librealsense: Calibration Failed. OCC ALL calibration cannot work with this camera!

Dear RealSense Team,

I am using Intel RealSense Viewer v2.44.0 application to do On-Chip Calibration (OCC) on a D415 camera.

---

Required Info
Camera Model	D415
Firmware Version	05.12.12.100
Operating System & Version	Ubuntu 18.04.6 LTS
Kernel Version (Linux Only)	5.4.0-86-generic
Platform	PC

Language	None
Segment	Robot

Issue Description

While doing OCC, the Intel RealSense Viewer shows following error:

Calibration Failed. OCC ALL calibration cannot work with this camera!

The following error was reported in the dialogue box. This dialog box appears after clicking on the “expand” label while OCC is going on.

Started On-Chip Calibration process
Starting one button calibration
Calibration failed with exception

ERROR: UNKNOWN in rs2_run_on_chip_calibration_cpp(device:0x55a4f7f4d2a0):

ERROR: UNKNOWN in rs2_run_on_chip_calibration_cpp(device:0x55a4f7f4d2a0):

I found following doubtful lines in the librealsense.log file:

Please see the attached screenshot for better understanding.

I tried following things but no success:

• Switching fast/slow/white wall procedure
• Placed camera 30 cm, 60cm, and 1m far from a white wall
• Used another D415 camera
• Used another USB3 cable
• Restarted the realsense-viewer
• Restarted the PC as well

I tried various things as listed above but the error “Calibration Failed. OCC ALL calibration cannot work with this camera!” still appears.
