OpenADK - Open Source Appliance Development Kit

What is it?

A free construction kit for Embedded Devices. The resulting firmware boots up very fast, is updateable without losing local configuration changes and the root filesystem is mounted read-only. The default configuration creates a very small linux system. The default configuration for software packages and the system is secure by default.

What is it, too?

A great menu based system to create a toolchain for a lot of architectures and C library combinations. It supports Linux and bare-metal toolchains. The C libraries uClibc-ng, musl, GNU libc and newlib are supported. You can create toolchains for 46 different architectures. Support for AARCH64, Alpha, ARC, ARM, AVR32, Blackfin, C6X, CR16, CRIS, C-Sky, Epiphany, FR-V, FT32, H8/300, HPPA, IA64, KVX, LM32, Loongarch, M32C, M32R, M68K, METAG, Microblaze, MIPS, MIPS64, MN10300, Moxie, MSP430, NDS32, NIOS2, OR1K, PPC, PPC64, RISCV32, RISCV64, RX, S/390, SH, SPARC, SPARC64, Tile, V850, X86, X86_64 and Xtensa. You can use it on any computer running Linux, BSD, MacOS X or Windows (Cygwin) to create the toolchains.

Embedded Systems and more

There are only few samples for different embedded systems. The porting state of the different embedded devices in OpenADK may vary from fully supported to just builds. OpenADK is a framework to help you to create a firmware for your appliance. It might not be usable out-of-the box for the different samples provided.

There are samples for Raspberry PI 0/1/2/3/4/5, Solidrun Cubox-i/Hummingboard, Mikrotik Routerboard 532, PCEngines Wrap/Alix/APU, Atmel NGW100 / Grasshopper and Hitachi EDOSK-2674.

Samples for different kind of system emulators or simulators are included, too. There are samples for Qemu (different architectures), Synopsys NSIM, Aranym-M68K and GDB simulator.
