Hello, I have the miniOVHD and installed the Mobiflight firmware 1.0.5, and when I try to test a miniOVHD project from flightsim.to, I get ConfigErrorException_SetCustomDevice. The run button doesn't work either. When I have a project for just the miniFCU and EFIS, everything works. But when I have a project for just the miniOVHD, or for the miniFCU/EFIS and OVHD, it doesn't work. The miniOVHD does display a yellow light. It seems like the miniOVHD isn't recognized. What am I doing wrong??? I use MobiFlight beta 10.5.3.20

Hi Neil, it's the same person I mentioned in my posting about it.

#

you have to upload the device config that is provided by miniCockpit

#

firmware is one thing

#

device config the second step

#

just use the button next to the"upload board's default config"
