ADIS16480 with Teensy3 SPI problems

Hello,

 

I've been trying for quite a few days to integrate an ADIS16480 from Analog Devices with the Teensy 3.0 without any result. No matter what I do, the IMU doesnt answer. In the past, I worked with an ADIS16488 and I had also a lot of problems for communication with other microprocessor. I know it  works because I can test it in another platform and it works perfectly.

 

Here there is a screen capture of the logic analyzer with the signals for the communications. To me, they seem perfect but still the IMU doesnt responds (with 0x4060 after the first 0x7E00).

Has anyone had this problem before? How it has been solved?

 

Any help would very much appreciated because I'm beginning to despair.

 

Thanks.
