Single_chan_pkt_fwd.service: status=210/CHROOT

[oberon]

Hello,

After the make install I get the following error:

● single_chan_pkt_fwd.service - Lora Packet Forwarder
Loaded: loaded (/lib/systemd/system/single_chan_pkt_fwd.service; enabled; vendor preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Thu 2018-06-07 20:31:22 CEST; 120ms ago

Makefile:23: recept voor doel 'install' is mislukt
make: *** [install] Fout 3

I can start ./single_chan_pkt_fwd without any problem. I just can't load it as as service.
I'm using an Raspberry Pi 3B.

Any idea what I'm doing wrong?

Thnx!
