==在eMMC上安装Arch Linux==

参考了<ref name="arch">[https://archlinuxarm.org/platforms/armv7/ti/beaglebone-black archlinuxarm.org]</ref>和<ref>[http://www.pataphysical.info/installing-arch-linux-on-the-beaglebone-black.html pataphysical.info]</ref>

===制作Arch Linux SD卡===

在自己电脑（Kubuntu 16.04）上：

 <nowiki>
# dd if=/dev/zero of=/dev/sdb bs=1M count=8
# fdisk /dev/sdb #
# mkfs.ext4 /dev/sdb1
# mkdir mnt
# mount /dev/sdb1 mnt
# wget http://os.archlinuxarm.org/os/ArchLinuxARM-am33x-latest.tar.gz
# bsdtar -xpf ArchLinuxARM-am33x-latest.tar.gz -C mnt
# sync
# dd if=mnt/boot/MLO of=/dev/sdb count=1 seek=1 conv=notrunc bs=128k
# dd if=mnt/boot/u-boot.img of=/dev/sdb count=2 seek=1 conv=notrunc bs=384k
# umount mnt
# sync</nowiki>

用SD卡启动BBB。

===在eMMC中安装Arch Linux===

进入BBB终端。若需要用串口终端，串口在J1上，pinout为：
# GND
# NC
# NC
# B_UART0_RX
# B_UART0_TX
# NC

在<code>/dev/mmcblk1</code>上重复刚才的操作：

 <nowiki>
# dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=8
# fdisk /dev/mmcblk1 #
# mkfs.ext4 -O ^metadata_csum,^64bit /dev/mmcblk1p1
# mkdir mnt
# mount /dev/mmcblk1p1 mnt
# pacman -S wget
# wget http://os.archlinuxarm.org/os/ArchLinuxARM-am33x-latest.tar.gz
# bsdtar -xpf ArchLinuxARM-am33x-latest.tar.gz -C mnt
# sync
# dd if=mnt/boot/MLO of=/dev/mmcblk1 count=1 seek=1 conv=notrunc bs=128k
# dd if=mnt/boot/u-boot.img of=/dev/mmcblk1 count=2 seek=1 conv=notrunc bs=384k
# umount mnt
# sync
# poweroff</nowiki>

拔出SD卡开机。

===安装必需软件包===

 <nowiki>
# pacman -S sudo vim fish python </nowiki>

用<code>visudo</code>启用wheel组的sudo权限。

====OpenVPN====

安装OpenVPN时报404，编辑<code>/etc/pacman.d/mirrorlist</code>使用台湾的镜像，成功安装。

将配置文件放在<code>/etc/openvpn/client/skyworks.conf</code>，运行<code>systemctl enable openvpn-client@skyworks.service</code>启用之。
