The original article was first posted back in 2013. Since posting I have been contacted many times regarding the article. One re-occuring question has been “How do I do this using GCC?”. So I thought it was about time I updated the article using GCC.
GNU Tools for ARM Embedded Processors
The original article used the Keil toolchain, here I am using arm-none-eabi-gcc. One of the major benefits of CMSIS is that almost all the code from the original posting will compile […]

In Part 3 we managed to build a Docker image containing the tools required to compile and link C/C++ code destined for our embedded Arm target system. However, we’ve paid little attention to the size of the image. Doing a quick Docker image listing we can see its grown to a whopping 2.14GB:
$ docker image ls

In the previous posting we looked at defining a custom Dockerfile where we can add specific tools (and their dependencies). From that we created a Docker image and this allowed us to build C/C++ code in a Docker container, ensuring a consistent build environment.
So far we have to build all our code using the native GCC toolchain which is part of the base Docker image (gcc:7.2). However, I want to be able to build an image I can download and run […]
