Preface: Even though QSC is installed on your Windows or Linux PC, its primary mission is to manage the Linux operating system that lives on your Target Development Board. QSC v1.21.0 knows exactly how to handle projects based on “Long Term Support Kernels” and provides the specific tools and patches required for them.

Background: To enable this within your qsc-cli workspace, follow these steps to modify your build configuration:

Step 1. Log in to the CLI
bash

qsc-cli login -u <your_email_address>

Step 2. In the context of the Qualcomm QRB4210 (RB2) and the Qualcomm Linux SDK, “enabling the SocketIO interface” typically refers to configuring a high-speed communication transport layer used in the Robot Operating System (ROS) or for high-speed sensor data between subsystems.

To enable this within your qsc-cli workspace, follow these steps to modify your build configuration:

Step 3. Identify the Required Metadata Layer

Socket-based transport optimizations, such as QRB ROS transport for zero-copy message passing, are often contained in the Qualcomm Intelligent Robotics (QIRP) SDK layers. Ensure you have the meta-qcom-qirp (or similar) layer in your workspace

Step 4. Update your bblayers.conf

Step 5. Enable via Kernel Menuconfig (If Hardware Socket/Interface)

If you are referring to a specific hardware-backed socket interface (like a virtualized socket for a DSP or NPU), you may need to enable it in the kernel:

Enter your build environment via qsc-cli.

Run the devtool to modify the kernel configuration:

Bash

devtool menuconfig linux-qcom-base

Search (using /) for SOCKET or the specific interface driver name (e.g., AF_QIPCRTR for Qualcomm IPC Router sockets).

Set it to <*>

Vulnerability details: Improper authorization in Qualcomm Software Center
