How to get LSM9DS0 i2c to work?

I'm having trouble getting i2c communications working with LSM9DS0 iNEMO inertial module. I've wired it up, but it isn't responding to who_am_i read request. I've wired SDO to 1, so am using your default i2c address 0x3A, but I'm getting no slave ACK signals. Out of desperation wondering if I had the address wrong I pinged every i2c address, and still found no response. I've tried 100 kHz and 400 kHz, same result. I've also wired different i2c sensors, and they work fine, so I know the rest of my board works. Are there any tricks getting i2c to work?

Me too have the same problem gyro is working but accelerometer is not working, is there any way to check whether it is a hardware problem or software problem or soldering problem

Hello,

I have same problem :( I have

LSM9DS0 and LPS25H on the same I2C bus, but only LPS25H responds. I don't believe it's a soldering problem because i have made two boards to specially rule out random component and soldering faults. Also i've inspected them under microscope.

Anybody have some idea?

It still was a soldering problem on both boards... :S
