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
