Overview

Data & Controls

For D&C, we are going to be using a central docker container for all projects just to try and make development a bit easier. This docker container is specialized for embedded development to replace the awful and bloated embedded tools and IDE’s we would otherwise have to work with (*cough cough STM32 Microchip TI cough cough*).

Installation

1. Install docker

2. Create a Docker account and sign in locally

3. If Windows follow two more steps because Docker for Windows runs on WSL (Windows Subsystem for Linux):

   1. Update WSL by running wsl --update

   2. Set the default WSL version to 2 by running wsl --set-default-version 2

   3. Install the Ubuntu WSL distro by running wsl --install

   4. If you want to install a different distribution, I think you can set flags but Ubuntu is easier imo

   5. Running exit will get you out of WSL if you are in the distro

Usage

MacOS

1. Make sure Docker Desktop is started

2. Pull down the Docker container you are using by running docker pull <CONTAINER_NAME> where CONTAINER_NAME can be nwdepatie/ner-gcc-arm for microcontroller development

3. Start the container by running docker run --rm -it --privileged -v "$PWD:/home/app" <CONTAINER_NAME>:latest bash using the same container you just pulled.

   1. Make sure you are running it in whatever directory you want to operate on

4. Any flashing hardware should be mounted to container automatically

Linux

1. Make sure Docker is started (I just run docker and it works but results may vary)

2. Pull down the Docker container you are using by running docker pull <CONTAINER_NAME> where CONTAINER_NAME can be nwdepatie/ner-gcc-arm for microcontroller development

3. Start the container by running sudo docker run --rm -it --privileged -v "$PWD:/home/app" <CONTAINER_NAME>:latest bash using the same container you just pulled.

   1. Make sure you are running it in whatever directory you want to operate on

4. Any flashing hardware should be mounted onto container automatically

Windows

1. Make sure Docker Desktop is started

2. Pull down the Docker container you are using by running docker pull <CONTAINER_NAME> where CONTAINER_NAME can be nwdepatie/ner-gcc-arm for microcontroller development

3. Start the container by running docker run --rm -it --privileged -v "$(PWD):/home/app" <CONTAINER_NAME>:latest bash using the same container you just pulled.

   1. Make sure you are running it in whatever directory you want to operate on

   2. If the above command doesn’t work, try docker run --rm -it --privileged -v "%cd%:/home/app" <CONTAINER_NAME>:latest bash

4. To mount any flashing hardware (this may be condensed into a script in the future):

   1. Open a Windows terminal with admin privileges and run winget install usbipd

   2. Open a WSL terminal (wsl -d ubuntu) and run the following commands to enable mounting Windows USB devices in the Docker container

      1. sudo apt update

      2. sudo apt install linux-tools-virtual hwdata

      3. sudo update-alternatives --install /usr/local/bin/usbip usbip `ls /usr/lib/linux-tools/*/usbip | tail -n1` 20

   3. Start Docker container by running docker run --rm -it --privileged -v "$(PWD):/home/app" <CONTAINER_NAME>:latest bash replacing CONTAINER_NAME with the container name in one terminal

   4. (If interacting with hardware) Mount the Raspberry Pi probe by finding the device in another Windows terminal with usbipd wsl list and mount the device in a Windows terminal window (with admin privileges the first time you do this) with usbipd wsl attach --distribution=ubuntu --busid=<BUSID>

      1. You’re looking for the CMSIS-DAP v2 Interface device

         

Tools / Utils

# to build project
make all
