Using Eclipse with its local Version of Java Virtual Machine

Posted on by
10

Eclipse is probably the most used and de-facto standard IDE for any development for ARM Cortex or any other devices. It is very easy these days to construct an unlimited and unrestricted IDE (see “Breathing with Oxygen: DIY ARM Cortex-M C/C++ IDE and Toolchain with Eclipse Oxygen“). Up to the point that I can pack it into a .zip file and pass it around e.g. in a class room environment, so no installer at all is needed with the exception of the debug probe USB drivers. As Eclipse is using a Java Virtual Machine (VM), it is a good idea to bundle the VM with the IDE, and this article is about how to do this.

In “EmbSysRegView 0.2.6 for Eclipse Neon and Oxygen” I have described how to add CMSIS-SVD register detail files to Eclipse using the EmbSysRegView plugin.

But what I need to add vendor or any other SVD files to it? Here is how:

Building Eclipse and MCUXpresso IDE Projects from the Command Line

Eclipse as IDE takes care about compiling and building all my source files. But in an automated build system I would like to build it from the command line too. While using make files (see “Tutorial: Makefile Projects with Eclipse“) is an option, there is another easy way to build Eclipse projects from the command line:

Breathing with Oxygen: DIY ARM Cortex-M C/C++ IDE and Toolchain with Eclipse Oxygen

Posted on by

Last month (June 2017), the latest version of Eclipse “Oxygen” has been released, and I have successfully used it in several embedded projects. Time to write a tutorial how to use it to build a custom Do-It-Yourself IDE for ARM Cortex-M development: simple, easy, unlimited and free of charge. While the DIY approach takes a few minutes more to install, it has the advantage that I have full control and I actually know what I have.

Troubleshooting Tips for FreeRTOS Thread Aware Debugging in Eclipse

Posted on by

FreeRTOS seems to get more and more popular, and I think as well because more and more debugger and Eclipse IDE vendors add dedicated debugging support for it.

How to use Custom Library Names with GNU Linker and Eclipse

Posted on by

By default, the GNU Linker expects a very special naming scheme for the libraries: the library name has to be surrounded by “lib” and the “.a” extension:

lib<NAME>.a

But what if the library I want to use does not conform to that naming standard?

Tutorial: Makefile Projects with Eclipse

Posted on by

The benefit of an IDE like Eclipse is: it makes working with projects very easy, as generates make files and it takes and automatically manages the make file(s). But sometimes this might not be what I want because I need greater flexibility and control, or I want to use the same make files for my continues integration and automated testing system. In that case a hand crafted make file is the way to go.

One thing does not exclude the other: This article explains how to use make files with Eclipse with similar comfort as the managed build system in Eclipse, but with the unlimited power of make files:

Getting Started: ROM Bootloader on the NXP FRDM-KL03Z Board

Posted on by

A bootloader on a microcontroller is a very useful thing. It allows me to update the firmware in the field if necessary. There are many ways to use and make a bootloader (see “Serial Bootloader for the Freedom Board with Processor Expert“). But such a bootloader needs some space in FLASH, plus it needs to be programmed first on a blank device, so a JTAG programmer is needed. That’s why vendors have started including a ROM bootloader into their devices: the microcontroller comes out of the factory with a bootloader in FLASH. So instead writing my bootloader, I can use the one in the ROM.

And as with everything, there are pros and cons of that approach.
