    I2C extender connected on TAG4 startup


      Hi all,


      I am having problems starting the board when an I2C device is connected (GND, VCC and one or both of CLK and SDA) to J9. Even when I comment out all code that uses I2C and P2/P8 initialization, the board just won't start (on a coin cell battery) if external I2C is initially connected. Once started, I can connect the external I2C device no problem. Any ideas how to fix this?
