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
