Pi 4

[plucker]

Does this run on a Pi 4? I can't seem to get it to work. FCSERVER seems to be crashing and if I go to the IP address of the Pi, I get the Glediator interface, not the FCSERVER one.

The Pi is continuously issuing this error:

02.12.20 20:40:39 (+0000) fcserver /usr/bin/entry.sh: line 59: /usr/src/app/fcserver-rpi: No such file or directory

And FCSERVER keep trying to restart and hitting the same problem

UPDATE: I tried on a Pi 3+ and have the same issue.

The instructions here: https://www.balena.io/blog/build-festive-lighting-for-the-holidays-with-balena/

don't show a VNC process running and say that if you connect to the ip of the pi you should get the fadecandy web interface.

Thanks for highlighting, it's definitely not been tested on a Pi 4 but it is currently working on the Pi 3 - I wonder if you used a 64-bit Pi 3 OS? That might cause the issue, but this is something I can look into.

The blog post you linked is the old version (note there's a link at the very top of the post saying it's been updated) - if you check that one out it may make a bit more sense. I made the note a bit bigger to hopefully make it stand out a bit more.

Thank you - I missed that note, and will try again with 64-bit OS on a Pi3 to see if that helps

Ah I was thinking that if you had used the 64-bit OS that might be a problem, I've only tested it on the 32-bit one so far - sorry for lack of clarity there. I wonder if there's anything in the build logs that indicate a problem as well (you can find these under releases in the dashboard). That file that's missing is downloaded on demand here: https://github.com/balenalabs-incubator/fadecandy-led-controller/blob/master/fcserver/Dockerfile.template#L6 but if that failed I'd expect the whole build to fail. Nevertheless I will try to grab some time to look at this as well.

@plucker if you download the latest changes and push again Pi 4 should now work, just tested with mine here :)

Oh magic, I'll give it a go, been a bit busy this week but probably get to it at the weekend
