Lubuntu - i2c devices gone on Orange Pi Lite

jespera · Published in 2016-7-12 14:43:49

Following the install of the official Lubuntu for Orange Pi Lite, I tried to hook up a MPU6050 mems gyro/accel to the i2c bus.
Unfortunately it seems that I have no i2c devices :-(

My python code (smbus based) does neither see any i2c devices and i2cdetect -y 0 or 1 or 2 says

Could not open file `/dev/i2c-1' or `/dev/i2c/1': No such file or directory

Do I need to enable some driver or not blacklist a module?? Is i2c even supported?
