ARM SDK

OS development toolkit for various ARM embedded devices

Introduction

ARM SDK is a build system used to toast OS images for ARM devices. Currently only Devuan is supported, but later on support for other distros will be added.

Requirements

This SDK is designed to be used interactively from a terminal as well from shell scripts.

For a Debian-based OS, install the following packages:

gnupg2 debootstrap curl rsync gcc-arm-none-eabi parted kpartx qemu-user-static sudo git-core parted gcc-multilib lib32z1 u-boot-tools device-tree-compiler cgpt xz-utils lzop

On any other, find the equivalents of the aforementioned packages.

Quick start

; git clone https://github.com/dyne/arm-sdk.git
# OR
; git clone https://git.devuan.org/devuan/arm-sdk.git

If you have cloned the repository before, please do a git pull in order to update to the latest versions. Your experience will be better.

Edit the config file to match your crosscompile toolchain. Consult arm/README.md if you're in a need of a precompiled one, then run zsh. In case you have conflicting extensions on your zsh configuration, safest way would be to run a vanilla one, using:

; zsh -f

then step inside the sdk, "source" it:

; cd arm-sdk && source sdk

Now is the time you choose the device and OS you want to build the image for. Currently you can choose between these distros:

• devuan

and one of the following devices:

• raspi2 - Raspberry Pi 2 and 3
• bananapi - Banana Pi
• bananapro - Banana Pi Pro
• cubieboard2 - Cubieboard 2
• cubietruck - Cubietruck
• chromeacer - Acer ARM Chromebook
• odroidxu - ODROID-XU
• bbb- BeagleBone Black

; init devuan raspi2

Once initialized, you will get further instructions.

For more info, please consult the README included in the arm subdirectory.

After the image is built, you will find it compressed, along with its sha256 sum in the arm/finished/ directory. The default root password is devuan and SSH with permitted root login is enabled on startup, along with DHCP to get you up and running headless if you require it.

Configuration

Edit the config file included in the root directory of arm-sdk to your liking. If you are using a custom toolchain, add it to the PATH as described.

Notes and quirks for specific devices

ODROID-XU

• The kernel refuses to build with Devuan's default toolchain arm-none-eabi. Use arm-linux-gnueabi-4.7 that I provide on https://pub.parazyd.cf/mirror instead.

Raspberry Pi 2

• This build script will create an image that works on the Raspberry Pi 3 as well. It also includes the required firmware for getting onboard Wifi/Bluetooth working.

Acer Chromebook

• The Chromebook I tested this image on names the wireless interface mlan0, so please keep note of it when you try connecting to an access point.

BeagleBone Black

• The kernel refuses to build with Devuan's default toolchain arm-none-eabi. Use arm-linux-gnueabi-4.7 that I provide on https://pub.parazyd.cf/mirror instead.
• In /root/ you will find the xorg.conf needed to run X properly. You will also find a shell script that allows you to use USB as an ethernet device

The Devuan SDK was conceived during a period of residency at the Schumacher college in Dartington UK, greatly inspired by the laborious and mindful atmosphere of its wonderful premises.
