniel
