Barometer Read Error

When I run barometer example code it gives following error (attached screen shot) with pressure and temperature readings.I use emlid navio 20160408 newer os and I do not run APM flight stack. Anyone help please.

@Amila have you used screws to fix Navio2 to the Raspberry Pi?

@ mikhailavkhimenia Thanks for quick reply. Yes I used screws (Which is Provided by emlid) to fix to navio2 to raspbery pi.

Does that happen on both examples for barometer - C++ and Python?
Could you please provide a photo how everything is connected?
