On this page environmental stress testing results of iMX6 Rex Development kit are displayed. Detailed instructions about how to setup iMX6 Rex Development kit are also shown. The original article can be accessed on the iMX6Rex.com website.
Hardware configuration
For our testing we used following hardware configuration (you can use anything you have, just be aware of temperature range of the components fitted on your board):
- 3x iMX6 Rex Development kit in modified Pro configuration
- 1GHz iMX6 Quad CPU - extended temperature range (-20°C to +105°C)
- 4x 4Gb DDR3 Memory chips - commercial temperature range (0°C to +95°C)
- 1GBps Ethernet PHY Tranciever KSZ9021RN - commercial temperature range (0°C ~ +70°C)
- 1x iMX6 Rex Development kit in alternative Pro configuration
- 1GHz iMX6 Quad CPU - extended temperature range (-20°C to 105°C)
- 4x 2Gb DDR3 Memory chips - commercial temperature range (0°C to +95°C)
- 1GBps Ethernet PHY Tranciever KSZ9021RN - commercial temperature range (0°C to +70°C)
Note: An industrial iMX6 Rex heatsink was used. With a bigger heatsink you can achieve higher temperature.
The setup in environmental chamber:

Test description
The main purpose of this test is to check memory stability of iMX6 Rex Module. During the test you will be running:
- 4 threads of extensive memory stress test
- 4 threads of CPU stress test
This is the main command used for the test:
# stressapptest -s 600000 -M 768 -m 4 -C 4 -W --printsec 600 -l /home/ubuntu/testing-env-chamber/stressapptest.log
Detailed description about how to setup and run the whole test can be found in section How to prepare the test. It describes all the scripts and explains log files.
Testing Results
Here are the results of the testing. In the picture below you can see the temperature profile which was set during the testing:

Switch ON/OFF test - PASS
Test description: Boards were switched OFF , left OFF for 10 minutes and then switched ON. These tests were done several times for temperatures between -30°C to -35°C and for a temperature +70°C. All the boards booted up successfully.
