docker-emsys-nie

A Docker image containing binaries required for the Embedded Systems Lab (Sem 6) at NIE Mysuru

Why?

Convenient to have an image that has everything required for the lab without the hassle of getting build dependencies. (I had a miserable time setting mine up). Hope this helps you! 😄

Prerequisites

• OS: Linux-based (preferred). For Windows, try this (no guarantees, I haven't tested this. If you can help here, please do)
• docker
  • If you use an Ubuntu-based system, look here.
  • Also take a look at the post-installation steps here.

Get it

You can pull from DockerHub (preferred):

$ docker pull codepurble/docker-emsys-nie

NOTE: If the image is updated, just repeat this command to get the latest one. Watch this repository to check for updates.

OR

You can build the image yourself using:

$ git clone https://github.com/CodePurble/docker-emsys-nie.git
$ cd docker-emsys-nie
$ docker build -t "some name" .

Info

This image contains the following packages:

• build-essential
• u-boot-tools
• gcc-arm-none-eabi
• gcc-arm-linux-gnueabi
• gcc-arm-linux-gnueabihf
• libncurses-dev
• bc
• cpio

Usage

This container intends to supply just the build dependencies that are required for the labs (e.g. cross compilers, linkers, etc.). This image does not aim to contain things like U-boot images, kernel archives etc. So what you should do is download those in your host system, and mount it in the container as a shared volume (see the example below). Things like qemu are not supplied in this container. You will have to install them on the host system itself.

Example

$ cd <your-workdir>
$ docker run --rm -it -v $(pwd):/opt/ codepurble/docker-emsys-nie

Here, the directory you are in (in the terminal where you ran the command) is mounted at the location /opt/ within the container, as a shared folder. You can access everything in that shared folder from within the container.

So, if you want to compile a Linux kernel, you should:

• Download and extract the archive in your host system somewhere
• Mount that directory as a shared volume in the container
• Compile it in the container
• Use the built binaries in your host system (e.g. use them with qemu)

NOTE: In the above example, if you built the image yourself, the image name must be the one you gave

Contributions

I will try to keep this as up to date as possible. If there is something missing, submit a PR! If anyone can help to test and maintain on Windows, it will be great.

And, you know the drill, if there's a problem, open up an issue.
