If you purchased the Orange Pi 3 development board without the EMMC Flash chip, you can only start the system through the TF card. Etcher supports the following operating systems.<br>* Linux (most distributions, such as Ubuntu)* MacOS 10.9 and later* Windows 7 and later The Etcher software installation package can be downloaded from its official website https://etcher.io/, or it can be downloaded from the official tool of the Orange Pi 3 official website download page<br><br>=== '''Etcher installation method''' ===<br>* The installation method of Etcher in Windows is the same as that of ordinary software, so I won't go into details here.* Etcher is installed on Ubuntu and Debian systems as follows<div style="border:1px solid #dddddd;background:#f1f1f1;padding:5px;">1.Add Etcher Debian repository：<br>$ echo "deb https://dl.bintray.com/resin-io/debian stable etcher" | sudo tee /etc/apt/sources.list.d/etcher.list<br><br>2.Download the key<br>$ sudo apt-key adv --keyserver hkp://pgp.mit.edu:80 --recv-keys 379CE192D401AB61<br><br>3.Update and install<br>$ sudo apt-get update && sudo apt-get install etcher-electron<br><br>4.Uninstallation method<br>$ sudo apt-get remove etcher-electron<br>$ sudo rm /etc/apt/sources.list.d/etcher.list && sudo apt-get update</div><br>=== '''How to flash Linux firmware through Etcher''' ===<br>* First open Etcher, its interface is shown below<div>[[文件:Orange-pi-3-img24.png|800px]]</div>* Then use "Select image" to select the Linux firmware to be burned* Then insert the TF card, Etcher will automatically identify the corresponding drive* Finally, click “Flash!” To start burning.

After the programming is complete, turn off the power, remove the TF card, and then power on the Linux system in EMMC Flash automatically.<br><div style="border:1px solid #dddddd;background:#f1f1f1;padding:5px;">root@OrangePi:~# '''install_to_emmc'''<br><br>WARNING: EMMC WILL BE ERASED !, Continue (y/N)? y<br>Erasing EMMC ...<br>Creating new filesystem on EMMC ...<br><p style="padding-left:20px;">New filesystem created on /dev/mmcblk0.</p>Partitioning EMMC ...<br><p style="padding-left:20px;">Creating boot & linux partitions<br>OK.</p>Formating fat partition ... <p style="padding-left:20px;">fat partition formated.</p>Formating linux partition (ext4), please wait ...<p style="padding-left:20px;">linux partition formated.</p><br>Instaling u-boot to EMMC ...<br><br> Mounting EMMC partitions...<br>FAT partitions mounted to /tmp/_fatdir<br>linux partition mounted to /tmp/_extdir<br><br>Copying file system to EMMC ...<br><br><p style="padding-left:20px;">Creating "fstab"</p><br>*******************************<br> Linux system installed to EMMC.<br>*******************************</div><br>== '''Instructions for use of Linux system''' ==<br>=== '''Linux boot light description''' ===<br>* After booting, the on board LED light will first light up red, then the red light will turn off, and the yellow light will stay on.<br>=== '''Login account and password''' ===<br>* Username root, password: orangepi* Username orangepi, password: orangepi<br>=== '''extend rootfs partition''' ===<br> After the system running card is prepared, the file system rootfs partition should be expanded immediately.
