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:

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:

2.10 RS485
SBC-EC8800 can be used as an RS485 device, the connect principle is shown in following diagram. Users need to
find the corresponding pins according to the schematics, connect the RS485 interface on SBC-EC8800 to another
RS485 device with cables.
Enter the following instructions from one device:
root@embest:~# ./uart_test2 /dev/ttyS3 9600 1
send_buf size =50
/dev/ttyO3 input bandrate value = 9600 flag = 1 set bandrate is 9600
[databits = 8, stopbits= 1, parity= 78]
[SET CRTSCTS]
uart setup done!!!
uart fd = 3
temp = 1

It will be working at receive status.
Enter the following instructions from the other device:

9 send data successful
10 send data successful
Send 10 data.
Check if the receive device receive data correctly.
2.11 CAN
SBC-EC8800 can be used as a CAN device. As SBC-EC8800 has 2 CAN modules, we can make an internal
communication test use both CAN0 and CAN1 by connect them together. Connect Pin 33 and 34, Pin 35 and 36,
Pin 37 and 38 in J5.
Test method as follows:
1. Open CAN0 and CAN1
root@embest:~# ip link set can0 type can bitrate 50000 triple-sampling on
root@embest:~# ip link set can1 type can bitrate 50000 triple-sampling on
root@embest:~# ip link set can0 up
root@embest:~# ip link set can1 up
2. CAN1 receive data, CAN0 send data to CAN1
root@embest:~# candump can1&
root@embest:~# cansend can0 123#11223344556677
3. Shut off the device after test finished.
root@embest:~# ip link set can0 down
root@embest:~# ip link set can1 down
Users can do the transceiving test according to the above instructions, and set different baudrate to communicate.

SBC-EC8800 User Manual
Embest Technology Co. Ltd | http://www.embest-tech.com 17
Note you must shut off the device before set a different baudrate. Effective baudrate contains:

The board can communicate at the above baudrate. Users can also test with other baudrate to see if the device
works too. The CAN module can also connect a CAN module from other board to test.
2.12 Network

2. Slave Device
Connect J10 to PC, open the device manager, and check if the following device is recognized:
2.14 WIFI
2.14.1Configure WIFI Antennas
After the first boot, the wifi is working at 2.4GHz frequency in default, if you need to use the 5GHz frequency,
please configure the WIFI module at first. Here we provide two methods:
1. Enter the path /usr/sbin/wlconf, enter command ./ configure-device.sh
root@embest:~# cd /usr/sbin/wlconf/

SBC-EC8800 User Manual
Embest Technology Co. Ltd | http://www.embest-tech.com 19
root@embest:/usr/sbin/wlconf# ./configure-device.sh
Then enter “y 1837 y 2 2”according to the prompt:
Please provide the following information.
Are you using a TI module? [y/n] : y
What is the chip flavor? [1801/1805/1807/1831/1835/1837 or 0 for unknown] : 1837
Should Japanese standards be applied? [y/n] : y
How many 2.4GHz antennas are fitted? [1/2] : 2
How many 5GHz antennas are fitted? [0/1/2] : 2

2. Enter path /usr/sbin/wlconf, enter the command:
root@embest:~# cd /usr/sbin/wlconf
root@embest:/usr/sbin/wlconf# ./wlconf -o /lib/firmware/ti-connectivity/wl18xx-conf.bin -I
/usr/sbin/wlconf/official_inis/WG7833-B0A_INI_rev1.ini
You just need to choose one method, then you can use 5G WIFI. This configuration support 2.4G, too. The
operation only need to be executed before the first use of WIFI. You don’t need to execute again when you open
WIFI or boot system again.
2.14.2Connect WIFI
