**Part 2 Interface Test **
Ethernet test
The MYZR-RK3399 evaluation board has a Gigabit Ethernet port.
| Evaluation model | Interface Location | Interface Rate Standard | System Interface |
|---|---|---|---|
| MYZR-RK3399-EK314 | P19 | 10/100/1000Mbps | eth0 |
Test operation
Configure the computer's wired network card IP to 192.168.18.18。
Connect this network port of the development board to the computer network port with a network cable.
Configure the development board network port:
=====> Input: ifconfig eth0 192.168.18.36
Test network port
=====> Input: ping 192.168.18.18 -c 2 -w 4 =====> Output： --- 192.168.18.18 ping statistics --- 2packets transmitted, 2 packets received, 0% packet loss
Test Results
“0% packet loss”表示测试通过。

| P5-6 | GPIO2_D3 | 91 | |
| P5-7 | GPIO4_D0 | 152 | |
| P5-8 | GPIO4_C6 | 150 |
GPIO output test
Configure P8-3 to output high and low level operation methods:
=====> Input:
＃ OUT_IO_NUMBER=92
Export GPIO
＃ echo ${OUT_IO_NUMBER} > /sys/class/gpio/export
Set GPIO direction
＃ echo out > /sys/class/gpio/gpio${OUT_IO_NUMBER}/direction
Controlling the output level
＃ echo 0 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value
＃ echo 1 > /sys/class/gpio/gpio${OUT_IO_NUMBER}/value
Test pin P8-3 with a multimeter
GPIO input test
configure P8-3 input:
Set the IO number of the GPIO to be tested
＃ IN_IO_NUMBER=91
Export GPIO
＃ echo ${IN_IO_NUMBER} > /sys/class/gpio/export
Set GPIO direction
＃ echo in > /sys/class/gpio/gpio${IN_IO_NUMBER}/direction
View input level
cat /sys/class/gpio/gpio${IN_IO_NUMBER}/value
ADC-KEY test
| Evaluation model | Interface Location | Attribute | KEY attribute |
|---|---|---|---|
| MYZR-RK3399-EK314 | SW5 | adc-keys | Volume UP |
| SW4 | adc-keys | Volume Down | |
| SW3 | adc-keys | Home | |

RTC Test
test introduction
Affected by express shipping, the MYZR-RK3399-EK314 series evaluation board is shipped without batteries. Please prepare your own coin-cell battery and install it on the evaluation board before testing the RTC. The battery holder of MYZR-RK3399-EK314 is in the "BT1" position on the back of the bottom plate.
Test operation
1. Power off and restart the device to view the current system time and hardware time:
=====> Input: date =====> Output： Thu Aug 6 05:35:17 UTC 2012
2. View the current RTC chip clock:
=====> Input: hwclock =====> Output： Thu Aug 6 05:35:59 2012 0.000000 seconds
3. Set the system clock and synchronize to the RTC chip
=====> Input: date -s "2019-07-04 12:30:30"
4. Write system clock to hardware clock
=====> Input: hwclock -w
Test Results
The clock you see after step 3 is the newly set clock.
Audio playback test
test introduction
This test verifies the audio capabilities of the evaluation board by playing audio files.
- Test operation **
- Test operation **
