VOXL2 Mini – Royale createDevice failed when starting ToF camera

[Piyush Singh]

Hi ModalAI team,

I am working with a VOXL2 Mini test fixture (TF-M0104) and encountering an issue when starting the ToF camera.

The voxl-camera-server starts successfully and all cameras initialize, but it crashes when the ToF bridge attempts to initialize the Royale device.

Additional details:

• Platform: VOXL2 Mini (TF-M0104)
• Camera server starts all 4 cameras
• The crash occurs right after the ToF bridge initialization.

Could you please advise what might cause Royale createDevice to fail in this situation?

I have attached a screenshot of the full terminal output for reference.

Thanks in advance for your help.

@Piyush-Singh ,

Which TOF sensor do you have plugged into VOXL2 Mini (there are two options) and what is the camera type listed for the TOF entry in voxl-camera-server.conf? there may be a mismatch..

Config file TOF options are :

• pmd-tof for the (EOL) TOF V1 : https://docs.modalai.com/M0040/
• pmd-tof-liow2 for the new TOF V2 : https://docs.modalai.com/M0169/ (https://docs.modalai.com/M0178/) - two different variants that differ in the connector type that connects them to VOXL2
