Ⅰ. Preparation
Before testing, please read QY-IMX6S Linux User Manual. pdf, and
connect to the board according to this manual.
Power on mainboard, after system starts, then input root user to enter
into file system of the board, as the following picture shown:
Mainboard test program in [/usr/test] directory, please switch to this
directory, the following testing operations will be done in this directory.
cd /usr/test/
ls

Ⅱ. Mainboard Test
2.1 Buzzer Test
QY-IMX6S mainboard use [GPIO 6_31] to control the buzzer on the
board. When set to low level, buzzer does not work; when set to high
level, buzzer will work.
Test Principle:
This test is to realize buzzing.
Test Process and Result：
Run buzzer testing program [buzzer_test]
Illustration: [buzzer_test <device>0] buzzer does not work, buzzer
can be closed.
[buzzer_test <device> 1] buzzer does work.
1. Open buzzer, the mainboard is buzzing continuously, press [Ctrl+C]
to exit the program.

2.2 RTC Test
QY-IMX6S mainboard adopts I2C2 connect DS1338 Chip on the
base board as external hardware clock. Please confirm that you put on the
battery before testing RTC.
Test Principle：
Set system time through [date] system command, and then write
system time into hardware clock through [hwclock] command. Through
[rtc_test ]program to read hardware timer and print it.After powering off,
restart to check whether the clock is accurate.
Test Process & Result：
1.Execute [date] command on the board and check the current system
clock.
date
2.Set system clock through [date] command, for example, to set on
current PC display time.

3.Use [hwclcok] command to write system time into hardware time
chip.
[ hwclock –w]
4.Check system and hardware clock by [date] command and
[hwclock ]command.
5.After setting successfully, execute [rtc_test] test program.
./rtc_test/dev/rtc0

After the program prints 10 of the RTC time, then exit the program.
Or you can use [Ctrl+c] to exit the program early.
RTC works accurately, no losing seconds.
6.Powering off, then power on to check system and hardware clock by
using [date] and [hwclock] command, to check time is saved or not and
whether works normally.
7.After comparing with PC time, there is no error. If need to test long
time work’s accuracy, you can separate power off and power on aging test
for several days or weeks or months to test the time error.
Before published, our board has been tested for aging test for 1 month,
and the time error does not exceed 2S.
As to our delivery goods, we will make it for aging test for more than
24 hours, and time error does not exceed 1S. .
