A Conference, Yellow Flowers and Green Bugs …

I’m spending a few days off in the Alps these days, if you are wondering :-). So I share a few wildflower pictures (click to enlarge) from the hiking tours today. Many trails were closed due the security measurements for the Bilderberg summit in the area, so we had to change our plans.  First I thought it was for the G7 summit which is over and was on another alp in Germany. But then I realized that they did that massive thing (military forces, no-fly zone, mobile radar systems, etc) for that Bilderberg conference too. At least it did not impact us much, except using alternative routes, hikes and trails.

One of 80’000: Lightning Struck over Lucerne Area

In Switzerland, Meteo Schweiz normally counts 200’000 to 500’000 lightnings every year. On June 7th 2015, the system counted over 80’000!  In that evening, a heavy thunderstorm moved over most parts of Switzerland. I have not been able to take good pictures myself, but Michael Uebelhart shared that one from the Bürgenstock overlooking the Lucerne area with me:

Eclipse Project ‘Refresh Policy’: Broken Incremental Build with External Make?

Posted on by

So here is a problem I have observed for a while, and several users have reported that to me: the problem is that for some reasons and only for some projects, when I do a ‘build’ in Eclipse CDT, it does a ‘full’ build. It does not only build the changed files, it builds all or many files in the project.

I expect that only the changed files will be rebuild. Instead, it compiles many files it should not compile/build, with the result that a build takes a very long time. That’s clearly wrong, and not what I expect. So what is causing this problem?

Preparing for Austin/TX – with no Rudy’s Sauce

YES! I’m going to attend the Freescale Technology Forum conference (http://www.freescale.com/ftf) in Austin, Texas Jun 22-25 this year. Right on time, as I have run out of Rudy’s BBQ sauce (see “Smoking BBQ Baby Back Ribs – Swiss Style“): I will need to travel light so I have enough space and weight room for bringing back BBQ sauce :-). But ‘no sauce’ does not mean ‘no BBQ‘!!!!

Code Coverage with gcov, launchpad tools and Eclipse Kinetis Design Studio V3.0.0

What makes Eclipse great: using open source tools there are a lot of tools and techniques available which usually are only provided for desktop development.

A while back I described how to do code coverage with Eclipse Kepler and the GNU ARM Embedded (launchpad) tools (see “Code Coverage for Embedded Target with Eclipse, gcc and gcov“). With Kinetis Design Studio out, time to do the same with that Eclipse distribution, especially as Freescale is now using the stock GNU ARM Embedded tools too.

Problem: undefined reference to ‘__end__’ if using Semihosting

In case you are running into the following GNU linker error about a missing __end__:

'Building target: MyProject.elf'
'Invoking: Cross ARM C++ Linker'
...
toolchain/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/lib/armv6-m/rdimon-crt0.o: In function `_start':
(.text+0xdc): undefined reference to `__end__'
collect2.exe: error: ld returned 1 exit status
make: *** [MyProject.elf] Error 1
Failed link because missing __end__

Failed link because missing __end__

The GNU linker complains that rdimon-crt0.o needs the symbol __end__.  This symbol marks the end of the user data/RAM section, and is needed by the rdimon library specs which is used with semihosting.
