This article will help you get setup if you have a M1 with a solution using Docker Desktop.

\uD83D\uDCD8 Instructions for Docker Setup

This guide will provide instructions for getting a virtual environment setup with Docker which will allow you to simulate your code in a Linux environment

  1. Download Docker Desktop for Apple Silicon (https://www.docker.com/products/docker-desktop/ )

  2. Install the latest version of vagrant (https://www.vagrantup.com/downloads )

    1. For M1s, you can use brew or you can download the ARM64 version

  3. Clone the repo: git clone https://github.com/uw-midsun/box.git

  4. Go to your box directory and switch to master branch

    1. You can check if you are on the master branch if you run git branch

      ~ % cd box 
box % git checkout master

  5. Before running vagrant up , make sure that you have docker open

  6. Run vagrant up --provider=docker

  7. Run vagrant ssh

  8. Run cd shared

  9. Run git clone https://github.com/uw-midsun/fwxv.git && cd fwxv (if you clone with https, you will need to set up an ssh key later which is covered in our setup page)

  10. Run scons sim --project=leds --platform=x86 to test that your environment is working correctly. If it compiles and runs your environment is set up. Correct output will be constant printing of “blink.”

👾 Guide to flashing on M1s

Only follow these instructions if you have already finished the instructions below and are ready to flash

While this guide provides instructions for flashing, it's important to note that the execution of scons sim still remains necessary within the Docker environment

  1. Ensure you are not in the linux environment (Docker environment)

  2. Go to the box repository and start up your python virtual environment by running source venv/bin/activate

  3. Try running arm-none-eabi-gcc --version and look for output. If it says that it cannot find arm-none-eabi-gcc then run source ~/.zshrc

    1. If it still doesn’t work, please contact a lead for help

  4. Make the necessary connections you need with the hardware

  5. cd shared/fwxv then run scons flash --project=[project name] (If you need some other scons command please reference the build_system.md file)

✨ Guide to setting up dependencies for flashing on M1s

Ensure that these steps, including any future flashing activities, are performed outside the Linux/Docker environment

  1. Install package dependencies:

    1. Run this shell script in box directory:

      1. This uses virtualenv, a python package manager. (https://docs.python.org/3/library/venv.html )

  2. Install arm-none-eabi-gcc compiler

    1. Download gcc-arm-none-eabi version 9.2.1 which is obtained from https://developer.arm.com/downloads/-/gnu-rm

    2. Move your tar file into your box folder and change current directory to box directory

    3. Run this code in the box repository:

    4. Run scons in the box/shared/fwxv folder to test if building works

      For people who care about the step-by-step of the m1.sh: 

      // Should be in the box repository with .tar.bz2 file
tar xzf gcc-arm-none-eabi-9-2019-q4-major-mac.tar.bz2

// move into gcc-arm-none-eabi folder
cd gcc-arm-none-eabi-9-2019-q4-major/bin

// run pwd and copy output into next command
pwd

// enter pwd output in [pwd input here] (do not include [] braces)
// ex. echo 'export PATH="/Users/your-user-name/box/gcc-arm-none-eabi-9-2019-q4-major/bin:$PATH"' >> ~/.zshrc
echo 'export PATH="[pwd input here]:$PATH"' >> ~/.zshrc
source ~/.zshrc

// you may get a permissions issue so we will "unquarantine" (remove quarantine attribute) our files
// path to gcc-arm-none-eabi folder can be grabbed by cd gcc-arm-none-eabi-9-2019-q4-major and pwd
// ex. xattr -d -r com.apple.quarantine /Users/your-user-name/box/gcc-arm-none-eabi-9-2019-q4-major/
xattr -d -r com.apple.quarantine [path to gcc-arm-none-eabi folder]

// check arm-none-eabi-gcc version 
// Should get output similar to: 
/* 
*  arm-none-eabi-gcc (GNU Tools for Arm Embedded Processors 9-2019-q4-major) 9.2.1 20191025 (release) [ARM/arm-9-branch revision 277599]

// To test if it works, run scons to see if everything compiles correctly for you
