IoT Core NXP BSP Repository Support Notice

This repository is no longer supported and is now read-only. The BSP and documentation for the iMX6, iMX7 and iMX8 processors for Windows 10 IoT is now published by NXP here. Support for the BSP is available in NXP's community forums.

The following repositories have been archived and made read-only on GitHub. If you have a fork of any of these repositories they will remain active, but no new updates will be supplied by Microsoft. Development has stopped in these repositories and all future work will be released by NXP in their BSP.

The repositories to be archived are: https://github.com/ms-iot/imx-iotcore https://github.com/ms-iot/u-boot https://github.com/ms-iot/edk2 https://github.com/ms-iot/imx-edk2-platforms https://github.com/ms-iot/mu_platform_nxp https://github.com/ms-iot/mu_silicon_nxp

The NXP BSP only has board support for NXP EVK and Sabre devices. For other previously supported devices, contact the manufacturer for further support.

All trusted application binaries in this repository have been removed. The sources in this repository can still be built, but to generate a usable image, the trusted application firmware must be manually built and added according to the instructions on the NXP website.

About

This document provides a brief introduction to Project MU as well as information about building a UEFI image for the iMX8. There's more to booting an iMX8 than UEFI; additional documentation for those steps is provided here.

Building with MU TL;DR

  1. Run git submodule update --init --recursive to check out all the submodules.
  2. Run python {Platform}/{Device}/PlatformBuild.py --setup to set up the build environment. Includes fetching Nuget dependencies and synchronizing submodules.
  3. Run python {Platform}/{Device}/PlatformBuild.py to invoke the build process.

MU Repos

NXP Platform

This is platform repo, which is the root repository in which all the other submodules are located. This is also where code specific to the platform or devices would be located, including PlatformBuild.py and PlatformBuildWorker.py.

Silicon/ARM/NXP

Silicon code provided from a manufacturer is kept in its own submodule so it can be maintained seperately from platform code.

MU_BASECORE

This is the main repo. Contains the guts of the build system as well as core UEFI code, forked from TianoCore.

Silicon/ARM/MU_TIANO

Silicon code from TianoCore has been broken out into indivudal submodules. iMX8 is ARM, so we need this submodule. An Intel project would include Intel/MU_TIANO.

Common/MU_TIANO

Additional, optional libraries and tools forked from TianoCore.

Common/MU

Additional, optional libraries and tools we've added to make MU great!

Common/MU_OEM_SAMPLE

This module is a sample implementation of a FrontPage and several BDS support libraries. This module is intended to be forked and customized.

Build Environment

Part of Project Mu is moving towards a fully Python build environment. We currently have three published Python modules, using pip, that encompass setting up the build environment, logging, and running CI builds.

Documentation of the build system is still in progress on the Project MU page under Code Repositories.

Pip modules

mu_python_library

Python files describing miscellaneous components (EDKII, TPM, etc.)

mu_environment

This is the code that PlatformBuild.py calls in to that sets up the build environment.

mu_build

Command line interface that fetches dependencies and builds each module specified by a descriptor file. See MU_BASECORE as an example.

Troubleshooting

To forcibly install the latest version of mu_environment: pip install --upgrade mu_environment --force-reinstall --no-cache-dir

Since mu_environment has a dependency on mu_python_library, it should be updated through this command as well. If they are not, the same command can be run for mu_python_library.

Setup Info for iMX8

  • sudo apt-get install gcc g++ make python3 python3-pip git mono-devel
    • Minimum Python version is 3.6
    • Minimum git version 2.11
  • git clone https://github.com/ms-iot/MU_PLATFORM_NXP
  • Install pip modules for build:
    • pip3 install -r requirements.txt --upgrade
  • Change into the directory you just cloned and run:
    • git submodule update --init --recursive
  • Download Linaro AARCH 64 GCC 7.2.1
    • Set GCC5_AARCH64_PREFIX to this path
      • tar -xf gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu.tar.gz
      • export GCC5_AARCH64_PREFIX=$PWD/gcc-linaro-7.2.1-2017.11-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
  • python3 NXP/MCIMX8M_EVK_4GB/PlatformBuild.py --setup
    • This fetches any dependencies via NuGet and synchronizes submodules
  • rm -r Build; rm -r Conf; python3 NXP/MCIMX8M_EVK_4GB/PlatformBuild.py TOOL_CHAIN_TAG=GCC5 BUILDREPORTING=TRUE BUILDREPORT_TYPES="PCD"
    • Removing Build and Conf directories ensures that you aren't accidentally keeping around configuration files and autogen build files that need to be updated.
    • Specify the TOOL_CHAIN_TAG either here or in NXP/Conf/Target.template.ms
    • Build reports are placed in the Build folder on a successful build and contain a complete list of every module that was built and what the PCDs were set to.
  • Serial output
