Hi Team

We are using this camera LI-IMX715-MIPI-D-HOLOSCAN-080H from Leopard Imaging.

Platform - Jetson AGX Orin - Jetpack 6.2.1

HSB - Lattice HSB board with latest firmware flashed

Holoscan SDK - 2.3.1

We followed this https://docs.nvidia.com/holoscan/sensor-bridge/latest/index.html and everything set perfectly. Running this example “$ python3 examples/linux_imx715_player.py“ gives following i2c error.

hello ahamedmuqthar,

since it’s the error regrading to i2c communication.
did you verified this sensor driver on AGX Orin via CSI connector?

hello JerryChang

I connected this camera directly to the MIPI connector on the AGX Orin. However, when I run v4l2-ctl --list-devices, no video devices are detected, and nvgstcapture-1.0 only opens a blank window.

Could you please help me determine if this might be a driver-related issue?

I appreciate your help.

hello ahamedmuqthar,

this should be driver bring-up issue.

you may running Jetson-IO to configure CSI connector. for instance, $ sudo python /opt/nvidia/jetson-io/jetson-io.py as you can see.. it’s not support IMX715 by default.
you must apply kernel update to enable IMX715, please contact with sensor vendor for the support drivers.
