Hi! @Alex-Kushleyev 

When I run ```voxl-camera-server``` v2.2.17 following all the instructions for the EIS tech docs, I'm seeing the server crash. All the camera pipes are initialized, and the camera server starts with no problems, but when I either try to open the stream or attempt ```voxl-inspect-cam-ascii hires_misp_grey``` the camera server aborts. I'm using an imx412 sensor. Here are the error messages I see when I run the server in debug mode and then attempt to open the stream in voxl-portal:

Let me know if you have any advice on how to resolve this, thanks!

@SKA , I am not sure. please disable all streams except preview and try again. specifically disable:
- small_video
- large_video
- snapshot

Double check to make sure:
en_raw_preview: true
en_preview: true
en_misp : true

It seems you have at least small_video enabled.

What camera resolution are you requesting? (preview_width, preview_height)
