Setting for OTG mode for pi zero

Instruction

1. add the following text to /boot/config.txt

   # Enable OTG mode
   dtoverlay=dwc2
   

2. Save the config.txt file as plain text and then open up cmdline.txt After rootwait (the last word on the first line) add a space and then modules-load=dwc2,g_ether

3. Create an empty file named as ssh.txt in /boot

4. connect to your pi through ssh

   # default password is raspberry
   ssh pi@raspberrypi.local
   

5. Setup for locale, add following text in /etc/default/locale

   LC_CTYPE=en_US.UTF-8
   LC_ALL=en_US.UTF-8
   

6. Change password, Setup localization, interface option, network naming …

   • using command sudo raspi-config to setup raspberry pi zero.

7. Setup wifi sharing, copy the following code to /etc/network/interfaces

   auto lo usb0
   allow-hotplug usb0
   iface usb0 inet manual

8. Connect wifi without using sudo raspi-config command Since the /boot partition is accessible by any computer with an SD card reader, wifi configuration is now much simpler.

A typical wpa_supplicant.conf file is:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=«your_ISO-3166-1_two-letter_country_code»

network={
    ssid="«your_SSID»"
    psk="«your_PSK»"
    key_mgmt=WPA-PSK
}

Add ssh public key

• mkdir ~/.ssh & cd ~/.ssh & touch authorized_keys
• create authorized_keys file
• paste the ssh public key to authorized_keys (mostly the key store in ~/.ssh/id_rsa.pub )
