I2C startup probelm

  • Hi,

    I have a gpy and a pytrack (v1) connected to a sparkfun Qwiic TMP117 board over I2C through the external IO of the pytrack like this:

    pytrack external IO TMP117
    3V3_SENSORS 3.3V
    P10 SCL
    P11 SDA

    Unfortunately when the TMP117 board is connected, the gpy/pytrack won't boot when it gets hooked up to a power source. I have to press the reset button on the gpy for it to boot.

    Any idea why is this happening and how could I solve this?

    P.S. I also try switching P9 to SDA and P11 to INT, same result.
