bmp085 with uext interface beaglebone black

[Jay Kothari]

Hello,
     I am using mod-bmp085 with uext interface. I am interfaceing with beaglebone black. Following are my connection to beaglebone black

1)vcc(pin3)
2)gnd(pin1)
3)scl(pin17)(internally pulled up)
4)sda(pin18)(internally pulled up)

    But my BBB is not getting power due to this interface!!!!when I remove this interface it starts normally.Any idea why it is causing this problem. Do I need to attched external pull up resister to BBB

I2C1 is used to check for capes so why not use I2C2 instead? It states on this website that it is free.

By the way, both I2C1 and I2C2 don't appear to have pullups on the bus on the BBB so you may need them on your BMP085 board.
