1.2 System Boot from SD Card
Install the Serial Communication software (e.g. SecureCRT), select the corresponding port number, baudrate
as 115200, data bits as 8, stop bits as 1, parity as none.
Connect the DEBUG interface (CN4) to the serial interface of PC with a USB to TTL module.
Insert the MicroSD card into the card slot (TF1).
Press S3 button, then powered the board with a 5V, 2A power. Release S3 after the power reset.
Wait for the system boot up, then the serial output will show the following information:

1.3 System Boot from EMMC
Copy the SBC-PH8700_Shipment_Image_EMMC_Rev01.img to a U-disk.
Refer to 1.2, boot the system from SD Card, then plug the U-disk to P3;
Execute the following instructions on the serial terminal:
root@embest:~# ls /dev/sd*
/dev/sda /dev/sda1
root@embest:~# mount /dev/sda1 /mnt/
root@embest:~# dd if=/mnt/SBC-PH8700_Shipment_Image_EMMC_Rev01.img of=/dev/mmcblk1
Note: Burn the EMMC takes a long time, please wait patiently.
Then power reset the board to boot from EMMC (Don’t press S3 anymore).

Chapter 2 Function test
First of all, please refer to Chapter 1.1 and boot up the system. Then test the functions according to the following
guidance.
2.1 LED
User can control LED (D2, D3) indicators on SOM-PH8700 Board. After the system boot up, please execute the
following instructions in serial terminal to implement the test; (D2 is attached to user_leds_d2, D3 to
user_leds_d3)
Light out LED:
root@embest:~# echo 0 > /sys/class/leds/user_leds_d2/brightness
root@embest:~# echo 0 > /sys/class/leds/user_leds_d3/brightness
Light up LED:
root@embest:~# echo 1 > /sys/class/leds/user_leds_d2/brightness
root@embest:~# echo 1 > /sys/class/leds/user_leds_d3/brightness
2.2 RTC
Execute the following instructions on the serial terminal:
Check the current system time:
root@embest:~# date
Sat Jan 1 00:02:07 UTC 2000
Set current time as 10:46, March 9, 2016
root@embest:~# date 030910462016
Wed Mar 9 10:46:00 UTC 2016
Write system clock into RTC:
root@embest:~# hwclock –w
Read RTC value:
root@embest:~# hwclock
Wed 09 Mar 2016 10:46:23 AM UTC -0.432561 seconds
The above information indicates that the hardware clock-RTC-has been set to March 9, 2016, so the system clock
is saved in the hardware clock.
Reboot the system and check the current system time:
root@embest:~# date
Wed Mar 9 10:46:45 UTC 2016
