i2cdetect not detecting SparkFun LSM9DS1 IMU breakout board

HenryHenry New Member Posts: 1
Does anyone have experience using i2c with the upboard? Specifically, I am trying to use i2c to take measurements from the SparkFun LSM9DS1 IMU breakout board (https://www.sparkfun.com/products/13284). I have SDA connected to Up-Board pin 3, SCL connected to Up-Board pin 5, VDD connected to Up-Board pin 1, and GND connected to Up-Board pin 6 (see attached photo of the connections) . I am fairly sure these physical connections are correct, so I figure the problem must be somewhere in my linux configuration. I'm running Ubuntu 16.04 with the linux upboard kernel (https://launchpad.net/~ubilinux/+archive/ubuntu/up).

When I run: i2cdetect -y 1

from the linux command line, I get the output:

Error: Can't use SMBus Quick Write command on this bus

I have successfully used other IO functions on the 40 pin GPIO header, it's just i2c that isn't working. Any help or advice would be greatly appreciated!

    Try this slight variation of that command:
    i2cdetect -r -y 1

    Warning I have not tried it...

    But wonder if the 10k PU resistors on this board are sufficient? Can not see your jumpers, when this message loads on my machine about 90% of your images show up as gray, only the far left edges show up?
