ADIS16460 IMU's with Raspberry Pi

Hello everyone,

I am trying connecting my ADIS16460 (EVAL-ADISIMU1) to a Raspberrypi 4 (using the ). I had been following the instruction on this guide:

1.  Load my SD Card with ADI Kuiper Linux image to Raspberry pi  (wiki.analog.com/.../release_notes)

 https://wiki.analog.com/resources/tools-software/linux-software/embedded_arm_images?redirect=1

and this video:

Using ADI IMU's with Raspberry Pi and MATLAB - YouTube    (2:05 min)

2. I configure my Raspberry pi with overlay in boot/config.txt  (dtoverlay=adis16460)

However when I verify  that the drivers loaded properly, I obtained an error:
