MIPI error after upgrading FW

Hi,

We encounter "Right MIPI error" and "Left MIPI error" sometimes captured by a callback similar to https://github.com/IntelRealSense/realsense-ros/blob/4.0.4/realsense2_camera/src/ros_sensor.cpp#L6-L24

after launching D435i from our c++ node quite similar to ROS node https://github.com/IntelRealSense/realsense-ros on Ubuntu18.04.

After catching the error, it HW seems to recover even without hard wareresetting and start stream the camera frames.

This error started to happen after we upgraded realsense SDK and FW as

SDK:

2.38.1-0 --> 2.50.0-0

FW

05.12.7.100 --> 05.13.0.50

Have there been any changes causing MIPI error more often by upgrading FW or SDK?

Hi Kota Mogami

Reports of MIPI errors occurring are highly rare (with left MIPI errors even rarer than right ones) and so there is insufficient data to establish a pattern regarding whether their occurrence tends to coincide with firmware or SDK version changes.

In your particular case, it sounds as though it is a non-serious momentary hiccup in communication with the camera hardware that immediately corrects itself and so is not a cause for concern.

Hi MartyG,

I understand. In our case, the issue started to appear on multiple devices we have after updating the SDK and FW, but we don't have more information either.

I would appreciate it if you update the cause on MIPI error in the future after you have found out the root cause of the issue.

MIPI errors typically do not provide clues about their root cause and are therefore like an unspecific "something went wrong" message.
