Excellent products need to undergo rigorous product testing before they can withstand market validation.
The production testing software developed by the ArmSoM team is used to quickly identify good and bad product functions and devices during mass production, i.e. key FCT (Functional Test) testing, thereby improving production efficiency and detection accuracy.
ArmSoM professional production testing software is used to ensure the quality and stability of each mass produced product.
Before mass production, the ArmSoM team will conduct several rounds of professional functional testing and performance stress testing on the products to ensure product quality and stability.
Excellent products require multiple comprehensive functional and performance stress tests to withstand market validation.
rk-msch-probe-for-user is an official tool used to monitor and collect statistics on system DDR load and bandwidth usage. It can display real-time DDR load and bandwidth information.
Use the rk-msch-probe-for-use tool to monitor and collect statistics on system DDR load and bandwidth usage.
The rk-msch-probe-for-user tool needs to run in frequency lock mode. Set DDR frequency lock to the highest frequency 2112MHz

This article outlines high temperature testing of the ArmSoM-W3 for RK3588 mass production testing.
Test Principle: Place ArmSoM-W3 boards in 70°C environment,and perform 2000 software reboots, observing if boards boot normally.
Test Time: May 9, 2023 9:55AM - May 10, 2023 13:50PM
Test Tools: 6 serial ports, 6 boards (1 green core board, 5 blue core boards), power supply, computer, HDMI cables and displays
Test Steps:
Prepare 5 ArmSoM-W3 boards, connecting serial ports and power supply, and place all in chamber.
Open MobaXterm to record logs during test.
Raise chamber to 70°C, holding for 4 hrs, and check if it can normally boot. Power cycle every 15 mins, repeating 2000 times. Check if it can normally boot.
Check logs print for actual number of board reboots , and check for anomalies during the power cycle.
Test Results: There are 5 boards operated normally after 1000 software reboots completed.
Test Principle: Place ArmSoM-W3 boards in 70°C environment, and perform 2000 power cycle reboots, observing if boot is abnormal.
Test Time: May 10, 2023 17:52PM - May 12, 2023 9:02AM
Test Tools: Serial ports, 6 boards(1 green core board, 5 blue core boards), power cycling timers(Automatically power off, power on)
Test Software: MobaXterm to record logs and save.
Test Steps:
Prepare 5 ArmSoM-W3 boards, connecting power supply of timers and serial ports connected to computer. Place all in chamber.
Open MobaXterm to record test logs.
Set timers to 25s boot and 10s shutdown cycles.
Raise chamber to 70°C, holding for 4 hrs, and check if it can normally boot. Power cycle every 15 mins, repeating 2000 times. Check if it can normally boot.
Check logs print for actual number of board reboots , and check for anomalies during the power cycle.
Test Results: There is no anomalies detected in hardware reboot test after 1000 power cycle reboots completed and reboot counts differed by 1-2 due to margin of error.
