Good afternoon! I encountered a problem when working with the UC-788 Rev camera.B with OV9281 sensor (black and white sensor with MIPI CSI-2 interface) on Jetson Orin NX DevKit platform. I am using JetPack 6.2 (L4T 36.3.0) and the 5.136-tegra kernel.
To connect the camera, the driver provided by the link taken from the Arducam forum was used:
When connecting the camera and using the configured parameters, I get a “broken” picture (noise, stripes), despite the fact that all parameters, including the capture format, are set correctly, as I understand it. The attached image shows that instead of the expected image, only noise is output. The problem seems to be related to incorrect initialization of the sensor or incorrect loading of registers via I2C, but I did not find a clear solution.
System information:
Camera: UC-788 Rev.B
Sensor: OV9281 (black and white, MIPI CSI-2)
Platform: Jetson Orin NX DevKit
JetPack: 6.2 / L4T 36.3.0
Core: 5.136-tegra
Questions:
Can you tell me if such errors (error 22 when accessing the sensor’s I2C device) are a known problem with the OV9281 driver?
Perhaps it is necessary to make changes to the initialization settings (I2C initialization, sensor register configuration) for the OV9281 to work correctly on this platform (Jetson Orin NX, JetPack 6.2, core 5.15.136-tegra)?
Do you have any updates or patches to fix this issue?
What additional parameters or tests can be performed to diagnose and correct the situation?
I would be grateful for the prompt response and recommendations provided, as this problem significantly hinders the further development of the project.
