ADXL357 reads 0 on all axes?

Hello,

 

I am trying to use the ADXL357 with a TI TMS320F28069M processor. My problem is that when I read the accel data over SPI, all values are zero. When I initialize the accel, I first write to register 0x28 to set filter values and then write to register 0x2D to put the accel into measurement mode. I have tried using the reset register to cycle the device with mixed results. Does anyone have ideas for how to troubleshoot this device? It seems like it never makes it into measurement mode.

 

Thanks!
