After flashing with the latest SDK, and configuring mpa, I received a message saying that server imu calibration files are missing. The imu server is not working either as seen below:

When I inspect services it shows that it is enabled but not running:

Can you please suggest a solution as I am unable to make this work even after re-flashing a few times. Thank you.

@Advait-Pandit Did you ever figure this out? We're running into the same problem on multiple VOXL 2s.

@czarsimon You may want to open your own thread, RB5 handles IMUs differently than VOXL 2 so the solution will likely be different
