How to build the rusEFI firmware from the source files

The following process is a step-by-step guide to creating the build environment in windows 10+ using Windows Shell for Linux

The best way to build the rusEFI firmware is using a set of tools that run best under linux,

  1. Install WSL Run the following in an elevated powershell

    Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

  2. Download linux
    Download the appx for linux 2004 from here: WSL Install Manual
    Or type the following into powershell:

    cd ubuntu/  
Invoke-WebRequest -Uri <https://aka.ms/wsl-ubuntu-2004> -OutFile Ubuntu.appx -UseBasicParsing

    This command will download the file to the currently active directory.

  3. install linux

    PS C:\Windows\system32> cd c:/Ubuntu  
PS C:\Ubuntu> Add-AppxPackage Ubuntu_2004.2020.424.0_x64.appx

    Open start menu and launch linux
    Wait for it to complete install and ask for username and password

  4. check WSL default install In powershell type:

    wslconfig /l

    Make sure the ubuntu 2004 is marked as default.

  5. get git

    sudo apt-get install git

  6. clone git

    git clone <https://github.com/YOUR-REPOSITORY/rusefi.git>

  7. Run setup script

    cd /home/owner/rusefi/firmware  
sh setup_linux_environment.sh

  8. install VScode in windows
    Download and install as normal, is should detect WSL and ask to install the extension for it, do this and close VScode

  9. Install VScode in linux

    cd /home/owner/rusefi  
code .

  10. Hit ctrl-b and run "build unit tests" Allow to run and complete, it may exit with "multiple targets" error, if so just run it a second time.

  11. exit both VScode and ubunu
    Click the x in VScode and type exit in ubuntu

  12. reboot ubuntu from the start menu and run make

    cd /home/owner/rusefi/firmware  
make

    This should build the firmware

  13. If successful then reopen VScode in ubuntu

    cd /home/owner/rusefi  
code .

  14. Run the built tool for the specific board in VScode
    Ctrl-Shift-B and select the chosen board, this should build the firmware.

  • Note submodules are their own thing - the main repo just contains a pointer to where the submodule should be checked out

  • Zach method:

install wsl (already have ubuntu 20.04 on wsl2)

sudo apt update  
sudo apt install openjdk-8-jre-headless -y  
curl -O <https://armkeil.blob.core.windows.net/developer/Files/downloads/gnu-rm/9-2020q2/gcc-arm-none-eabi-9-2020-q2-update-x86_64-linux.tar.bz2>  
tar -xf gcc-arm-none-eabi-9-2020-q2-update-x86_64-linux.tar.bz2

Without WSL

Less fancy toolchain without WSL works as well https://rusefi.com/forum/viewtopic.php?f=5&t=9
