Production Testing

Overview

The purpose of this test procedure is to identify connectivity issues, poor soldering, and potential manufacturing defects in the ADRD8012-01Z board. Some issues are directly identified by explicit part-targeted tests, while others are detected implicitly by running adjacent tests.

Test Duration

Step Description	Estimated Time (minutes)
Test bench setup	5 min
Software test	10 min
Total time	15 min

Test Requirements

Required Hardware

• 1 x ADRD8012-01Z board (device under test)

• 1 x AMD KRIA KV26 System-on-Module

• 1 x microUSB to USB cable

• 1 x SD card for the DUT

• 1 x wire for UART testing

• 4 x Digilent Pcam 5C cameras

• 4 x AD-GMSL716MIPI-EVK (GMSL serializer evaluation kit)

• 4 x Fakra cables that connect to the DUT board

• 1 x QNA-T310G1S and SFP+ to thunderbolt cable

• Power supply for ADRD8012-01Z board

• 1 x GPIO loopback connector

• 1 x test laptop and power cable

Required Software

• Test image provided on the testing laptop

Required Setup

• Insert the SD card into the ADRD8012-01Z device under test.

• Attach the KRIA system-on-module on the ADRD8012-01Z.

• Plug the microUSB cable into the ADRD8012-01Z and into the laptop.

• Connect the Rx and Tx pins of the UART connector using a wire.

• Plug in the SFP+ cable into the carrier and into the QNA-T310G1S.

• Power the QNA-T310G1S using a Type C thunderbolt cable and plug it into the laptop.

• Attach the GPIO loopback on the GPIO connector.

• Connect each Pcam 5C camera to an AD-GMSL716MIPI-EVK serializer, then connect each serializer to one of the ports on the quad mini Fakra connector (PORT 2) on the ADRD8012-01Z board.

Test Process

Running the Tests

• After completing the test setup, power on the test laptop and you will see a login screen.

  

  Figure 4 Test Laptop Login Screen

• Enter the password analog to login.

• When the menu appears, type 1 in the terminal to start the System Test.

  

  Figure 5 Test Menu

• Follow the on-screen prompts:

  • When prompted, verify the MicroUSB cable is connected to the carrier UART and press ENTER.

  • When prompted to insert the GPIO loopback, press ENTER.

  • When prompted to connect the wire between UART Rx and Tx, press ENTER.
