More infos
after reading a bit and seeing where to look I may have found the error msg.
root@beaglebone:/home/debian# dmesg | grep i2c

4802a000.i2c seems to be I2C1
aliases {
i2c0 = "/ocp/i2c@44e0b000";
i2c1 = "/ocp/i2c@4802a000";
i2c2 = "/ocp/i2c@4819c000";
so it seems there may be a pinmux issue ?
this is on a stock image free standing BBG
I am a hardware dude. Whats all this software stuff anyhow? ;)
