How to Configure Sensor DOL Virtual Channel Mode

Issue Overview

Users are encountering difficulties when attempting to configure the HDR DOL3 virtual channel mode on the Nvidia Jetson Orin Nano Dev board. The main symptoms reported include confusion regarding the support for DOL (Digital Overlap) in virtual channel mode and a lack of clear guidance on how to implement this configuration.

The issue arises specifically when users are trying to utilize the DOL Line Information Output Mode, which appears to function correctly. However, there is uncertainty about whether the Jetson Orin Nano supports the HDR DOL3 virtual channel mode, leading to frustration and stalled development efforts.

No specific hardware or software specifications were mentioned in the discussion, but it can be inferred that users are working with the Nvidia Jetson Orin Nano Dev board and associated software packages. The problem seems to be consistent among users attempting to implement this feature, significantly impacting their ability to utilize HDR functionalities effectively.

Possible Causes

• Lack of Support for DOL3: The primary cause of the issue is that DOL in virtual channel mode is not supported on the Jetson Orin Nano, as indicated by a user reply. This limitation means that users cannot configure this mode as intended.

• Misunderstanding of Capabilities: Users may have misconceptions about the capabilities of the Jetson Orin Nano regarding HDR and DOL configurations, leading them to attempt unsupported configurations.

• Documentation Gaps: Insufficient documentation or examples related to configuring HDR DOL3 virtual channel mode could contribute to user confusion and errors during setup.

Troubleshooting Steps, Solutions & Fixes
