Attaching to a Running Target with Segger J-Link, GDB and Eclipse

Posted on by

This happens several times for me: I have a board running for a while (even for days), and then it crashes or is stuck somewhere. Yes, I usually use a watchdog do recover from that situation. But it would be good to know and debug the problem. With CodeWarrior I had the functionality in the debugger to ‘attach’ or ‘connect’ to a running (stuck/crashed) board. However, with Eclipse/Kinetis Design Studio/GDB this is a different debugger, and not possible. At connection time with the debugger the target does a reset, so I don’t know any more where the application crashed. But now I have a solution, at least with the Segger GDB :-).

Sometimes it is all about knowing the simple tricks, even if they might be obvious ;-). In my post “Eclipse Performance Improvement Tip: Close Unused Projects” I explained why it is important to close the ‘not used’ projects in the workspace to improve Eclipse performance:

Code Coverage for Embedded Target with Eclipse, gcc and gcov

Posted on by

The great thing with open source tools like Eclipse and GNU (gcc, gdb) is that there is a wealth of excellent tools: one thing I had in mind to explore for a while is how to generate code coverage of my embedded application. Yes, GNU and Eclipse comes with code profiling and code coverage tools, all for free! The only downside seems to be that these tools seems to be rarely used for embedded targets. Maybe that knowledge is not widely available? So here is my attempt to change this :-).

Or: How cool is it to see in Eclipse how many times a line in my sources has been executed?

Adding Multiple Include Paths to Build Settings in Eclipse

Posted on by

In Eclipse and CDT, I need to tell the compiler where it has to search for the header files. The normal way is to go to the compiler settings (menu Project > Properties > C/C++ Build > Settings) and then add the include paths, one by one, using the ‘+’ icon:

But for many include paths, this is a time-consuming process. But there is another way.
