As I understand it, ARM processors internal pull-ups are just not strong enough, so you need a set of pull-ups on the SCL/SDA lines. I.e., it is not a 'bug', but a 'feature'. I was looking through...
From your picture, it looks like the pull-up resistors are on the wrong pins (it looks like you have attached the resistors to pins 24, 25, an 26). They should be on the same pins as SDA/SCL. Even...
