| − | ==Buildroot简介==
| + | {{BurnLinuxToExtDrive-Rockchip/zh|NanoPC-T4}} |
| − | Buildroot是Linux平台上一个构建嵌入式Linux系统的框架，由Makefile脚本和Kconfig配置文件构成，旨在简化系统制作步骤，可实现一站式生成可烧写的系统固件，最终的固件包含boot-loader、kernel和rootfs，以及rootfs中的各种库和应用程序 (例如qt, gstreamer, busybox等)。<br />

| − | ==获取项目源代码==
| + | |
| − | ===安装 repo 工具===
| + | |
| − | 首先需要安装 repo 工具：
| + | |
| − | <syntaxhighlight lang="bash">
| + | |
| − | git clone https://github.com/friendlyarm/repo
| + | |
| − | cp repo/repo /usr/bin/
| + | |
| − | </syntaxhighlight>
| + | |
| − | ===下载项目源代码===
| + | |
| − | 有以下两种途径获取项目源代码，中国大陆用户建议使用方法1的途径下载:
| + | |
| − | ====方法一：使用网盘里的repo压缩包====
| + | |
| − | 网盘下载地址: [http://download.friendlyarm.com/{{#replace:{{#replace:{{BASEPAGENAME}}| |}}|/zh|}} 点击进入]<br />
| + | |
| − | 文件位于网盘的以下路径：sources/linuxsdk-friendlyelec-YYYYMMDD.tar (YYYYMMDD表示打包的日期)<br />
| + | |
| − | 从网盘中获取的 repo 压缩包在解压之后，需要执行一下以下命令做一次解包动作：
| + | |
| − | <syntaxhighlight lang="bash">
| + | |
| − | tar xvf /path/to/netdisk/sources/linuxsdk-friendlyelec-YYYYMMDD.tar
| + | |
| − | cd linuxsdk-friendlyelec
| + | |
| − | repo sync -l
| + | |
| − | </syntaxhighlight>
| + | |
| − | 用此方法得到的源代码版本是repo打包时的版本，如果想拉取到官方最新的版本，可以去掉 -l 参数，执行一次 repo sync, 例如：
| + | |
| − | <syntaxhighlight lang="bash">
| + | |
| − | cd linuxsdk-friendlyelec
| + | |
| − | repo sync
| + | |
| − | </syntaxhighlight>
| + | |
| − | ====方法二：从github下载====
| + | |
| − | <syntaxhighlight lang="bash">
| + | |
| − | mkdir linuxsdk-friendlyelec
| + | |
| − | cd linuxsdk-friendlyelec
| + | |
| − | repo init -u https://github.com/friendlyarm/buildroot_manifests -b master -m rk3399_linux_release.xml --repo-url=https://github.com/rockchip-linux/repo
| + | |
| − | repo sync -c
| + | |
| − | </syntaxhighlight>
| + | |
| − | ====同步项目到最新版本====
| + | |
| − | <syntaxhighlight lang="bash">
| + | |
| − | cd linuxsdk-friendlyelec
| + | |
| − | repo sync -c
| + | |
| − | </syntaxhighlight>
| + | |
| − | 同步过程中,由于网络原因出现中断,可以使用下面脚本同步代码:
| + | |
| − | <syntaxhighlight lang="bash">
| + | |
| − | #! /bin/bash
| + | |
| − | repo sync -c
| + | |
| − | while [ $? -ne 0 ];
| + | |
| − | do
| + | |
| − | repo sync -c
| + | |
| − | done
| + | |
| − | </syntaxhighlight>

可以通过使用TF卡启动eFlasher系统，将引导和系统分别安装到不同存储设备，但是由于CPU不支持直接从M.2和USB设备引导，所以虽然系统可以安装到M.2和USB设备，但是引导仍然需要安装到eMMC或者TF卡。
操作步骤如下：
You can use a TF card to boot the eFlasher system, allowing the boot and system to be installed on different storage devices. However, since the CPU doesn’t support booting directly from M.2 and USB devices, the system can be installed on M.2 and USB devices, but the boot must still be installed on eMMC or a TF card.
Steps are as follows:
