Reduce Eclipse ‘Install New Software’ Installation Time

Posted on by

In Eclipse, the usual way to add new plugins or extend the IDE is using the menu Help > Install New Software. Same thing for the newly released Freescale Kinetis Design Studio V3.0.0: I add the support for new devices in the Freescale Kinetis SDK from the SDK Eclipse update:

Installing Kinetis SDK v1.2 update in Eclipse

Installing Kinetis SDK v1.2 update in Eclipse

One thing I noticed with this (and all others updates I do) is that they take much time to install. That’s expected if the update needs to be downloaded from the web. But I was wondering why it takes so long even if the files are local?

Thanks to a tip (thank you, Marek!), there is a setting to cut the installation time :-). Continue reading →

Editing Compiler Include (or other) Settings in Eclipse

So now I have carefully set up my compiler include paths in Eclipse to tell the GNU compiler where to find my header files:

The question is: how can I apply these settings to another project?

CRC Checksum Generation with ‘SRecord’ Tools for GNU and Eclipse

Posted on by

One of the things missing for Embedded in the GNU linker is that it cannot generate a CRC checksum. Luckily, there is the solution of using SRecord:

Semihosting with GNU ARM Embedded (Launchpad) and Kinetis Design Studio

A while back I wrote two articles about Semihosting: “Semihosting with GNU ARM Embedded (LaunchPad) and GNU ARM Eclipse Debug Plugins” and Semihosting with Kinetis Design Studio. With using the GNU ARM Embedded (lauchpad) in my Kinetis Design Studio, time for a ‘summary’ post :-).

Proof of Concept: Open Source ARM SWD Debug and General Purpose Board

Posted on by

The Teensy is a great and tiny board (see “USB CDC with the Teensy 3.1 Board“), but it lacks real SWD/JTAG debugging capabilities (see “Hacking the Teensy V3.1 for SWD Debugging“). The Freescale Freedom boards are great, but for many applications too big, and have potentially too many components on it. So what about building a breadboard friendly tiny board which *has* SWD debugging ability *and* can be used to debug another boards?

So here is a working prototype based on the FRDM-K20D50M:

Serial Terminal View in Eclipse Luna

If you have read my article “Serial Terminal View with Eclipse Kepler“, then you are aware that using a Terminal view to a serial connection (COM port) under Eclipse Kepler is pretty much broken. I’m moving some of my projects to the more recent Eclipse Luna release, and the good news is that support is back 🙂

UART with the FRDM-KL02Z Board

Posted on by

In my classes I’m mainly using the Freescale FRDM-KL25Z board, as it provides the best value for the money, and 128 kByte FLASH with 16 kByte of RAM is enough for many smaller projects. I do have as well the FRDM-KL02Z Board (32 KByte FLASH, 4 KByte of RAM) which is an inexpensive board to evaluate the smaller KL02Z microcontroller. Because someone reported a problem not being able to use the UART over OpenSDA/USB-to-CDC bridge, I have created a demo project which communicates with a console on the host.
