Speeding up the Debug Launch in CodeWarrior

Posted on by

Whenever I do a debug launch in the Eclipse based CodeWarrior, it takes some time until actually I’m ready to step through my code on the target. Yes, a good part of that is by Eclipse. But another part is that Eclipse helps me to do stupid things (which is a good thing). But say if I know what I’m doing, I could remove some of that safety belts and still doing fine. But only if I know what I’m doing.

A good indicator where Eclipse is spending time is to have a look in the Progress View:

It shows an interesting information: ‘Build before Launch’….

Assembly Instruction Stepping

Usually I debug and step on C and C++ level: means I step on C/C++ source lines. But sometimes a finer stepping detail is required. What I need is stepping on assembly level. For first time users of Eclipse, that might not be that obvious, so here is the hint:

In the Debug view toolbar (while debugging), there are the normal stepping commands like ‘step’, ‘step over’ or ‘step out’. All these stepping can be performed on assembly instruction level if I enable the ‘Instruction Stepping Mode’:

Instruction Stepping Mode: Assembly level stepping

Instruction Stepping Mode: Assembly level stepping

Copy my CodeWarrior Project

I have a project working, and then I want to do a copy. Unfortunately, this is not as simple as it should be :-(. In order to copy a project with all the settings, some knowledge about the internals of the project structure is required, which is the topic of this post.

In “Copy my Project” I was using a ColdFire V2 project which is not an easy case, as is using a Target Task to flash the microcontroller. Fortunately, all other targets in CodeWarrior for MCU are *not* using target tasks :-). With little help and preparation, a copy a project is not that difficult to do.  I’m showing how to do this with the FRDM-KL25Z project I have created in this post.

Removal of Processor Expert for a Project

Posted on by

Yes, I’m using Processor Expert *a lot*. But there might be reasons to go without it. Because then I really want to do it the hard-hard-hard core way. Or maybe because I have configured my system, and want to freeze my code. And nothing prevents me to do it ‘my way’.

In any case, it is easy to transform a CodeWarrior Processor Expert project, and then decide to remove that technology from it, and go further with the ‘traditional’ technology.

A Library with ARM gcc and Eclipse

When I create a new bare-board project with the Eclipse based CodeWarrior 10.3 for my FRDM-KL25Z board and GNU gcc, then the ‘Library’ option is grayed out:

Library Option in New Project Wizard

Library Option in New Project Wizard

This does *not* mean that libraries cannot be built :-). In fact it is very easy to do this with the GNU tools and Eclipse, and here is how….

Compiler Defines and Eclipse Editor Highlighting

Posted on by

In this post I have found settings for Eclipse Indexer to show the state if defines correctly. Usually I have something like this in my projects:

debug me

debug me

So I define the macro DEBUG_ME on the compiler command line. And it is cool to see that the Eclipse editor correctly grays out the code which is not enabled. But for this the Eclipse Editor view needs to know about the macro, but how does this work?

White Space or not, that’s the question

There are times when I want to know *exactly* what is inside my source files. In my article on EHEP explains how to get down to the hex bytes of a source file. But in many cases I’m interested to see the non printable/white characters only. Showing white spaces in the sources is easy in Eclipse: I use the ‘Show Whitespace Characters‘ toolbar icon:

CodeWarrior for MCU10.3 beta is now available

Today is the ‘L Day’ for Freescale: After the announcement of the Cortex-M0+ family (Kinetis-L) earlier this year, it has been launched on the Freescale web site. Given the positive echo on my post around the KL25Z Freedom board (which has a Kinetis Cortex-M0+ KL25 on it) and the fact that production board is shipping these days, a lot of engineers were waiting for the CodeWarrior for MCU10.3 as it is in my view the development tool of choice as well for ARM Kinetis-L. And right on time, the MCU10.3 beta is available for download on http://www.freescale.com/cwmcu10. Time to show what I have noticed as new and noteworthy…
