I have a MSO754 with the I2C serial decode option installed. I have it set up to trigger on a start condition. It triggers at a random point and does not parse the data correctly. Data displayed is garbage, ACKs are not recognized etc. I can scroll through the trace and it looks ok, also this data is being received and parsed correctly by the connected nodes. Other than assigning the clock and data channels and number of bits in the address there's not a lot of things to adjust in I2C so not sure what to do.
