I2C Setup

[wonko]

Hmmm...maybe check your wiring?
I didn't compile the kernel, just updated to longsleep's latest.
I just hooked up several I2C devices on a custom board to the PI2 bus, and i2cdetect -y 1 worked just fine for me.

Fair enough - I'll try that out when I get back to the house.

Don't forget to have 4K7 PullUps on the I2C Bus !

Looking at the Pine schematic, those pullups are already there.
I made a custom board for my I2C devices, and put a place for the pullups, but didn't need to populate them.

You're right !
I didn't noticed those pullups before, and I have tendency to always provide some since many boards don't have them ...
