Over the weekend (1/28/17) I upgraded from Raspian and Openhab2 Snapshot to Openhabian and the first release of Openhab2.
Unfortunately, when I booted into Openhabian, I can’t seem to get the I2C bus to work correctly. I have followed the standard config of installing i2c-tools and making sure nothing is blacklisted. I ran Raspi-config to enable I2C on the device. I even tried giving the user Openhab complete authority in the Sudoers file.
However, when I run i2cdetect, I have no ID being sent back from the 23017 chip. The voltages all look good on the chip but it doesn’t seem to want to respond.
Is there something that has been removed from the original Raspian that would cripple the I2C bus?
