D435i on Raspberry Pi 3b+, RuntimeError: Couldn't resolve requests

Hi,

I am using the Realsense D435i on a Raspberry Pi 3b+. Here's the specs:

OS: Raspberry Pi OS 2020-08-20-raspios-buster-armhf-lite

Realsense SDK: v2.39.0

Firmware 5.12.2.100

Serial Number: 937622071937

The D435i is connected on a USB2.0 port with a USB2.0 cable.

In my code, I create 2 pipelines, one for the images and one for the IMU, for asynchronous reading. The device can stream perfectly the following data:

- depth at 480 x 270, 6fps

- color at 640 x 480 at 6 fps

- gyro at 200Hz

- acceleration at 250Hz

I then acquired 4 new Realsense D435i cameras, and they give an error at runtime:

pipeline_IMU.start(config_IMU) RuntimeError: Couldn't resolve requests

Launching rs-enumerate-devices.exe it shows the depth sensor only, which is probably the problem.

I tried to update the firmware to a new version, but the problem was not solved. The serial number of one of the new devices is: 017322070770

Any suggestions?

Thank you,

Agostino

Some more thigs:

- the Raspberry Pi OS is headless, so I cannot see use the Realsense Viewer

- if I connect the D435i on a windows machine it shows correctly on the Realsense Viewer

Hi Agostino Gibaldi

Edit: As you have also posted this question on the RealSense GitHub forum, I will handle your case there. Thanks!
