How to setup Raspberry Pi Zero W

1. Download OS image

Download Raspbian from the official site

2. Format a MicroSD card and Write OS image

The format must be MS-Dos. In terms of Mac, open “Disk Utility” and choose the MicroSD card and Erase the data. By the way, a MicroSD card, 8GB or larger.

$ diskutil list/dev/disk0 (internal, physical):
0: GUID_partition_scheme *121.3 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_CoreStorage Macintosh HD 120.5 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
/dev/disk1 (internal, virtual):
0: Apple_HFS Macintosh HD +120.1 GB disk1
Logical Volume on disk0s2
/dev/disk2 (internal, physical):
0: FDisk_partition_scheme *7.9 GB disk2
1: DOS_FAT_32 BOOT 7.9 GB disk2s1

In this case, my disk is disk2.

$ diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful

Then, move into the folder which has the OS image.

$ sudo dd bs=1m if=2017–09–07-raspbian-stretch-lite.img of=/dev/rdisk21768+1 records in
1768+1 records out
1854590976 bytes transferred in 367.071585 secs (5052396 bytes/sec)

It takes a few minutes.

№3 and 4 are options for people who don’t want to use a external monitor and a keyboard.

3. Create ssh file on the card

Of course, this need to plugin the SD card.

$ touch /Volumes/boot/ssh

4. Add a few lines to cmdline.txt

Add “modules-load=dwc2,g_ether” between rootwait and quiet.
More over add “dtoverlay=dwc2” to cmdline.txt

$ echo "dtoverlay=dwc2" >> /Volumes/boot/config.txt5. Turn on Raspberry Pi and connect to the Pi via ssh
Initial settings are followings.

User name: pi
Host name: raspberrypi
Password: raspberry

6. Update OS

$ sudo apt-get update
$ sudo apt-get upgrade

7. Add a new user and delete pi user(for security)
