STM3220g no I2C Pullups?

Question asked by h.brad on Jun 1, 2015
Recently designed a custom board based on the STM3220g eval board and notices the I2C lines looked very bad (long rise times). The internal pullups were enabled but the lines look nothing like the I2C on the evaluation board.

The only thing on the I2C bus on our custom board is the F207 and a micron image sensor.

Is there something I am missing? I know the internal pullups are too weak for I2C.
