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.

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.

2.3 Watchdog Test
Test Principle:
Hardware Watchdog, GPIO5_20 enable Watchdog, GPIO5_18
executing ‘Feeding Dog’ operations.
Test Process &Result:
1.Boot Watchdog, and execute ‘feeding dog’operations. You can see the
system will not reboot. Press [Ctrl+C] to exit the program.
./watchdog_feed_test /dev/qy_watchdog

FAQ:
1. The system did not reboot, after executing
[./watchdog_notfeed_test]. Please check the watchdog’s chipset if
it is damaged.
2.4 GPIO Test
This test aim at the following 16 channel GPIO Definition:
J16[GPIO1_4、GPIO1_7、GPIO1_8、GPIO1_9、GPIO7_11、
GPIO7_12、GPIO7_13、GPIO4_5]
J31[GPIO4_24、GPIO4_26、GPIO4_28、GPIO4_30、GPIO5_5、
GPIO5_7、GPIO5_9、GPIO5_11]
Test Principle:
[Gpio_test 0] test the situation when gpio do not have external
connection, set all pin to low level, then set them to high level, through
external measure [gpio] actual level to confirm whether gpio is normal or
not.
[Gpio_test 1] will read external level signal directly, user can
compare read level data and connected level data to confirm whether
[gpio] is normal or not.

2.5. Serial Port Test
There are 3-ch serial ports on IAC-IMX6-KIT mainboard: 1-ch serial
port is used for debug port(J6), other 2-ch serial port are regarded as
common RS232 port or RS485.
This test program only aims at testing of common RS232.
Serial Port and hardware relations:

at the same time, through multithreading way, block read serial ports data
and print.
Test Process & Result:
When testing, you may need to use 2-ch serial port on PC:
(1)1-ch is used for connecting the debugging serial port, it is used for
interaction.
(2)1-ch is to connect to the serial port which is under test, it is used
for the date’s receiving and transmitting.
If there is only 1-ch serial port on PC mainframe, the serial port is
connected to the serial port under test, connect to the mainboard by
network cable, log in mainboard system by [telnet], operate it as the
debug UART.
The mainboard’s default IP address: 192.168.1.71,click [Start] button
on PC, select [Run], input [cmd],click [Confirm].
