Development Environment installation


DEM can install preconfigured Development Environments from online catalogs. List the available catalogs:

dem list-cat


You can add or delete catalogs with the dem add-cat and dem del-cat commands.

After a clean installation, you have the axem organization enabled by default. You can list the available Development Environments in all available catalogs:

dem list --all --env

For this tutorial, we are going to use the Tutorial Development Environment. You can get more information about it by the following command:

dem info Tutorial

One of DEM's biggest advantages is that installing a preconfigured Development Environment is only a single command. Install the Tutorial Development Environment:

dem pull Tutorial

The DEM will pull the images we saw after the dem info Tutorial command:

  • axemsolutions/make_gnu_arm:latest: contains the make and gnu-arm-none-eabi tools
  • axemsolutions/stlink_org:latest: contains the stlink-org tool
  • axemsolutions/cpputest:latest: contains the CppUTest tool


The images get pulled from an available registry. List the available registries with the dem list-reg command. Use the dem add-reg and dem del-reg commands to add and delete registries.

If you issue the dem info Tutorial command again, you will see that the required images are now available locally. Running dem list --local --env makes the locally installed Development Environments get listed, so in our case, you should see the Tutorial Development Environment.

Now you are ready to make embedded software!


At this point, you can use the tools as containerized CLI applications.
