This information describes changes to image composition in QIR SDK from Qualcomm® Linux® 1.0 to Qualcomm Linux 2.0.
For build system changes, including KAS setup, layer synchronization, and build commands, see Qualcomm Linux Migration Guide.
Changes in supported hardware
| Hardware | QIR SDK for Qualcomm Linux 1.0 | QIR SDK for Qualcomm Linux 2.0 |
|---|
| Qualcomm DragonwingTM RB3 Gen 2 Vision Development Kit | Yes | No |
| Qualcomm DragonwingTM IQ-9075 Evaluation Kit | Yes | Yes |
| Qualcomm DragonwingTM IQ-8275 Evaluation Kit | Yes | Yes |
NoteFrom Qualcomm Linux GA1.8, the QIR SDK stops the support for RB3 Gen 2 Vision Development Kit.
Changes in image composition model
QIR SDK uses different image composition model for Qualcomm Linux 1.0 and 2.0 releases. Following are the detailed differences.
QIR SDK for Qualcomm Linux 1.0
For Qualcomm Linux 1.0, QIR SDK uses a single image recipe (qcom-robotics-full-image). You can select from two build variants by setting QCOM_SELECTED_BSP at build time:
| Build variant | Description |
|---|
base | Provides a pure upstream and open-source software stack without Qualcomm proprietary software and power/performance value adds. |
custom | Provides a richer set of functionalities and includes Qualcomm’s value adds like SDKs and power performance improvements. |
NoteFrom Qualcomm Linux GA1.8, the base build variant was removed for IQ-9075 Evaluation Kit and IQ-8 Beta Evaluation Kit.
QIR SDK for Qualcomm Linux 2.0
The base/custom variant model is replaced by two separate image recipes, each built with a different Qualcomm Linux overlay configuration.
Qualcomm Linux overlays are modular, value-added components — sources or prebuilt binaries for technologies such as audio, camera, graphics, video, and sensors — that integrate with upstream components so you can choose between the upstream and Qualcomm technology stacks. They are delivered as recipes in the meta-qcom BSP OpenEmbedded layer, letting you leverage hardware capabilities and optimizations tailored for Qualcomm SoCs. For details, see Qualcomm Linux overlay overview.
| Image recipe | Description |
|---|
qcom-robotics-image | Provides an open-source image that includes: ROS 2 Jazzy, open-source qrb-ros packages, simulation samples, third-party drivers, and the QIR SDK artifacts. No proprietary dependencies. Built with overlay config 1. |
qcom-robotics-proprietary-image | Includes all components from qcom-robotics-image. It also provides qrb-ros packages that depend on Qualcomm proprietary libraries, including camera, video, audio, colorspace conversion, and all the AI sample applications. Built with overlay config 2. |
