single step buttons disabled on Eclipse

[nav]

I've setup Eclipse GCC tools for building and debugging as per the nAN-29 app note (and lot of online help) and able to build the code. However, the debugging is working only partially. When the debug is launched, it programs the chip and goes into main and halts. However, the buttons for debugging are disabled (step into, step out, restart, run etc). I can only right click and select "Run to line". What could be wrong?

Are you using Luna ? I know Luna has that problem with the plugins. Kepler works fine.

Hi,

I have same problem. Just stop and restart eclipse and step button will appear again.

Bests regards Jérôme

Hi, I can confirm that I see the same bug in Luna. According to the GNU ARM Eclipse Plug-in page this is a known issue:

"The debugger buttons are disabled If you upgraded to Eclipse Luna 4.4, and you notice that the debugger buttons are not available (in fact the buttons are still there, but are greyed/disabled), you are facing a Luna CDT bug. The workaround is to quit Eclipse and to retry."

You can either follow this workaround, or use Kepler instead as suggested by Dusautois.

I can confirm that this bug is present on both the Windows and Linux builds of Eclipse. Restarting Eclipse will fix the problem until the next time Eclipse is started (at which point you'll need to restart Eclipse again).
