RK3588 platform production test of ArmSoM product high temperature environment test

1 Introduction

• General catalog of columns

• The ArmSoM team will conduct several professional functional tests and performance stress tests on the product before mass production to ensure the quality and stability of the product

• Excellent products must undergo rigorous multiple comprehensive functional tests and performance stress tests before they can stand the test of the market

• This article summarizes the ArmSoM-W3 high temperature test of RK3588 platform production test

2. ArmSoM-W3 High Temperature Test Solution

• Perform 2000 software system restart tests in a high temperature environment of 70°C
• Perform 2000 times of power plug-in and hardware restart test in a high temperature environment of 70°C
• High-intensity operation for 24 hours in a high-temperature environment of 70°C

3. 70℃ high temperature software restart test

• Test principle: The ArmSoM-W3 development board is placed in a high temperature environment of 70°C for 2000 software system restart tests to observe whether the development board can start normally.

• Test time: May 9, 2023 at 9:55 – May 10 at 13:50

• Test tools: 6 serial ports, 6 development boards (one green core board, five blue core boards), power supply, computer, HDMI cable and display

• Test steps:

  1. Prepare 5 ArmSoM-W3 development boards, all connected to the serial port and power supply, and put them all in the incubator
  2. Open the MobaXterm software to record the log print of the test period
  3. The temperature of the incubator is raised to 70°C for 4 hours to see if it can be turned on normally; after 15 minutes of shutdown, turn on the power and turn it on again, and the cycle is 2000 times. See if the development board can start normally.
  4. According to the log printing, check how many times the RK3588 - ArmSoM-W3 development board is actually turned on and off, and check whether there is any abnormality during the power supply of the development board.

• Test results: After 1000 software restarts, all 5 development boards are running normally.

4. 70℃ high temperature power plug and plug hardware restart test

• Test principle: ArmSoM-W3 development board is placed in a high temperature environment of 70°C for 2000 times of power plug and hardware restart test, and observe whether the development board starts abnormally.

• Test time: 17:52, May 10, 2023 – 9:02, May 12, 2023

• Test tools: serial port, 6 development boards (one green core board, five blue core boards), timer (automatic power off, power on)

• Test software: MobaXterm software records the log printing during the test period, and saves the log data.

• Test steps:

  1. Prepare 5 pieces of ArmSoM-W3 development boards, connect the timer power supply, and connect the serial port to the computer. Put it all in the incubator
  2. Open the MobaXterm software to record the log print of the test period
  3. The timer sets the startup time of the development board to 25 seconds and the shutdown time to 10 seconds.
  4. The temperature of the incubator is raised to 70°C for 4 hours to see if it can be turned on normally; after 15 minutes of shutdown, turn on the power and turn it on again, and the cycle is 2000 times. See if the development board can start normally.
  5. According to the log printing, check how many times the RK3588 - ArmSoM-W3 development board is actually turned on and off, and check whether there is any abnormality during the power supply of the development board.

• Test results: 1,000 times of hardware power-off restart, the difference between the number of power-on and off times is within the error range, and the hardware restart test found no abnormalities.

5. 70℃ high temperature operation test

• Test principle: ArmSoM-W3 development board is placed in a high-temperature environment of 70°C for 24 hours with high intensity, and observe whether the operation of the development board is abnormal.

• Test time: 9:55, May 13, 2023 – 13:50, May 14, 2023

• Test tools: 6 serial ports, 6 development boards (one green core board, five blue core boards), power supply, computer, HDMI cable and display

• Test steps:

  1. Prepare 5 ArmSoM-W3 development boards, all connected to the serial port and power supply, and put them all in the incubator
  2. The development boards are all connected to the serial port, and the log printed by the serial port is saved when the machine is turned on and off.
  3. Heat the temperature of the incubator to 70°C to keep the value for 4 hours, start the high-performance software to run, and check whether the development board is abnormal during operation.
  4. Check whether the RK3588-ArmSoM-W3 development board is abnormal during operation according to the log printing

• Test results: After 24 hours of high-temperature and high-intensity operation at 70°C, the five development boards are all operating normally.
