No RGB on D435i

  Hi A Elghozi  Support for RealSense cameras is provided through forums such as this one, or at the RealSense GitHub forum.

  https://github.com/IntelRealSense/librealsense/issues 

  If you are able to obtain an RGB image at least one out of ten times then it suggests a software problem rather than a problem with the camera hardware. 

  If the firmware driver inside the camera does not detect the RGB component inside the D435i then it identifies the camera model as D430 (a model that does not have an RGB sensor) and so RGB would not be accessible on the camera.

  In the RealSense Viewer, is the camera name at the top of the Viewer side-panel stated as D430 when the RGB is not accessible, please?

  If the Viewer is detecting the camera as USB2 then it should say 2.1 beside the camera name at the top of the options side-panel instead of 3.1 or 3.2.

  It's detected as D435i by USB3.2

  When I enable the rgb sensor, sometimes the rgb is not showing, sometimes it does. Occasionally, when I switched on then off, it is impossible to enable again (rgb).

  Are there any error messages in the log panel at the bottom of the Viewer, please?

  Yes there are so many lol

  Error messages :

  Request: RGB8 Color,
  Resolved to: YUYV Color,

  Found 1 unreachable streams, 320 extrinsics deleted

  Backend in rs2_get_option(options:000001D388FE6D40, option:Backlight Compensation):

  Found 1 unreachable streams, 320 extrinsics deleted

   

  By the way, there is no rgb stream displayed on the calibration tool software (dynamic calibrator) when I launch the calibration process.

  Thanks, the error message was very helpful.  

  Considering the extent of the errors, I would next recommend trying to downgrade the firmware to the previous version and then re-upgrade to the current one.

  STEP ONE

  Visit the firmware file download page and download the firmware file Signed_Image_UVC_5_12_3_0.bin

  https://dev.intelrealsense.com/docs/firmware-releases 

  STEP TWO

  In the RealSense Viewer, go to the More option at the top of the Viewer's options side-panel and select the Update Firmware menu option.  Select the firmware file that you downloaded.

  STEP THREE

  Once the firmware 5.12.3 has successfully installed, check whether RGB now works with the 5.12.3 firmware version.

  STEP FOUR

  If you still want to use the latest firmware version, go back to More and select the option Install Recommend Firmware to re-upgrade to 5.12.5

  Thank you for the tutorial but it didn't solve the issue. I think I have more information about it. When I enable stereo module and others disabled, it's fine. Then I enable rgb and sometimes I have it. Then if I enable motion module, rgb disappears.

  

  You can see on the snapshot that I'm connected through USB 3.2 but I still have "no frames received" message. I was on 5.12.3 firmware.

  I always have these messages as you can see on the previous snapshot :

  Exception was thrown during user processing callback!
  null pointer passed for argument "frame"

  It may be related to a lack of system resources, with instability increasing as more streams are activated and placing a processing burden on the computer.  What computer / computing device are you using the camera with, please?

  I tested it on 3 different computers and I have the same issue. One is a laptop, one is a desktop and one is a war machine (i5 9600K, GTX 1080 Ti, 16Go RAM, SSD, ...). I don't think it is the cause of the issue. On all computers, the SSDs, CPUs and RAM were all under 33% load.

  Are you using with the camera the official short USB cable supplied with it, or are you using your own choice of cable that is longer, please?

  If you are experiencing the same issue on multiple computers, then it narrows the most likely options down to:

  -  A faulty USB cable that cannot cope with streaming high volumes of data

  -  Faulty firmware (unlikely, as you have downgraded and re-upgraded)

  - Bad calibration

   

  It may be worth performing a Gold Reset on the camera to reset it to its factory-new internal configuration.  This can be done with the following steps: 

  1.  Install the Dynamic Calibrator software for the 400 Series cameras.

  https://downloadcenter.intel.com/download/29618/Intel-RealSense-D400-Series-Dynamic-Calibration-Tool 

  This also installs a program called CustomRW.

  2.  In the CustomRW program, input the command below to initiate a Gold Reset to factory defaults: 

  Intel.RealSense.CustomRW -g

   

  BTW, what happens if you activate the RGB stream first and then the Stereo Module?   Do you still get a degradation in performance if you activate the streams in that order?

  Most of the time, it happens when I activate rgb after stereo. Thank you for the information.
