| |
| − | ===烧录第一个Linux镜像到 R2===
| |
| − | 1.你可以从下面链接下载最近的镜像
| |
| − | * Here is the example image link: http://forum.banana-pi.org/t/bpi-r2-new-image-release-ubuntu-16-04-v1-3-2018-3-30/5293
| |
| − |
| |
| − | 2.在你的Ubuntu系统电脑上安装bpi-tools, 执行以下命令即可安装：
| |
| − | * apt-get install pv
| |
| − | * curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
| |
| − |
| |
| − | 3.下载完镜像后, 插入TF卡到你的Ubuntu电脑中
| |
| − | * 运行命令 "bpi-copy xxx.img /dev/sdx" 烧录镜像到你的TF卡中.
| |
| − |
| |
| − | 4.完成步骤3后, 请将TF卡插入R2, 长按电源键10s直到启动R2
| |
| − |
| |
| − | ====在SD卡上安装Ubuntu====
| |
| − | 1. 从Github上复制bsp代码
| |
| − | | |
| − |
| |
| − | 2. 执行"./build.sh"命令, 编译你自己的uboot和 kernel.
| |
| − | [[Image:R2_build_sh.png]]
| |
| − |
| |
| − | 3. 完成编译后, 执行"cd SD"命令, 插入TF卡到你的PC端 .
| |
| − |
| |
| − | 4. 执行命令 "bpi-update -c bpi-r2.conf -d /dev/sdX", 将编译好的kernel更新到你的TF卡中.
| |
| − |
| |
| − | ====在emmc上安装Ubuntu====
| |
| − | 1. 如果你想在emmc上安装ubuntu, 请遵循以下这些步骤：
| |
| − |
| |
| − | bpi-copy <XXX.img.zip> /dev/mmcblk1
| |
| − |
| |
| − | * XXX.img.zip 是我们下载的Ubuntu镜像, 请从 http://www.banana-pi.org/r2-download.html 下载
| |
| − | * 关机
| |
| − | * 移除SD卡并开机
| |
| − |
| |
| − | ====如何安装在SD&emmc上安装Openwrt====
| |
| − | 1. 从Github上复制OpenWrt代码.
| |
| − | * 执行命令 "git clone https://github.com/garywangcn/bpi-r2_lede.git"
| |
| − |
| |
| − | 2. 你需要安装 gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers.
| |
| − |
| |
| − | 3. 运行"./scripts/feeds update -a"命令，分别获取定义在“feeds.conf / feeds.conf.default”和"./scripts/feeds install -a"中的最新的软件包定义， 然后安装它们的所有符号链接到 package/feeds/.
| |
| − |
| |
| − | 4. 使用 "make menuconfig"命令来配置你的镜像.
| |
| − | * 选择 "Target System" 来配置 "MediaTek Ralink ARM"
| |
| − | * 选择 "Boot Loaders" 来配置 "u-boot-bpi_r2"
| |
| − |
| |
| − | 5. 执行"make -j1 V=s" 命令来编译你自己的OpenWrt镜像.
| |
| − |
| |
| − | 6. 编译完成后，你可以通过两种方法安装镜像.
| |
| − | (1) 将TF卡插到Ubuntu PC端, 并输入 "build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/",
| |
| − | 你会发现两个镜像：
| |
| − | * mtk-bpi-r2-EMMC.img
| |
| − | * mtk-bpi-r2-SD.img
| |
| − | (2) 烧录镜像到TF卡，执行 "dd if=mtk-bpi-r2-SD.img of=/dev/sdX"命令
| |
| − |
| |
| − | (3) 如果你想要安装镜像到emmc,请遵循以下步骤：
| |
| − | * 从SD卡启动R2
| |
| − | * 复制EMMC镜像到SD卡运行的镜像中
| |
| − | * 解锁EMMC boot0 block: echo 0 > /sys/block/mmcblk0boot0/force_ro
| |
| − | * 烧录EMMC镜像到EMMC的用户数据区: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0 (assume /dev/mmcblk0 is for EMMC)
| |
| − | * 烧录 preloader 到 EMMC boot0 分区: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0boot0 bs=1M count=1
| |
| − | * 更改EMMC的分区配置为48h: 重启SD卡的运行系统, 并输入U-boot命令行，运行命令“emmc pconf 48” (对于此步骤，我们可以使用mmc-utils更改用户空间中的分区配置，请参阅BPI-R2 OpenWrt（LEDE）中源代码获取更多信息：2018-04-11)
| |
| − | * 关机，移除SD卡，然后重启R2板
| |
| − |
| |
| − | 7. 此步骤用于升级，如果你构建完成后不想安装镜像，你可以直接运行升级.
| |
| − | * 拷贝 "bin/targets/mediatek/32/lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar" to 到正在运行OpenWrt系统的R2板中(无论是从emmc还是SD卡运行的), 然后运行 "sysupgrade lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar" 命令进行 kernel和 rootfs的升级.
