So, it seems you have a bus without a pull-up resistor (or a broken one?) but use now a push-pull design. This is against the I2C standard and for most circiuts quite dangerous as it can lead to shortcuts. Do you have any hints that the bus is designed this way? In which driver do you want to use the new flag? Thanks, Wolfram
