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 1GB.
Then, download and install “Win32 Disk Imager”from https://sourceforge.net/projects/win32diskimager/.
Select the system images file: 91200003_SBC-EC9100-SDcard_Shipment_Image_REV00.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 Uart Tx (Pin 8 in J10) and Rx (Pin 10 in J10) to PC with USB to TTL convertor.
Insert the SD card into the card slot J3.
Powered the board with a 5V, 2A power (J1).
Change the dial switch SW3 to 00, SW4 to 0010.
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 EMMC
Copy the 91200003_SBC-EC9100-EMMC_Shipment_Image_REV00.img to a U-disk;
Refer to 1.2, boot the system from SD Card, then plug the U disk to USB interface J8:
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/91200003_SBC-EC9100-EMMC_Shipment_Image_REV00.img of=/dev/mmcblk1
Note: Burn the EMMC takes a long time, please wait patiently.
If it is the first time to burn the EMMC, you need to Enable boot from EMMC user partition, see chapter 3.2.3.
Then you don’t need to do this operation anymore.
Power off the board after the burning finished, change the dial switch SW3 to 10, SW4 to 0110, plug out the SD
card, power on the board to boot from EMMC

Modify emmc_write value:

SBC-EC9100 User Manual
Embest Technology Co. Ltd | http://www.embest-tech.com 13
root@embest:~# vi emmc_write
E.g. Write “emmc write test”into the system
Write emmc instructions:
root@embest:~# dd if=emmc_write of=/dev/mmcblk1
mmcblk1: p1 p2
0+1 records in
0+1 records out
16 bytes (16 B) copied, 0.0396547 s, 0.4 kB/s
Read emmc instructions:

10+0 records in
10+0 records out
10240 bytes (10 kB) copied, 0.0179817 s, 569 kB/s
Check emmc_read value:
root@embest:~# cat emmc_read
emmc write test
Test passes;
2.5 GPIO
SBC-EC9100 have 4 pins which can be used as GPIO controlled output, they are:
-GPIO4 (Pin 8 in J9)
-GPIO5 (Pin 7 in J9)
-GPIO9 (Pin 23 in J9)
-GPIO132 (Pin 7 in J10)
Users can execute the following instruction to test GPIO function:
Example: Test GPIO4
1. Enable the GPIO and initialize it:
root@embest:~# echo 4 > /sys/class/gpio/export
root@embest:~# echo out > /sys/class/gpio/gpio4/direction
2. Set the level of pin and test the voltage of the pin:
root@embest:~# echo 1 > /sys/class/gpio/gpio4/value
Now the pin output should be high level

SBC-EC9100 User Manual
Embest Technology Co. Ltd | http://www.embest-tech.com 14
root@embest:~# echo 0 > /sys/class/gpio/gpio4/value
Now the pin output should be low level
Change the “4”to 5, 9, 132 in above instructions to test GPIO5 (Pin 7 in J9), GPIO9 (Pin 23 in J9) and GPIO132 (Pin
7 in J10).
2.6 LCD
Connect the screen module to J5,
4.3” LCD:
Open the uEnv.txt file from SD card, modify fdtfile=embest_fsl_sbc_ec9100_4.3inch.dtb
Then reboot the system;
7” LCD:
Open the uEnv.txt file from SD card, modify fdtfile=embest_fsl_sbc_ec9100_7inch.dtb
Then reboot the system;
Backlight test:
Execute the following instruction in the serial terminal
root@embest:~# echo 0 > /sys/class/backlight/backlight.9/brightness
echo from 0 to 7 to find the screen backlight change.
2.7 Touchscreen
Connect the screen module to J5, make sure fuse is written. Read the fuse value by the following instruction. (You
just need to set bit 20 and bit21 to 1, eg. 0x003000xx)
root@embest:~# cat /sys/fsl_otp/HW_OCOTP_CFG2
To set fuse value, execute the following instruction (xx change to the value you cat):
root@embest:~# echo 0x003000xx > /sys/fsl_otp/HW_OCOTP_CFG2
Note: The value of different board may not be same, but it has no influence on the test.
Enter the following instruction to make the touch calibrate function work:
root@embest:~# export TSLIB_TSDEVICE=/dev/input/event1
execute the following instructions on the serial terminal to implement the touch screen calibration program:
root@embest:~# ts_calibrate
Following the notes on LCD, click the “+”icon for five times to complete the calibration.
