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.

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. .

2.4 GPIO Test
This test focus on the following 16-ch GPIO pin definition:
J5[GPIO2_0,GPIO2_1, ,GPIO2-2,GPIO2-3,GPIO2-4,GPIO2_5,GPIO
2_6,GPIO2_7].
J31[ GPIO2_16,GPIO2_17,GPIO2_18,GPIO2_19,GPIO2_20,GPIO2
_21,GPIO2_22,GPIO2_23].
Test Principle:
[Gpio_test 0] test the situation when gpio does not have external
connection, set all pin to low level or high level, through external
measure gpio actual level to confirm 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 gpio is normal.
Test Process & Result：
Run gpio test program [ gpio_test]
./gpio_test
It hints the below information:

Illustration: [gpio_test <device> 0] set gpio high level and low level
[gpio_test <device> 1] obtain gpio level
2. J5 and J31 GPIO is without external signal, execute
./gpio_test /dev/qiyang_imx6_gpio 0
As the above picture shown, set each [GPIO] to low level. Use
multimeter to measure corresponding GPIO’s actual level value to
confirm GPIO is normal or not. Then press [Enter] to set all GPIO to high
level, to measure corresponding GPIO’s actual level value to confirm
GPIO is normal or not.

2.5. Serial Port Test
There are 5-ch serial ports: J6 is as the debug UART. The other 4-ch
could be used as the RS232 serial port.
COM1(J31) and COM2(J31) are 5 wire serial ports and multiplexes
with RS485 interface.
COM3(J2) and COM4(J2) is 3 wire serial ports.
This test program only aims at testing of common RS232.
The relations between serial port and hardware:

Test Principle：
Test program realizes that 1 serial port send character data
“/dev/ttymxcx" test string!!”every other 1s, X is actual testing device node,
through multithreading way to block reading serial ports data and then
print.
Test Process & Result：
When do serial ports testing, PC needs 2 serial ports
②.One connect to debugging port for interaction
③.One connect to under test ports to receive and transmit data
If there is only 1 serial port, port connect to under test ports , connect
development board by network cable. Through [telnet] function to log in
development system as debugging ports operation.
Development board defaulted IP address is 192.168.1.71. Click start
button on PC, select [RUN], then type [cmd] and click confirm.
