hires camera not detected

[Piyush Singh]

Hii Modalai Team,
Please help me , hires camera is not detected by camera server. I have connected hires to J6 L (using M0084) and Tracking to J7 L(M0135) .Camera server detects only tracking camera but not hires.

@Piyush-Singh, please double check that you have the imx214 sensormodule bin for slot 0 in /usr/lib/camera/ (since you have M0084 connected to J6 and the IMX214 camera connected to the "lower" port (JL) of M0084, so the resulting connection of the IMX214 camera will be mapped to VOXL2's J6L (slot 0)).

You can find all the sensormodule files in /usr/share/modalai/chi-cdk/

Hii, Please take a look:

Hi @Piyush-Singh,

Sorry for the delay. I believe your issue is the same as in this post : https://forum.modalai.com/topic/4975/hardware-configuration-for-2-m0014-tracking-1-m0169-pmd-tof-1-m0024-hires/ . Specifically, the kernel variant that is installed is 2.0.2 which is designed for newer camera adapters like M0188, M0195.

Please change your kernel to the 2.0.0 variant as described in the thread above (you can test it first before overwriting).

It looks like you do have the right sensormodules in place.

@Alex-Kushleyev Thanks for the reply.
I tested the HiRes camera with the 2.0.0 kernel variant as suggested. With this version, the HiRes camera is detected correctly, so that part seems to work as expected. However, I’m observing that the system temperature rises very quickly and crosses 80 °C+ during operation.

@Piyush-Singh

That’s good news. As for overheating, can you describe what tests you are running that use camera streams and what resolution?

[Piyush Singh]

@Alex-Kushleyev ,Thanks for the response.

For testing, I am running multiple camera streams simultaneously and go to web portal to see the streaming:

HiRes (IMX214): 30 FPS

Small video: 1024×768 (H.265)

Large video: 4208×3120 (H.265)

Snapshots enabled

PMD ToF (M0169): 10 FPS, decimator 5, exposure_max_us: 6000

Tracking front (OV7251): 30 FPS, preview + raw preview enabled, preview_width and preview_height 640 and 480 respectively.

With this configuration, CPU/GPU temperatures rise quickly and go beyond 80 °C. After running for some time, the ToF camera stops working, and the HiRes feed becomes unstable with significant latency and frame delays, as shown in the attached screenshots.

@Piyush-Singh Also take a look at CPU usage of voxl-portal and voxl-camera-server
