Gateway IMST IC880A / RBPI

Hi all
I just received my iC880A-SPI board on Friday and connected to a Raspberry PI. Installed the Gateway
software like this https://github.com/ttn-zh/ic880a-gateway/wiki (Thanks to gonzalocasas, good work). Unfortunately when starting the gateway software “sudo ./start.sh” I get this error:

ERROR:Version of calibration firmware not expected, actual:226 expected:2
ERROR:[main] failed to start the concentrator

The SPI connection seems ok. I compiled the library with debug and get lots of “SPI write success”.
Any ideas? The ic880 board is very new “Date 03/16” maybe the changed firmware?

Thanks
Werner
