@Vidar Berg, After this example, I encountered several more times when I debug the examples in Eclipse. My 'standard' workaround is, property->c/c++ build->Build variables, then add the PATH (the table is empty when I opened it for the first time).

Thanks for the update. I'll try to look into this to see why the variable is not always being set and update the tutorial when time permits.

Hi Vidar, Before reading your answer, I have made been able to debug. In the GDB client setup, Executable users ${cross_prefix}gdb${cross_suffix}. I changed it to arm-none-eabi-gdb, it also works.

cheers.

Hi,

I haven't figured out why yet, but for some reason the ${cross_prefix} is not always being set to arm-none-eabi (used in the executable field of the GDB Client setup). It's probably related to the project setup. The result is that the debug launcher calls gdb --version while it should call arm-none-eabi-gdb --version.

Fix:

Change ${cross_prefix}gdb${cross_suffix} to arm-none-eabi-gdb

@Uly: Segger GDB server needed for debugging. When you install Segger software pack, GDB will be installed by default.

I just make the debugging on the examples run, without knowing what has happened inbetween, I will update when I figure it out!

Hi Hung, after unchecking "start the Jlink GDB server locally", I still can not debug. The error says

> "Error in final launch sequence Failed

> Failed to execute MI command:

I don't install gdb on my mac, is dgb also necessary expect for the Jlink GDB? Thanks!

Hi Uly,

I would suggest to test first with unchecking the "Start the Jlink GDB server locally ". Then you can try to start the GDB server manually and see if you can start debugging.

If you can, then it must be something wrong with the GDB path configuration in your Eclipse.
