Hi there,
just wanted to leave one finding here because I fiddeled around the whole day trying to get my Razberry GPIO DaughterCard on a brand new Raspbian Jessy Image to run:
This was my error message:
OFFLINE (COMMUNICATION_ERROR): Serial Error: Port /dev/ttyAMA0 does not exist
Additionally to the steps mentioned in
http://docs.openhab.org/installation/linux.html#privileges-for-common-peripherals
I had to edit
/boot/cmdline.txt
from
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait
to
dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait
leaving out the first console=serial0,115200
Hope this helps someone!
Cheers!
