Re: [ArduPilot on Voxl2](/topic/3640/ardupilot-on-voxl2)

Hey there! I've been trying to get ArduPilot running on a Starling 1 drone, and walked through the setup as outlined in the docs. I'm using ArduCopter v4.7.0, installed using the .deb file on ArduPilot's firmware page, but haven't been able to resolve the following SLPI error. I was hoping for a bit of guidance as to what would be causing this issue? I tried running with various .config files and had no such luck. Thanks! 

```
Couldn't locate SUID for slpi-link
Failed to detect SLPI LINK endpoint
slpi_link_init error -1 No such file or directory, retrying
```
