[Lava-users] Help adding new device type

Hi everyone, I'm trying to add own device-type to my lab, but I'm facing some difficulties when running jobs. I have the following log error:

I clearly understand the log but I'm not able to figure out what to do: I thought it will be enough describing boot/power actions into device-type. But it seems not... Do I need to create a .conf file into /usr/lib/python2.7/dist-packages/lava_dispatcher/default-config/lava-dispatcher/device-types folder ?

By the way I'm not sure to understand the .conf purpose ? Are they here, only to be some default files ?

I attached my device-type and my job, maybe it will help you !

Thanks a lot ;)

P.S: I already did some jobs on Qemu and bbb and read the whole documentation.
