Dangling pointers and memory corruption problems are nasty issues for any developer, and usually hard to find and locate in the code. Luckily Google has developed an open source tool to solve such issues: the Address Sanitizer (ASAN). The tool is available for x86 and other desktop style architectures, including Android and Linux. This article describes how ASAN can be used for an embedded target, e.g. ARM Cortex-M4 or similar.
Managed linker scripts are great on one side: the simplify the otherwise complex GNU linker script handling. On the other side it requires knowledge how to tweak them in case ‘non-standard’ behavior is needed.
If a Cortex microcontroller is unresponsive to a debug connection for various reasons, then this trick might help to recover that device for you. All you need is a debug probe from PEMICRO and a utility.
This is the third part in a series to get up and running using the Microsoft Visual Studio Code for embedded development on ARM Cortex-M. So far we have installed the needed tools, created a project and are able to build it from the command line. Now it is about how execute directly scripts or the build from the IDE.
This is the second part of series or articles how to use the Microsoft Visual Studio Code for embedded development on ARM Cortex-M. In this part I’m going to show how to create and build a project using CMake running Make or Ninja as build system.
As time flies by, my projects are evolving. My lab projects get used over multiple semesters, and the MCUXpresso projects by default use the SDK version used at that time.
This is great because I do want to have control over what SDK is used. But from time to time it makes sense to upgrade a project to a newer version. In this post I’ll show how an existing project can be upgraded to use a new SDK.
