Ⅰ. Preparation
Before testing, please read QY-IMX6-KIT Linux User Manual. pdf,
and connect to the mainboard according to that 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 is 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
IAC-IMX6-Kit 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 works.
Test Principle:
This test is to realize the buzzer to work.
Test Process & Result:
Run buzzer test program [buzzer_test]
Illustration: [Buzzer_test 0] buzzer does not work, close buzzer
[Buzzer_test 1] buzzer works.
1. Open buzzer, hear the buzzer is buzzing continuously on board.
Press [Ctrl+C] to exit the program.
./buzzer_test /dev/qiyang_buzzer 1
2. Close buzzer, press [Ctrl+C] to exit the program.
./buzzer_test /dev/qiyang_buzzer 0

the back plane as the external hardware clock. Please confirm you have
already installed the battery on back plane 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 ]test program to read hardware clock and print it. After powering
off, then restart it to check whether the time 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
according to the current PC time.
#date 022710412014 /* month day hour minute year */
3.Use [hwclcok] command to write system time into hardware clock
chip.

4.Check system and hardware clock by [date] and [hwclock ]command.
5.After setting successfully, execute [rtc_test] test program.
./rtc_test /dev/rtc0

The current program will print 10 pcs of hardware time, then exit. If
you want to exit early, please press [Ctrl+C] to check whether the RTC
clock works accurately, no losing seconds.
6.Power off, then power on to check system and hardware clock again.
To check whether the time is saved or not, whether the time is accurate.
7.After comparing with PC time, there is no error. If you need to test
long time work’s accuracy, you can power off and power on separately
for aging test for several days or weeks or months to test the time error.
