树莓派食用指南
烧录
MacOS
查看当前已挂载的卷：
df -h
使用 diskutil unmount 将这些分区卸载：
diskutil unmount /dev/disk1s1
通过 diskutil list 来确认设备：
diskutil list
使用 dd 命令将系统镜像写入，需要特别特别注意 disk 后的数字，不能搞错！ （说明：/dev/disk1s1 是分区，/dev/disk1 是块设备，/dev/rdisk1 是原始字符设备）
dd bs=4m if=wheezy-raspbian.img of=/dev/rdisk1
用 diskutil unmountDisk 卸载设备：
diskutil unmountDisk /dev/disk1

sudo route add default gw 192.168.1.1
sudo ifconfig eth0 up
修改 /etc/network/interfaces
sudo vim /etc/network/interfaces
修改为：
auto lo
iface lo inet loopback
iface eth0 inet static

自定义分辨率
http://shumeipai.nxez.com/2013/08/31/custom-display-resolution-raspberry-pie.html
修改config.txt文件
- 修改 overscan 选项
# uncomment this if your display has a black border of unused pixels visible and your display can output without overscan
disable_overscan=1
- 修改屏幕分辨率
# uncomment to force a console size. By default it will be display's size minus
# overscan.
framebuffer_width=1280
framebuffer_height=1024
- 修改屏幕属性
hdmi_group=2 选择计算机显示器分辨率。hdmi_mode=35 选择屏幕分辨率和刷新屏幕。 hdmi_ignore_edid=0xa5000080 命令树莓派不检测 HDMI 设备的任何信息，按照指定的分辨率输出。
# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2
hdmi_mode=35
hdmi_ignore_edid=0xa5000080
