Production Testing

Overview

The purpose of this test procedure is to identify connectivity issues, poor soldering, and potential manufacturing defects in the AD-ACEVSECRDSET-SL board. Some issues are directly identified by explicit part-targeted tests, while others are detected implicitly by running adjacent tests.

Test Process

Wi-Fi Setup

Ensure the Raspberry Pi is connected to Wi-Fi before starting the tests. If the test screen is already running, you will need to exit it first to configure the network connection.

  • After the Raspberry Pi boots, press Ctrl+C to exit the test screen.

  • Click on the Wi-Fi icon in the system tray and select the network you want to connect to.

    Figure 3 Wi-Fi Network Selection

  • Type in the password and connect to the network.

  • After connecting successfully, reboot the Raspberry Pi by navigating to the application menu, selecting Logout, then choosing Reboot from the shutdown options.
