Building Phoenix-RTOS image

To create Phoenix-RTOS image for selected target the phoenix-rtos-project repository should be used. This repository aggregates all operating system modules - kernel, standard library, device drivers, filesystems, utilities and loader.

This chapter contains instruction how to build reference project and how to create the final system image.

Obtaining the sources

The first step of preparation of the final system image is the repository cloning. The repository should be cloned and recursively (to get the submodules):

git clone --recursive https://github.com/phoenix-rtos/phoenix-rtos-project.git

Supported target platforms

The reference Phoenix-RTOS project supports following target platforms:

  • armv7m4-stm32l4x6
  • armv7m7-imxrt105x
  • armv7m7-imxrt106x
  • armv7m7-imxrt117x
  • armv7a7-imx6ull
  • ia32-generic
  • riscv64-spike
  • riscv64-virt

To get the list of valid targets the build.sh script should be launched with empty TARGET variable , eg:

$ ./phoenix-rtos-build/build.sh
TARGET variable not set
Please specify a valid traget by setting TARGET variable to one of:
armv7a7-imx6ull
armv7m4-stm32l4x6
armv7m7-imxrt105x
armv7m7-imxrt106x
ia32-generic
riscv64-spike
riscv64-virt

Building using docker

This is the quickest way to start development - all necessary tools are distributed in docker image.

To build - provide a TARGET via ENV variable:

cd phoenix-rtos-project/
TARGET=ia32-generic ./docker-build.sh clean all

After the build successfully completes, kernel and disk images will be created and placed in the _boot directory.

Building using native toolchain

This is the method preferred when you plan to develop Phoenix-RTOS.

Firstly, you need to compile the toolchains for all required target architectures:

cd phoenix-rtos-project
(cd phoenix-rtos-build/toolchain/ && ./build-toolchain.sh i386-pc-phoenix ~/toolchains/i386-pc-phoenix)
(cd phoenix-rtos-build/toolchain/ && ./build-toolchain.sh arm-phoenix ~/toolchains/arm-phoenix)
(cd phoenix-rtos-build/toolchain/ && ./build-toolchain.sh riscv64-phoenix ~/toolchains/riscv64-phoenix)

Toolchain binaries should be added to PATH variable:

export PATH=$PATH:~/toolchains/i386-pc-phoenix/i386-pc-phoenix/bin/
export PATH=$PATH:~/toolchains/arm-phoenix/arm-phoenix/bin/
export PATH=$PATH:~/toolchains/riscv64-phoenix/riscv64-phoenix/bin/

To build a project - provide a TARGET via ENV variable:

TARGET=ia32-generic ./phoenix-rtos-build/build.sh clean all

After the build successfully completes, kernel and disk images will be created and placed in the _boot directory.

Launching Phoenix-RTOS

To start the created image on target architecture please see phoenix-rtos-doc/quickstart guide.
