pi-init

Purpose

A program which lets you set up a Raspberry Pi solely by writing to the /boot partition (i.e. the one you can write from most computers!)

This variant is specific for Emlid's Navio2 project, derived from https://github.com/BytemarkHosting/pi-init2/, and which I use for rapidly wiping and re-flashing development drones in the US.

It currently takes care of:

• Keyboard layout and locale
• Framebuffer size (in case you're piping video through the PI and out through a VTX)
• Updating at boot
• Enabling arducopter and configuring it to listen on the address and TTY set in setup_vars.sh
• Timezone
• Expanding the root filesystem
• Rebooting on completion of the above

Usage

From your desktop / laptop:

• Download and write a standard Emlid Raspbian image
• Unzip the latest release into the /boot partition
• Configure appliance/etc/wpa_supplicant/wpa_supplicant.conf for your network (if using a WiFi connection)
• Configure setup_vars.sh in the /boot partition to fit your needs for locale, time zone, arducopter settings, etc.
• Remove the SD card and put it into your Pi.

The Raspberry Pi should now boot into a headless system configured for arducopter. The first boot takes a few minutes depending on your network, and which model of Raspberry Pi you use (I tested with a model B).

You can edit these files:

• appliance/etc/wpa_supplicant/wpa_supplicant.conf - for wireless network credentials, if you're using a wireless adapter.

Building pi-init

I've included a script called 'build-and-copy' which I use from an Ubuntu system to build the pi-init2 program and create a zipfile to copy to the SD card boot partition. Any contributions appreciated.

A ssh flag file is also included to enable ssh within Jessie Lite.
