It has been a while since I published my ‘build my own DIY IDE’ (see “DIY Free Toolchain for Kinetis: Part 1 – GNU ARM Build Tools“). I have used that approaches in my classes successfully. Now a new semester is coming up, so time to update the instructions using the latest Eclipse IDE (Mars) and tools (GCC ARM Embedded (launchpad) with GNU ARM Eclipse).

Some might say that Eclipse is too powerful and has too many features. But to me, the many small and somehow hidden gems can make a big difference in my daily life. One of these features is ‘Step Into Selection’ while debugging.
Very often I have a source line with nested function calls like this:

Those who understand binary and those who don’t.”

In “CodeWarrior Flash Programming from a DOS Shell” I showed how to program a device from the DOS shell. Because that example was for ColdFire and CodeWarrior for MCU10.2, here is the same for a Kinetis (FRDM-KL25Z) and CodeWarrior for MCU10.6. In my workspace (c:\tmp\wsp_10.6) I have a project folder (FRDM-KL25Z).
I’m using the ‘Flash Programmer’ to sneak the needed commands:

It was a very warm (32°C) and beautiful summer Sunday. Spent some time at the ‘house lake’. The picture shows a view over Lake Lauerz to my home village on the other side:

Far to the left the Rigi, with the Rossberg in the middle. On the left of the Rossberg is the rock slide area from 1806 (see “Hacking the Heating System for Cooling – Geothermal Drilling with extra Benefits“). On the right the Spiegelberg and then far to the right part of the Mythen.
Happy Laking 🙂
Segger releases often new application and firmware updates. If I install an IDE like the Freescale Kinetis Design Studio, it comes with that firmware version available at that time. How to take advantage of a new Segger release?

I need to program several boards with a firmware: a number too small for serious batch/factory programming, but a number too high doing this with the debugger. I want this:
Need to program a few boards…
I have published a Sneak Preview how GNU gprof profiling looks for an embedded target ARM Cortex-M in an earlier post:
This tutorial explains how to profile an embedded application (no RTOS needed) on ARM Cortex-M devices with GNU gprof. Additionally I explain the inner workings to generate the data necessary for gprof.

So I make a panorama shot to the west to my home village and the Rigi mountain int the background. Rain is coming soon…
