Stuck on Built With Nerves splash screen for example project

[cburman01]

Followed the instructions from the Example folder and am getting the Build With Nerves splash screen on an RPI3.

Tried:
I have re-burned the SD card numerous times.
verified network connection and the KIOSK_URL.

Any ideas?

Also wanted to add:

I've tried manually specifying the Display child in the app supervisor to rule out any config issues:

[
{WebengineKiosk, {[homepage: "http://192.168.1.2:4200", background: "black"], name: Display}}
]

This is usually due to another issue in your project. Unfortunately the easiest way to debug this is using a console cable. Would you be able to connect one?

[cburman01]

Thanks, I just ordered one and will report back once I get the output.

I've gone through and applied some upstream updates to the project, and also updated the example project to work with Elixir 1.8. I've tested booting it and it seems to be working. Once the 1.5.0 release is out, you should be able to test this again.

Here is the progress of the build:

So i am getting this when I do a deps.get from the Example folder:

Resolving kiosk_system_rpi3

     Status 404 Not Found
  => no_result

I also tried swapping out the kiosk_system_rpi3 dep to this: {:kiosk_system_rpi3, "~> 1.5", runtime: false, targets: :rpi3} but that release hasn't been published to hex yet.

Any idea why {:kiosk_system_rpi3, path: "../", runtime: false, targets: :rpi3} this would be looking for a release that doesn't exist? It's odd because I would assume the dependency would get compiled from that path instead of reaching out to git.

I checked the build progress and it appears to be finished.

[mobileoverlord]

Sorry bout that, I didn't notice it was done and just published the release.

[cburman01]

I was over zealous haha.

Ok I am still seeing the same issue. It appears mix is trying to locate the release with the wrong hash:

This is the correct url: https://github.com/LeToteTeam/kiosk_system_rpi3/releases/download/v1.5.0/kiosk_system_rpi3-portable-1.5.0-20F4A7D.tar.gz

This is the url hex is trying to pull: https://github.com/letoteteam/kiosk_system_rpi3/releases/download/v1.5.0/kiosk_system_rpi3-portable-1.5.0-5A3D0275E5BEA4D23DD3F8BF3EF5A131F4CA5F9AB1DD61259B04757F158F71DA.tar.gz

[mobileoverlord]

Do you have any local file modifications in your git repo? The hash is computed off the contents of the files listed in https://github.com/LeToteTeam/kiosk_system_rpi3/blob/master/mix.exs#L85-L106

I tested locally and it seems to have pulled the right file.

[cburman01]

Not that I see. Here is the output of my git status

example git:(master) git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean

[mobileoverlord]

Can you try running mix deps.get from the top level, then cd into the example folder ad run again? Curious why its computing a different hash.

[cburman01]

Interesting, I still get the same error when I deps.get in the root dir:

[cburman01]

What OS are you running on @mobileoverlord? I am wondering if different line endings are causing the hash to be calculated differently.. This is only a theory.

I'm on macOS Mojave 10.14.4

How do you customize one of those files? I was trying to go down the customization road and ran in to this.
