Chapter 1 Quick Start
1.1 Burn the System Images to the SD Card
Firstly, you should prepare a SD card, which is no less than 2GB.
Then, download and install “Win32 Disk Imager”from https://sourceforge.net/projects/win32diskimager/.
Select the system image: SBC-EC8800-Release-REV01\image\SBC-EC8800-Release-SDcard-EMMC-REV01.img
Click “Write”button to burn the images:

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 (J13) to the serial interface of PC with a USB to TTL module.
Insert the SD card into the card slot (J2).
Power the board with a 5V, 2A power.
Wait for the system boot up, then the serial output will show the following information:
Enter username and password as “root”to login;
1.3 System Boot from SPI Flash
Refer to 1.2, boot the system from SD Card, press “Enter”when the serial terminal prints the following info:
U-Boot SPL 2015.07 (Jun 20 2016 - 17:15:48)
SPL: Please implement spl_start_uboot() for your board
SPL: Direct Linux boot not active!

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 (D8, D9) indicators on SBC-EC8800 Board. After the system boot up, please execute the
following instructions in serial terminal to implement the test; (D8 is attached to user_leds_d8, D9to
user_leds_d9)
Light out LED:
root@embest:~# echo 0 > /sys/class/leds/user_leds_d8/brightness
root@embest:~# echo 0 > /sys/class/leds/user_leds_d9/brightness
Light up LED:
root@embest:~# echo 1 > /sys/class/leds/user_leds_d8/brightness
root@embest:~# echo 1 > /sys/class/leds/user_leds_d9/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
