Arm(R) Ethos(TM)-U core platform

Arm(R) Ethos(TM)-U core platform is provided as an example of how to produce a firmware binary for a given target platform. This software is primarily intended for guidance, to demonstrate how to boot up a firmware binary and how to run an inference on an Arm Ethos-U compatible platform.

This repository contains target specific files, like linker scripts. Target agnostic software components are provided in the core_software repository.

Targets

Arm(R) Corstone(TM)-300

The Arm(R) Corstone(TM)-300 is a reference design of how to to build a secure System on Chip (SoC). A fixed virtual platform (FVP) of the Arm Corstone-300 including the Arm Ethos-U can be downloaded from the Ecosystem page at developer.arm.com.

Building

Building with default settings requires CMake for the configuration and make for building. This will produce an elf file which can be run on the FVP.

$ cmake -B build/corstone-300 targets/corstone-300
$ cd build/corstone-300
$ make

It is also possible to build with a different toolchain.

$ cmake -B build/corstone-300 targets/corstone-300 -DCMAKE_TOOLCHAIN_FILE=$PWD/cmake/toolchain/arm-none-eabi-gcc.cmake
$ cd build/corstone-300
$ make

Please see README_WINDOWS.md for additional information regarding building on a Windows system.

Testing

Assuming that the Corstone-300 FVP has been downloaded, installed and placed in the PATH variable. Then the software binaries can be tested like this.

$ ctest

Individual applications can also be run directly with the FVP, for example like this.

$ FVP_Corstone_SSE-300_Ethos-U55 applications/freertos/freertos.elf
